Scientific name Two species of planthopper infest rice. The Brown Planthopper (BPH) Nilaparvata lugens (Stål) has become a number one threat to tropical rice production in many parts of Asia in the last three decades (Dale, 1994). The brown planthopper (BPH) is an insect pest of rice in Terai. Brown planthopper (BPH), Nilaparvata lugens (Stål), is one of the most destructive insects that impair rice productivity per year. Because resistance in these lines was conditioned by single major genes, and because phenotyping was a relatively straightforward process, brown planthopper resistance was transferred relatively quickly to cultivars with improved semidwarf plant types and good grain quality. Host-plant resistance is the most desirable and economic strategy in the management of BPH. | Towards understanding of molecular interactions between rice and the brown planthopper. Guttikonda H, Thummala SR, Agarwal S, Mangrauthia SK, Ramanan R, Neelamraju S. Sci Rep. 2020 Mar 17;10(1):4873. doi: 10.1038/s41598-020-60922-6. Number of the larvae bored into the rice stems were counted after 24 h of inoculation, S.K. Interestingly, much if not most of the economic damage done by spittlebugs is due to native spittlebug species colonizing nonnative hosts (e.g., introduced forage grasses, and clovers). We show that the brown planthopper (BPH) has cleverly turned this around by exploiting herbivore-induced plant volatiles (HIPVs) that provide safe havens for its offspring. The insects usually acquire the pathogen by feeding on an infected plant, but some pathogens may be transmitted transovarially from mother to offspring. Recently, the effectiveness of neonicotinoids has diminished due to the emergence of resistant strains including the silverleaf whitefly, Bemisia tabaci; the aphid, M. persicae; the brown planthopper, Nilaparvata lugens, or the Colorado potato beetle, Leptinotarsa decemlineata. Genomic information for BPH is currently unavailable, and, therefore, transcriptome and expression profiling data for this species are … What it does High populations of planthoppers cause leaves to initially turn orange-yellow before becoming brown and drying. Be careful of the outbreak of Brown planthopper (BPH) due to drought. Therefore, breeding hybrid rice resistant to BPH is the most effective and economical strategy to maintain high and stable production. Altered expression of PALs significantly…, Altered expression of PALs significantly impacts BPH resistance. Similarly, grain yield and drought resistance of the upland cultivars can be improved using major QTLs for grain yield under upland drought stress (Bernier et al., 2007) using marker-assisted recurrent selection (MARS). In the present study, … Phenylalanine ammonia-lyase (PAL) is a key enzyme involved in plant defense against pathogens, but the role of PAL in insect resistance is still poorly understood. Repetition of the study with other races or other pure line varieties, or with both. The brown planthopper (BPH) Nilaparvata lugens (Hemiptera: Delphacidae) is one of the most devastating insect pests of rice . Anamorphic Ascomycota also host necrotrophic parasites. Hawksworth (1981a) gives a long list of additional mycoparasites growing on conidial fungi. Split nitrogen into three applications during crop growth to reduce BPH buildup. Further screening efforts identified other rice lines with other genes for resistance to the brown planthopper (Khush, 1989). ), African maize leafhopper (Cicadulina spp. A number of genes have been identified as resistant against different insect-pests but resistance broke down within a short timespan. The amino acid asparagine is a feeding stimulant for the brown planthopper, and levels of sulphur-containing amino acids influence planthopper performance (Horgan, 2009). Briggs and Knowles (1967) mentioned that resistance studies usually require the following: Pure lines of the host to serve as resistant and susceptible parents of crosses, A uniform and ideal environment of the pathogen or insect, such that resistance and susceptibility are clearly differentiated, A suitable method of inoculation or infestation so that the disease or insect has an equal opportunity for development on all materials of the study, A consistent system of classification preferably similar to that used by others conducting similar studies, Provision to grow self progenies of a cross through F3 since F3 families give the best measure of the F2 genotype. In the past, a number of genetic studies on disease- and insect-pest-resistant varieties were conducted. 2013). Oxalic and silicic acids as well as certain flavonoids and plant sterols can act as feeding inhibitors to brown planthoppers, but causal links between the presence of these compounds and resistance have not been firmly established (Bottrell and Schoenly, 2012). Epub 2013 Feb 9. The rice brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae), is one of the most serious pests of rice in Asia. Emphasis should be given to understanding the role of soil microbes and their interaction with rice roots in promoting NUE. Biocontrol of the plant-pathogenic Verticillium dahliae has been attempted repeatedly, as reviewed under “Mycoparasites of Mycelia, Ectomycorrhizae, Sclerotia, and Spores in Soil.” Alternaria brassicae, Pleospora species, and Trichothecium roseum are highly susceptible to hyphal interference by Verticillium luteo-album (Tsuneda et al. This yeast also acts similarly against Rhizopus stolonifer, Botrytis cinerea, and Alternaria alternata on tomatoes and grapes. Knockdown of OsPALs significantly reduces BPH resistance, whereas overexpression of OsPAL8 in a susceptible rice cultivar significantly enhances its BPH resistance. BPH is a small brown insect found mainly on the base of rice plants above the water level. We had found that BPH exhibits a strong preference for rice plants (Oryza sativa) that are already infested by … (2008) showed that over 100 genes were differentially expressed following brown planthopper feeding on varieties possessing or not possessing the Bph-14 and Bph-15 resistance genes. Understanding these mechanisms will lead to a better understanding of life history evolution and the realm of possible phenotypes available. He further investigated the behavior of the borer in a Petri dish containing rice stem pieces with various Si contents, which was prepared by application of silica gel. 2020 Aug 5;10(8):2653-2660. doi: 10.1534/g3.120.401372. Mol Plant. What does BPH stand for? BPH mainly sucks rice phloem sap and transmits plant viruses, i.e., the rice … Twenty-one major genes for BPH resistance have been identified by During the feeding process, BPHs secrete saliva into plant tissues, which plays crucial roles in the plant-insect interactions. Among the most important are the brown planthopper, sugarcane planthopper (Perkinsiella saccharicida), corn planthopper (Peregrinus maidis), meadow spittlebug, beet leafhopper (Neoaliturus tenellus), potato leafhopper, corn leafhopper (Dalbulus spp. Large-scale screening efforts at the International Rice Research Institute (IRRI) employing the ‘seedbox’ method described above identified a number of rice lines with very high levels of resistance to brown planthopper (Khush, 1989; Pathak, 1969). To exploit potential target genes for applications in transgenic rice to control this sap‐sucking insect … The authors declare no competing interest. Common name . Brown planthopper (BPH) Nilaparvata lugens Stål is a serious insect pest of rice in Asian countries. Be careful of the outbreak of Brown planthopper (BPH) due to drought. In Varanasi, India, Colletotrichum dematium is parasitized by Acremonium sordidulum, which smothers the host and reduces its sporulation on the plant (Singh et al. The brown planthopper (BPH), Nilaparvata lugens Stål, is a major rice pest in many parts of Asia. Background: Among various pests, the brown planthopper (BPH) that damages rice is the major destructive pests. Outbreaks of brown planthopper have occurred throughout the history of rice cultivation, but outbreaks became more frequent and more intense after the introduction of improved rice varieties and input-intensive farming practices during the green revolution of the 1960s. Desaturases are essentially required for unsaturated fatty acid (UFA) biosynthesis. Nguyen Cong Thuat, Dias van Thans, 1984. Genome-wide identification of R2R3-MYB family in wheat and functional characteristics of the abiotic stress responsive gene TaMYB344. Raising yield potential: Integrating genomic tools, physiological traits, and diverse germplasm is emphasized for increasing rice productivity. Cartwright and Wiebe (1936) called these genes H1 and H2. However, the molecular mechanisms underlying BPH6 are poorly understood. Large chromosomal segments corresponding to QTLs associated with root length in a population derived from a cross between the deep-rooted upland variety Azucena and the shallow-rooted lowland variety IR64 were introgressed into the IR64 background. Introduction. Contrary to these traits, no well-defined genes/QTLs are available for abiotic stresses, such as drought, salinity, heat, or cold, along with nutrient uptake, grain nutrition, and cooking and eating quality. Human resource development: Since genomics technologies are expanding at a faster rate, regular training of young breeders should be strengthened. A few examples have been cited to illustrate the above mechanism. Adults and young suck the plant sap from leaf sheathes, causing yellowing of lower and then upper leaves. Recently, the BPH-resistance gene, BPH6, was cloned and applied in rice breeding to effectively control BPH. The brown planthopper (BPH), Nilaparvata lugens, is a serious threat to rice production in Vietnam and insecticides are widely used for its control. Equally important is trait development for newly emerging diseases, such as false smut. The neonicotinoid resistance is principally attributable to the enhanced detoxification by cytochrome P450 monooxygenases (Karunker et al., 2009; Puinean et al., 2010). It is a rice-specific herbivore that ingests assimilates from the phloem leading to stunted … Here, we purified and characterized a gustatory receptor (protein) coding gene, NlGr7, from the brown planthopper (BPH) Nilaparvata lugens, which is an important insect pest of rice. Increased potassium reduces planthopper susceptibility as cell walls get thicker because of greater silica uptake. Table 7.62. Genome-wide transcriptome profile of rice hybrids with and without Oryza rufipogon introgression reveals candidate genes for yield. Turhan (1993) found a number of additional, interesting antagonists of Alternaria alternata, particularly Dicyma olivacea, Stachybotrys elegans, a species of Sesquicillium, five species of Myrothecium, and Coniothyrium sporulosum. Neither H1 nor H2 imparts resistance to Hessian fly in the Corn belt and a third gene H3 was identified from the variety W38 which imparts resistance to Corn belt type (Caldwell et al., 1946). In a broader sense, designer rice refers to the directed transfer of desirable alleles at target loci while retaining the key characteristics of recipient lines, which have unique adaptability because of either wider adaptation or region-specific quality traits. Pairs of, Bostanian et al., 1984; Volkmar, 1989; Volkmar and Wetzel, 1992, Culin and Yeargan, 1983; Volkmar and Schützel, 1997; Volkmar and Schier, 2005, Vollrath et al., 1990; Volkmar et al., 1998, 2002, 2004, Mechanisms regulating phenotypic plasticity in wing polyphenic insects, Abigail M. Hayes, ... Laura Corley Lavine, in. Germplasm characterization: With genome sequencing becoming high-throughput and relatively inexpensive, the characterization of modern varieties and megavarieties, landraces, primitive cultivars, and wild species through whole genome sequencing is emphasized for the identification of desirable and rare alleles that have been left out of the main breeding programs. The brown planthopper (BPH) Nilaparvata lugens(Stål) is one of the most serious insect pests of rice in Asia. Keywords: … Taken together, our results demonstrate that the phenylpropanoid pathway plays an important role in BPH resistance response, and provide valuable targets for genetic improvement of BPH resistance in rice. imidacloprid) is the chief way to control BPH… In addition, nAChR mutation may partly be associated with reduced IMI mortality and receptor sensitivity, involving Tyr to Ser (adjacent to loop B Trp) of α subunit in Nilaparvata or Arg to Thr (neighbouring loop D Trp) of β subunit in Myzus (Bass et al., 2011; Liu et al., 2005). ), green rice leafhopper (Nephotettix spp. bph の定義が複数ある場合がありますので、bph のすべての意味については辞書で 1 つずつチェックしてください。 英語で定義:Brown Planthopper BPHの他の意味 See this image and copyright information in PMC. BPH can also transmit Rice Ragged … Wei Q, Chen R, Wei X, Liu Y, Zhao S, Yin X, Xie T. BMC Genomics. Till to date, 38 BPH resistance loci have been mapped from cultivated and wild species of rice. This study investigates the proteomics of BPH interactions with three rice cultivars: the first resistant (PR) to BPH… COVID-19 is an emerging, rapidly evolving situation. It uses its stylet to penetrate rice phloem, feeding on rice sap and causing direct damage to rice or even plant death. The brown planthopper (BPH) Nilaparvata lugens (Stal) is a serious pest of rice in Asia. The newly developed cultivars having the Sub1 QTL have more than 97% of the genome from the recurrent varieties (Swarna, Sambha Mahsuri, BR11), except for the Sub1 region on chromosome 9, and provide enhanced submergence tolerance for up to 14 days to these varieties (Septiningsih et al., 2009). Then the dominant genes controlling resistance were also found. is a pest of rice in Asia; damage is caused by direct feeding and by the transmission of rice ragged stunt and rice grassy stunt diseases. Hansfordia (Dicyma) pulvinata is a destructive parasite on many dematiaceous conidial fungi (Hepperly 1986), particularly Cercospora (Hawksworth 1981b), but also Passalora (Mycovellosiella, Cladosporium, Fulvia) fulva on tomato (Peresse and Le Picard 1980; Le Picard and Trique 1987), and P. (Cercosporidium, Phaeoisariopsis) personata on peanut leaves (Mitchell et al. Revealing different systems responses to brown planthopper infestation for pest susceptible and resistant rice plants with the combined metabonomic and gene-expression analysis. The use of Auchenorrhyncha in biocontrol of weeds has also begun to be explored. To date, over 20 Bph resistance genes have been identified from cultivated and wild Oryza species, although not all have been incorporated into resistant varieties (Bottrell and Schoenly, 2012). Heavy infestation by BPH … Jian Feng Ma, Eiichi Takahashi, in Soil, Fertilizer, and Plant Silicon Research in Japan, 2002. Pandey, in Integrated Pest Management, 2014. 1986, 1987). There are adults with either long or short wings (see below, left). To date, 29 major BPH resistance genes have been identified from indica cultivars and wild rice species, and more than ten genes have been fine mapped to chromosome regions of less than 200 kb. Phloem-limited viral and mycoplasmalike pathogens typically multiply within the vector and enter the plant when the insect injects saliva during feeding. Cicadas are used as food by several human cultures. Outbreak frequency of Nilaparvata lugens (brown planthopper; BPH) has been increasing in Asian rice growing countries in recent years (2005–2012) .These trends are widely linked to adverse effects on BPH … Brown planthopper (BPH) causes the most serious damage of the rice crop globally among all rice pests. HHS Genome-Wide Characterization and Comparative Analysis of MYB Transcription Factors in. brown planthopper; lignin; phenylalanine ammonia-lyase; rice; salicylic acid. It … The stem supplied heavily with N contained some compounds that were extractable with alcohol or ether and attracted the borer, and the biosynthesis of such compounds seems to be suppressed by Si application. Few studies actually investigate the effects of insecticides other than their direct toxicity (usually LD50) on non-target animals. Du B, Zhang W, Liu B, Hu J, Wei Z, Shi Z, He R, Zhu L, Chen R, Han B, He G. Proc Natl Acad Sci U S A. insects, the brown planthopper (BPH) (Nilaparvata lugens Stål) is the most destructive pest to rice production. The brown planthopper (BPH), Nilaparvata lugens Stål, is one of the major pests of rice. Silicon suppresses insect pests such as the stem borer, brown planthopper, rice green leafhopper, and whitebacked planthopper, and non-insect pests such as leaf spider and mites. 3. Efforts should be made to identify diverse genes/QTLs with different mechanisms for all these traits. Background The brown planthopper (BPH) Nilaparvata lugens (Stål) is one of the most serious insect pests of rice in Asia. The variety ‘Mudgo’, for example, showed near-complete immunity to the brown planthopper, with 100% nymphal mortality after 10 days (Pathak, 1969). Nutrient-use efficiency: Molecular approaches should be used as a priority for the identification of genes for efficient nutrient uptake and transport. Biffen (1905) demonstrated that the resistance gene for stripe rust in wheat was controlled by a single recessive gene. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error, Lignin accumulation is associated with BPH resistance in rice. Biological nitrogen fixation: Breeders should explore the possibilities of enhancing BNF through endophytes. Introduction. He found that the stems attacked by the stem borer contained less Si. 1991). Host-plant resistance is an important strategy to reduce the damage caused by BPH and increase rice productivity. Noble and Suneson (1943) reported from the crosses of resistant variety Dawson and two susceptible varieties Poso and Bigclub, that Dawson had the dominant duplicate gene for resistance. The brown planthopper (Nilaparvata lugens Stål; BPH) has become a severe constraint on rice production. There are dark and light types regarding body color. What is the abbreviation for Brown Planthopper? Brown planthopper (BPH) Nilaparvata lugens Stål is a serious insect pest of rice in Asian countries. These protective functions of Si may be attributed to Si deposited on the tissue surface. In rice, progress has been made with the introgression of major genes for improving tolerance of bacterial leaf blight, brown spot, brown planthopper, and for several other traits. These include eight First Desaturase family genes, one cytochrome b5 fused desaturase gene (Nlug-Cytb5r) and one Sphingolipid Desaturase gene (Nlug-ifc). It is alarming that a sharp increase in the … What does BPH stand for? So far, emphasis has been primarily on varietal development with limited emphasis on prebreeding and trait development. Integrated Pest Management (IPM) aims to avoid harming natural crop spiders. Brown planthopper (BPH) is one of the most destructive insects affecting rice (Oryza sativa L.) production.Phenylalanine ammonia-lyase (PAL) is a key enzyme involved in plant defense against … The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is a planthopper species that feeds on rice plants (Oryza sativa L.). While studying the inheritance in aphid tolerant cultivars, non-waxy mutant RC 1425 and susceptible Prakash cultivars of B. juncea, Yadav et al. Kumar et al. | In rice, progress has been made with the introgression of major genes for improving tolerance of bacterial leaf blight, brown spot, Although the vast majority of species of Auchenorrhyncha are benign, the group contains some of the most destructive pests of agriculture. Please enable it to take advantage of the complete set of features! Gallun and Khush (1980) reported the effectiveness of a major gene for resistance to jassids in cotton. NIH A considerable effort has been devoted to the mapping of root-related QTLs in rice. ), and various grape leafhoppers (Arboridia and Erythroneura spp.). Growing resistant varieties is the most effective and environment-friendly strategy for protecting the crop from BPH. JA and SA mediated signaling pathways have been extensively identified in plant stress response against pathogen and insect (Berens et al. Migration of the BPH have one of its roots in tropical Vietnam in the Mekong River Delta and the insecticide resistance status of BPH … Knott (1964) and Knott and Green (1965) identified 11 genes for resistance which were transferred to variety Marquis by backcrossing. High population of planthoppers cause leaves to initially turn orange-yellow before becoming brown and dry and this is a condition called hopperburn that kills the plant. Introduction. The Department of Agricultural Extension revealed that during this hot and dry season Rice growers in the central and northern regions observed the period of BPH (Brown planthopper) pest attack on their field. Understanding of the mechanisms of brown planthopper resistance has somewhat lagged behind the development of resistant varieties (Bottrell and Schoenly, 2012), such that there is still ‘no clear mechanistic link’ between resistance genes and effects on brown planthopper fitness (Horgan, 2009). Development of novel control strategies can be facilitated by comparison of BPH feeding behaviour on varieties … The discomycete Bisporella pallescens (synonym Calycella monilifera) fruits densely on the conspicuous black conidial patches of Bispora antennata on tree stumps (Jahn 1968). Breeders in collaboration with biotechnologists should seek to develop various specialized populations, such as RILs, nested association mapping (NAM), multiparent advanced generation intercross (MAGIC), and CSSLs for the mapping of QTLs. Although rice varieties containing major genes for resistance to the brown planthopper exhibit high levels of planthopper resistance, other management practices may nonetheless be critical for the sustainable use of these varieties. This is consistent with what is known about major gene resistance in plant–pathogen interactions, in which resistance genes function in the recognition of pathogen attack and activation of resistance-related gene expression. Epub 2010 Nov 1. pests, the brown planthopper (BPH) has been regarded as one of the main rice production constraints in Asia [3–6]. Brown planthopper (BPH) is the most devastating pest of rice. Identification and characterization of Bph14, a gene conferring resistance to brown planthopper in rice. Azucena root-related QTLs have also been introduced into the indica variety Kalinga III, but only one of the five target QTLs had an effect on root length and none had a consistent effect on grain yield under water-limited conditions (Steele et al., 2006). The development and cultivation of BPH-resistant varieties is the most economical and efficient strategy to overcome the destruction caused by BPH. BPH abbreviation stands for Brown Planthopper. Such studies are not often done, presumably because of their costs and methodological difficulties (Vollrath et al., 1990; Volkmar et al., 1998, 2002, 2004). Ultimately this data will help explain how the diverse and successful adaptations and life histories that have evolved and continue to evolve. Brown planthopper (BPH; Nilaparvata lugens Stål) is one of the most destructive insect pests of rice in Asia-Pacific region, often causing hopper burn and severe yield loss due to its monophagy and migration ability (Normile 2008).Presently, spraying insecticides (e.g. The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is a planthopper species that feeds on rice plants (Oryza sativa L.). The first brown planthopper-resistant rice variety, ‘IR26’, which contained the resistance gene bph-1, was released by the IRRI in 1973 and was widely adopted by growers throughout Asia. Auchenorrhyncha injure plants directly through feeding or oviposition or, more often, indirectly through the transmission of plant pathogens. Annual losses to maize, rice, and sugarcane attributed to pathogens spread by leafhoppers and planthoppers are estimated in the hundreds of millions of dollars. As an example, designer basmati rice can be produced by introgressing (through MAS) genes/QTLs for disease (BB and blast) resistance, insect (BPH) resistance, high grain number, sturdy stem, etc., along with retaining genes for its key basmati characteristics, such as aroma, grain length, grain elongation after cooking, alkali spreading value, amylose content, photoperiod sensitivity, etc. In this study, HPLC, MS/MS, and … The lack of repeatability of QTL effects across different populations (QTL × genetic background interaction) and across environments (QTL × environment interaction) are two factors that limit the use of QTLs for MAS by plant breeders (Bernier et al., 2008; Courtois et al., 2003; Lafitte et al., 2004; Price et al., 2002; Serraj et al., 2005). Planthoppers are highly destructive pests in crop production worldwide. Abstract Among the planthoppers of rice, the brown planthopper (BPH) is a major threat to rice production and causes significant yield loss annually. Penicillium funiculosum can smother various fungi in culture and thus prevent pineapple fruit diseases (Lim and Rohrbach 1980). He found that most larvae moved to the stem with low Si content. Brown planthop-per is a rice-specific herbivore and sucks the phloem sap of rice plants … Introduction. The increased importance of the brown planthopper as a pest prompted efforts to identify sources of planthopper resistance. Copyright © 2020 Elsevier B.V. or its licensors or contributors. In rice, a single gene, Bph-1, conferred resistance to brown planthopper in a variety IR 26 but this broke down within 2 years. The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae), is a serious pest of rice in China that causes severe damage to rice directly by feeding and indirectly by acting as a vector for rice viruses (Liao et al. However, little is known about the mechanisms responsible for the development, wing dimorphism and sex difference in this species. Although the insect is endemic in the tropics where 2016 Jan;84:32-39. doi: 10.1016/j.jinsphys.2015.12.001. Milling is affected by several factors, of which chalkiness is important, resulting in heavy grain breakage and poor grain quality. Abigail M. Hayes, ... Laura Corley Lavine, in Advances in Insect Physiology, 2019. The large jaws of the stem borer gnawing rice with a high Si content would wear out more easily than that gnawing rice with a low Si content. Here, an integrated miRNA and mRNA expression profiling analysis was performed on … 1981), which produces a diffusible toxin and induces vesicular deformations in its host. Since several genes/QTLs have been cloned for yield component traits, priority should be given to the pyramiding of yield component QTLs for enhancing yield potential in inbreds, as well as in hybrids. A number of condial Ascomycota are hosts to biotrophic parasites. Grow only two rice crops per year and use early-maturing varieties to reduce their continuous breeding. Furthermore, we show that expression of OsPAL6 and OsPAL8 in response to BPH attack is directly up-regulated by OsMYB30, an R2R3 MYB transcription factor. Emphasis should be given to the pyramiding of genes/QTLs with different mechanisms for resistance to/tolerance of biotic and abiotic stresses. Leafhoppers and planthoppers are among the most significant groups of vectors of plant pathogens, transmitting viruses, bacteria, and mycoplasmalike organisms. On one hand, OsSLR1 … All the BPH-resistance genes identified to date have been from indica rice or wild species. ScienceDirect ® is a registered trademark of Elsevier B.V.

Although the vast majority of species of Auchenorrhyncha are benign, the group contains some of the most destructive pests of agriculture. The QTL regions were very long and the desirable genes may have been lost due to recombination during backcrossing. Constitutive and inducible volatile compounds, including terpenes such as linalool, may be involved in host-plant finding by planthoppers (Xin et al., 2012). Sasamoto (1958, 1960, 1961) investigated the relationship between Si content of rice and behavior of stem borer (Chillo suppressalis Walker). Such resistant biotypes apparently developed as quickly as they did because of the high level of resistance present in ‘IR26’ and because of the simple genetic basis of the resistance.
