Five signals were detected in genomic regions near known candidate genes. The study revealed that the cultivar Kuthiru ranked first based on the cumulative performance index calculated on the basis of thirteen characters including six growth characters and seven yield characters. Key findings: Promising accessions for breeding flood tolerant varieties were identified from the evaluation of two thousand and two accessions of O. glaberrima for tolerance of the three most important flood types affecting rice production in Asia and Africa: flooding at germination (AG), submergence at seedling stages and stagnant flooding. Thus, it is necessary to optimize the tiller number to achieve the maximum yield in rice. All content in this area was uploaded by Mohanan K.V. Transplanted crops generally produce more tillers than direct seeded crops, and dry season crops often produce more tillers than wet season crops. Results showed that proline concentration increased in all the cultivars studied in relation to increase in salt stress and it was progressive along with increase in stress. Amino acid transporters (AATs) play indispensable roles in nutrient allocation during plant development. It is a natural system utilizing indigenous knowledge and local resources. 1.1 Rice Crop Tillers & Panicle This research would focus on phenotyping of rice crops. Genetic Basis of Tiller Dynamics of Rice Revealed by Genome-Wide Association Studies, Heterosis analysis for yield in hybrids involving new plant type and indica lines of rice (Oryza saiva L.), Relative Contribution of Rice Tillers of Different Status Towards Yield. However, comprehensive analyses of the genetic basis of tiller number, considering the development stage, tiller type, and related traits, are lacking. Clear difference in grain yield was observed in the six clusters. Fourthly, compared to LYP9, YLY1 had more productive tillers, compared to LYP9, which results in more effective panicles number per hill (Table 6, Fig. Rainfed Aus rice is a popular conventional rice cultivation technique that through appropriate variety selection can accelerate the benefits of the farmer. A line x tester analysis was carried out in rice with nine new plant type lines and four testers to measure the expression and magnitude of heterosis in single plant yield and nine other yield attributing characters. Plants under drought condition survive by doing a balancing act between maintenance of turgor and reduction of water loss. Selection and further improvement programmes using these cultivars will give rise to promising rice varieties suited for the needs of this special rice ecosystem. Google Scholar, Hao SR, Guo XP, Zhang ZY (2010) Compensation effects of water stress and rewatering on the structure of rice canopy. treatment, number of effective tillers was less than total tiller per hill. Drought limits the agriculture production by preventing the plants from expressing their full genetic potential. Trans Chin Soc Agric Mach 50(01):263–274+284, Xu DH (2016) The present situation and sustainable development of rice in Heilongjiang province. The difference in effective tillers/hill is due to the genetic makeup of the rice varieties. The continual emergence of new tillers takes place from the main stem and these generate their own roots to grow independently, hence ensuring the survival of the gramineous plants u… The two key part of a rice crop that is useful to this research are its tiller and panicle shown in Fig. With respect to the interaction effect of seed rate and row spacing, significant effects were observed on total tillers/m, effective tillers/m, thousand seeds weight and straw yields. secondary and tertiary tillers which come forth at different stages of growth. The maximum number of tillers usually occurred at the late tillering or jointing stage (approximately 40 DAT). Drought is the most devasting abiotic stress that curtails the crop productivity of rice in rainfed areas and most recalcitrant to breeders' effort. Proline is an amino acid which increases in plants under abiotic stress. Universal Journal of Agricultural Research. found that nitrogen fertilizer application increased the number of rice tillers, but not every tiller contributed equally to the overall yield. Rice Panicles The number of tillers per plant will vary according to nutrient status, variety and planting rate (higher seeding rates normally give fewer tillers). Furthermore, the model was validated using independent japonica rice collections, implying that the lead SNPs included in the linear regression model were generally applicable to tiller number prediction. Crops treated without N fertilizer + Azolla 100 kg ha-1 were unable to produce high number of total and effective tillers (Fig. The total land area under cultivation in Chhattisgarh is 5.64 million hectares, out of which rice occupies about 3.85 million hectare. At 150–180 days, at least 50% of the shoots die and a stable population is established. The tillering capacity of rice plants varies with variety, plant spacing, fertility, weed competition and damage from pests. Abstract. Hayayuki . In all the cultivars the total polyamine content got increased starting from the 10mM NaCl treatment itself. https://doi.org/10.1007/s40003-020-00485-0, DOI: https://doi.org/10.1007/s40003-020-00485-0, Over 10 million scientific documents at your fingertips, Not logged in The plants were subjected to different levels of salt stress ranging from 0 to 200 mM of NaCl and the concentration of proline in the leaf samples was inspected. In this study, we sequence 219 Korean rice accessions and construct a high-quality single nucleotide polymorphism (SNP) dataset. The rice japonica variety Nipponbare and the indica variety 93-11, the genomic DNA sequences of which are known, were used to analyze the response of the panicles exserted from the caulis and from various effective tillers at four stages of panicle development to neck blast. (2019) 129 sativa check. For each rice pest, farmers have their own economic injury levels. After maximum tillering has occurred, no more effective tillers are produced. Multiple linear regression models of lead SNPs showed coefficients of determination (R²) of 0.49, 0.22, and 0.41 for the tiller number at the maximum tillering stage, productive tiller number, and productive tiller ratio, respectively. This tall variety gets three feet and is known for its wonderful flavor. Amino acid transporters (AATs) play indispensable roles in nutrient allocation during plant development. Trans Chin Soc Agric Mach 50(11):285–292, Pang GB, Xu ZH, Yang SH et al (2017) Influence factors analysis of rice leaf water use efficiency under controlled irrigation. In rice, miR156 could repress OsSPL14 functions by cleaves its mRNA, and miR156-OE plants resulted in rapid tiller initiation . OsMADS57 expression was significantly reduced in osa-miR444a-overexpressing rice, which showed fewer tillers than did WT . All weed control treatments recorded significantly more number of effective tillers as compared with unweeded control. Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle Tillers are segmented, each segment possessing its own two-part leaf. cultivars of North Kerala under salinity stress has been analysed presently and the results show that the total polyamine content in all the cultivars got increased in relation to the increase in the salt concentration applied. Method to increase effective tillers in Paddy by SherGill Markhai - Duration: 5:38. Rice germinates as a single culmed seedling, but soon after the seedling stage it produces primary, secondary and tertiary tillers which come forth at different stages of growth. the production of high effective tiller number could increase the yield of rice for farmers who apply very little or no inputs at all in their rice production. Maintaining crop yields under adverse environmental stresses is a major challenge facing modern agriculture where polyamines play an important role. Tiller Angle Control 1 (TAC1) is a key regulator responsible for the different tiller angles between japonica and indica rice. © 2008-2020 ResearchGate GmbH. The effective rice LAI has been shown to change among regions by as much as 6 to 10, and the related parameters, such as the extinction coefficient and intercepted photosynthetically active radia- ... groups, N improves the rice population productivity mainly by increasing tillers number. Branching comprises a protective mechanism for higher plants, by assisting with reducing the impacts of injury, and facilitating adaptation to the environment (Horvath et al. All the rice plants were grown in a greenhouse, with 10 h light and 14 h dark, or in the field under natural conditions in summer, Shanghai, China. Access scientific knowledge from anywhere. Increasing the genetic yield potential of rice: prospects and approaches. 4. By a genome-wide association study (GWAS), we detected 20 significant association signals for all traits. - 22.214.171.124. 2: Effective and non-effective tillers of boro rice at harvest affected by variety (S x − = 03916 and 0.0365) Am-Euras. Each tiller will bear a rice panicle, and you can get up to 100 grains of rice per panicle. The hulls fill out well and are easy to harvest. The lowest number of effective tillers/hill (5.95) was recorded in Raniselute. It is said that a tiller of rice plant is a Drought acts a serious limiting factor in agriculture scenario by preventing a crop from reaching the genetically determined theoretical maximum yield. However, the availability of asparagine generated from AS1 reactions is apparently less effective for the outgrowth of tillers. Meri kheti Mera Kisan 29,932 views. Our results improve our understanding of tillering in rice plants and provide a basis for breeding high-yield rice varieties with the optimum the tiller number. Our results improve our understanding of tillering in rice plants and provide a basis for breeding high-yield rice varieties with the optimum tiller number. The drip irrigation treatment had more effective tillers, more roots in topsoil, higher WUE, and greater economic benefit in rice (He, Ma, Yang, Chen, & Jia, 2013), but less yield compare with conventional flooding irrigation. From the main stem, another stem would develop. In order to study the effects of shallow wet–dry irrigation at tillering stage on effective tiller numbers, photosynthetic activity, yield and water use efficiency (WUE) of rice in black soil region, a pot experiment was conducted at Qingan National Irrigation Test Station of Heilongjiang Province from May to September in 2019. The plants were treated with gradually increasing concentrations of NaCl varying from 0-200 mM starting from the 45th day of growth onwards mimicking the gradually increasing salt content of the salinity prone rice farms of the study area and the quantity of total phenolics was investigated in each case. Differences in grain yield and yield components The aim was to see the effects of the weed control treatments on crop growth and yield in boro rice. In order to evaluate the potential mechanism of cultivar differences in rice drought tolerance and to link those traits to yield regulation mechanism, the current investigation was carried out with rice germplasm growing in different water regimes. In this communi-cation, the effect of 1-naphthaleneacetic acid (NAA) on the growth, yield attributes and yield is elaborated. Trans Chin Soc Agric Mach 41(3):52–55+61, Hao SR, Guo XP, Wang WJ et al (2010) After effects of water stress on corn growth atdifferent stages. One accession (TOS 6454) was selected for submergence while four O. glaberrima accessions (IG 48, GERVEX 2674, TOG 7148 and IG 133) were selected for stagnant flooding. Rice is the world's leading food crop, cultivated over an area of about 145 million hectares. Five signals were detected in genomic regions near known candidate genes. Chronological of tillers and their Difference in Grain Yield and Quality among Tillers in Rice Genotypes Differing in Tillering Capacity 137 the mutant reached the highest panicle weight increase rate at 10 and 15 days after flowering, respectively. Based on preliminary screening; 43, 20, and 42 accessions were selected for tolerance to AG, submergence and stagnant flooding respectively. In this study, we demonstrated that inhibiting expression of the rice amino acid transporter OsAAP3 increased grain yield due to a formation of larger numbers of tillers as a … Among the cultivars studied, Kuthiru showed the highest quantity of phenolic compounds and Orkazhama showed the highest percentage of increase of phenolics over the control plants in relation to increase in salt stress. Thus, it is necessary to optimize the tiller number to achieve the maximum yield in rice. Furthermore, tiller number decreased when OsSPL14 mutated at the OsmiR156-targeted site . This concept is recent and it displaces the early concept of high tillering rice varieties. Rice can be grown in different environmental conditions, but wetland cultivation is the most widely used method for rice production. Abstract. Article The proximity to sea and subsequent periodic sea inundation ensure the uniqueness of this system. The yield (Y) and WUE in T1 treatment were higher than that of the other treatments, significantly (P < 0.05). B. Phosphorus. • Therefore, regulation of tiller dynamics is important for crop management; too few tillers limit grain yield and too many tillers result high tiller abortion, poor grain filling and reduction of … Grain yield is a complex character and its expression under specific environment depends on one or more of yield components. The population productivity increased at optimum planting densities. 1. The tillers having filled grains were recorded as effective tillers and the tillers … Rice is the most important food grain crop with regard to human nutrition and caloric intake. ... Foliar application of fertilizers is yet another means to increase the fertiliser use efficiency in rice crop. 2: Effective and non-effective tillers of boro rice at harvest affected by variety (S x − = 03916 and 0.0365) Am-Euras. One in every three people depends on rice for more than half of their daily food (Sureka et al., 2016), Chronological of tillers and their orientation and performance in some salinity tolerant rice cultivars and varieties. IV). It takes 115 days to mature from transplanting. Therefore, it is imperative to develop an efficient and effective in-field technology to quickly detect productive tiller numbers. 1 Tiller of a rice crop  156 K. P. Constantino et al. The rice japonica variety Nipponbare and the indica variety 93-11, the genomic DNA sequences of which are known, were used to analyze the response of the panicles exserted from the caulis and from various effective tillers at four stages of panicle development to neck blast. Subscription will auto renew annually. (2008) and Chowdhury et al. Rice is a semi aquatic monocot, grown in a wide range of ecological conditions. All rights reserved. Tillers in rice crops appear as soon the rice crop is self-supporting (Maclean, Hardy, & Hettel, 2013). However kaippad farms are decreasing in area and the traditional salt tolerant rice cultivars cultivated in the area are also slowly receding from the scene owing to low productivity. Effective tiller was a bit higher in cluster II but panicle length was almost similar across the clusters. Conclusions: We revealed the genetic basis of tiller number in rice plants during growth by a GWAS and formulated a prediction model by linear regression. Rice tillers. The effective panicle number per plant, grain number per panicle, and grain weight per panicle determine the grain yield of a rice plant ( Xing and Zhang, 2010 ). Los Banos (Philippines). J Hohai Univ (Nat Sci) 34(4):397–400, CAS Vol. and loss of productivity. FLOODING. Salt stress tolerant cultivars can be further screened for the production of higher quantity of phenolics in response to salt stress with an objective of improving the antioxidant production potential of such cultivars. Total number of tillers showed significant positive effect on number of productive tillers (0.925) but showed negative effect on panicle length (0.36), hundred grain weight (0.37), biomass (0.04), zinc content in brown Agric Water Manag 206:67–77, Wang JL, Yu GR, Fang QX et al (2008) Responses of water use efficiency of nine plant species to light and CO2 and it’s modeling. Results: We sequenced 219 Korean rice accessions and constructed a high-quality single nucleotide polymorphism (SNP) dataset. In most higher plants, shoot branches develop from axillary buds in the axils of leaves. They are involved in vegetative propagation and, in some cases, also seed production. Agric Res (2020). The plant can perennate through ratoon production. Upland rice cultivars suffer from intermittent moisture stress during critical growth stages especially during germination, tillering, panicle initiation and grain filling period leading to yield loss to a considerable extent. Agricultural Research After panicle initiation, tillers may continue to emerge from preexisting tillers, filling out the space among plants. The difference in effective tillers/hill is due to the genetic makeup of the rice varieties. by changing the practices used to manage rice plants, the soil they grow in, and the water they receive through irrigation, so that the plants can become more productive For rice plants to be more productive, they need to have: • More tillers per plant, • More fertile tillers (panicles) which form from the tillers … Most of the candidate genes were involved in the phase transition from vegetative to reproductive growth. Leaf count indicates a plant’s age and as it grows, its leaves will develop and grow in size . Salinity stress affects the metabolism of plants leading to severe crop damage. Variation in Senescence Pattern of Different Classes of Rice Tillers and Its Effect on Panicle Biomass Growth and Grain Yield 1048 . Most of the candidate genes were involved in the phase transition from vegetative to reproductive growth.

Better crop growth in these treatments might be attributed to more availability of nutrients, water, light and space to crop as a result of effective weed control. Identification of suitable genotypes and their improvement can be used as a potential method to evolve salinity resistant rice genotypesfor different geographical zones. A mutation in the 3ʹ‐splicing site of its fourth intron decreases the level of tac1 , resulting in the compact plant architecture of japonica (Yu et al ., 2007 ). Kaippad is such an indigenous rice-fish farming system of coastal North Kerala in India. Only for earhead bug, do they apply pesticide immediately even if only one bug is seen. The first tiller usually emerges when the seedling has five leaves. The Pn, gs, Tr and Ci in T1 and T2 treatments reached the normal level after re-watering at heading and milk-ripening stages. Flooding is an important abiotic stress affecting rice production in rainfed lowlands of Asia and Africa. Stem rot incidence and severity increase as stand densities are increased; thus, avoid rice stands that are too dense. A high yield- ing semi dwarf rice plant produces a large number of tillers, one in each successive leaf axil at different time intervals; the initiation and development of the tillers are staggered and temporally spaced, but maturation is syn- chronous. Table 3. Tiller outgrowth analysis. WANG Feng, et al. The effective tillers produced by BRRI dhan 29 were 6.94 and 6.45% higher than Aloron and Hira-2. This property was shown by all the cultivars irrespective of the fact whether they evolved in a saline habitat or a non-saline habitat. ... effective tillers per plant in BRRI dhan-29 increased due … Rice is consumed by half of the world’s population. A portion of the late tillers will generally die due to competition effects. Given that the rice yield of a particular plant is ultimately the summed grain weight of all of the grains from all of the tillers of that plant, we expanded our phenotypic analysis to encompass the grain number per tiller.
