New plant type of rice for increasing the yield potential of rice. The two key part of a rice crop that is useful to this research are its tiller and panicle (shown in Fig. Rice is actually the edible fruit, called as a grain or caryopsis. 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 aim was to see the effects of the weed control treatments on crop growth and yield in boro rice. Chronological of tillers and their The total polyamine content in some native rice, Salinity is a major yield reducing factor in coastal as well as arid irrigated rice production systems. WANG Feng, et al. However, proline accumulation was higher in the cultivars collected from the saline tract when compared to the cultivars collected from the non-saline tract. At 150–180 days, at least 50% of the shoots die and a stable population is established. A portion of the late tillers will generally die due to competition effects. The total land area under cultivation in Chhattisgarh is 5.64 million hectares, out of which rice occupies about 3.85 million hectare. Tillers from the rice plant emerge in a specific chronological sequence and it mainly depends on its duration and morphology. 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. 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. Roots are few, thin and elongated. All content in this area was uploaded by Mohanan K.V. https://doi.org/10.1007/s40003-020-00485-0. Four-week-old rice seedlings were used for analysis; plants were peeled carefully to expose the young tiller buds in the basal region where tillers begin to develop. In particular, HD1 was simultaneously associated with the productive tiller ratio and heading date, indicating that the photoperiodic heading gene directly controls the productive tiller ratio. It is said that a tiller of rice plant is a Tillering potential of rice, an important aspect in rice cultivation, is genetically controlled. 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. Grain yield showed the average reduction by 34.19% being highest in genotype Luchai (50.91%) and lowest in Urai buta(8.59%). Among the cultivars studied, Orthadian showed the lowest amount of total polyamine content and Kuthiru showed the lowest percentage of increase in relation to increase in salinity. Vol. RESEARCH ARTICLE Agbeleye et al. (2008) and Chowdhury et al. To further understand how phenotyping works, specifically of a rice crop's height and tiller count, its biology needs to be discussed. Performance evaluation of five popular rice cultivars was attempted based on performance index and cumulative performance index to find out the most promising among the traditional varieties. This property was shown by all the cultivars irrespective of the fact whether they evolved in a saline habitat or a non-saline habitat. North Rice 44(05):66–71. Rice is the most widely consumed staple food for more than half the world's human population. Effective tiller: The results showed that the main effect of heat FLOODING. In rice, miR156 could repress OsSPL14 functions by cleaves its mRNA, and miR156-OE plants resulted in rapid tiller initiation . While, panicle length and number of grains per panicle were higher under PTR. B. Phosphorus. 5:38.

Trans Chin Soc Agric Eng 32(24):114–123, Wei YX, Zhang ZX, Zhao YS (2010) Study on theory and technology of soil and water conservation in sloping farmland. In all the cultivars the total polyamine content got increased starting from the 10mM NaCl treatment itself. The highest total polyamine content was noted in the cultivar Orkazhama followed by Kuttusan and Kuthiru which were collected from a traditional saline rice tract of North Kerala. In respect of production, India ranks second with 95.68 million tonnes of paddy (Anonymous 2006). We revealed the genetic basis of the tiller number in rice plants during growth, By GWASs, and formulated a prediction model by linear regression. Typically, late emerging tillers do not contribute significantly to the grain yield of rice (Wang et al.2007); however, theoretically, they possess the potential for high productivity, due to the totipotency of rice coleoptile tissue (Oinam and Kothari 1995). Some cultivars produce ratoon crop for several years. We inspected the immediate accumulation of proline in salinity induced stress in seven native rice (Oryza sativa L.) cultivars. tillers (0.29), number of productive tillers (0.36) and cooked rice iron (0.22). The number of tillers, effective tillers, lesion height and disease reduction were measured 45 days after inoculation in 1997 and 1998. They are involved in vegetative propagation and, in some cases, also seed production. The highest percentage of increase in total polyamines was noted in the cultivar Kunhutty followed by Kuttusan and Veliyan.Kunhutty and Veliyan are cultivars collected from a non saline rice tract. Google Scholar, Wang CY, Wang BL, Zhang WX et al (2008) Effect of drought period on yield and yield components of rice. Drought is the most devasting abiotic stress that curtails the crop productivity of rice in rainfed areas and most recalcitrant to breeders' effort. In particular, HD1 was simultaneously associated with the productive tiller ratio and heading date, indicating that the photoperiodic heading gene directly controls the productive tiller ratio. Most of the candidate genes were involved in the phase transition from vegetative to reproductive growth. 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. 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. Salt induced abiotic stress is an acute problem, interrupting the metabolic processes of plants, resulting in reduced growth and productivity. The cultivars collected from both the saline and non-saline rice tracts showed gradual increase in the accumulation of total phenolics in response to increase in salt stress. 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. They are involved in vegetative propagation and, in some cases, also seed production. After maximum tillering has occurred, no more effective tillers are produced. Tiller outgrowth analysis. Tillers are segmented, each segment possessing its own two-part leaf. The tillers having filled grains were recorded as effective tillers and the tillers … ... effective tillers per plant in BRRI dhan-29 increased due … Maximum tiller population is reached between 90 and 120 days after planting. 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. China Agricultural Press, Beijing, Wei YX, Ru C, Wu Y et al (2019) Response of photosynthate production characteristics of rice to water consumption process in black soil region. 1. A tiller number is the key determinant of rice plant architecture and panicle number and consequently controls grain yield. Thus, it is necessary to optimize the tiller number to achieve the maximum yield in rice. This work was jointly supported by the National Natural Science Foundation of China (51779046, 51809042). The cultivars Kuttusan and Orkazhama ranked second and third. Chhattisgarh is known as the rice bowl of the country. (2019) 129 sativa check. Agric Res (2020). The tiller number at different development stages and heading traits involved in phase transitions were evaluated. 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. 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). The higher grain yield of Uraibuta (580.66) and Banspor (491.6) under rainfed site can be related with maintenance of high leaf water status, spikelet fertility and photosynthetic stability whereas lower yield of Luchai (185.3) under water limiting condition can be associated with low photosynthetic stability and low percent of filled grains. Thus, it is necessary to optimize the tiller number to achieve the maximum yield in rice. Access scientific knowledge from anywhere. Multiple linear regression models of lead SNPs showed coefficients of determination (R 2) 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. 1.1 Rice Crop Tillers & Panicle 1. 1. Part of Springer Nature. Effective Tiller Numbers, Photosynthetic and Yield Response of Rice (Oryza sativa) to Shallow Wet–Dry Irrigation Water Controlled at Tillering Stage in Black Soil Area. 1.1 Rice Crop Tillers & Panicle This research would focus on phenotyping of rice crops. 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. germination (anaerobic germination ability; AG), submergence and stagnant flooding stresses. 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 … An experiment was carried out presently to analyze the variation of accumulation of phenolics in some native rice cultivars of North Kerala, India in response to salt stress. 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. Each tiller will bear a rice panicle, and you can get up to 100 grains of rice per panicle. Chin Agric Sci Bull 24(2):160–166, Wang CC, Kong LL, Li MJ et al (2015) Effect of water treatments at tillering stage on super rice yield and physiological characteristics. 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 the grain-bearing part of rice crops and it possesses the leaves [4]. Feng, Z., QI, Z., Zhang, Z. et al. Science of the Rice Plant). 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 … The difference in effective tillers/hill is due to the genetic makeup of the rice varieties. Dept. A novel and major QTL for the effective tiller number was identified on chromosomal arm 1BL and validated in two genetic backgrounds The effective tiller number (ETN) substantially influences plant architecture and the wheat yield improvement. Flooding is an important abiotic stress affecting rice production in rainfed lowlands of Asia and Africa. More effective tillers per plant are believed to be closely associated with high seed yield per plant resulting high productivity. Rice is the world's leading food crop, cultivated over an area of about 145 million hectares. 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. 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 the tiller number prediction. 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. The hybrids, L3 x T1, L3 x T3, L1 x T2, L6 x T2 and L7 x T1 had significantly high sca effects for maximum number of traits. Field Crops Res 233:70–79, Article  From the main stem, another stem would develop. The numbers of effective tillers per plant differed between years, varieties, and irrigation (data not presented). which is distinct from the lateral branching of dicotyledonous plants. 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. 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. Therefore, the study can provide the theoretical basis and reference for water-saving and high yield of rice in black soil region. The whole plant will become bluish green in colour. ... Foliar application of fertilizers is yet another means to increase the fertiliser use efficiency in rice crop. (2008) and Chowdhury et al. The maximum number of tillers usually occurred at the late tillering or jointing stage (approximately 40 DAT). Rice can be grown in different environmental conditions, but wetland cultivation is the most widely used method for rice production.

Stem rot incidence and severity increase as stand densities are increased; thus, avoid rice stands that are too dense. The first tiller usually emerges when the seedling has five leaves. Oxidative stress is one consequence of salinity that may be responsible for much of the damage. Tillers from the rice plant emerge in a specific chronological sequence and it mainly depends on its duration and morphology. • Conversely, the other components like effective tiller number and grain weight are under genetic control. Farmers look for pest symptoms in rice tillers. IV). The hybrids were evaluated for their extent of heterosis on the basis of commercially exploitable standard heterosis for yield traits. Genotypes found in cluster VI was the highest yielder (5304 kg/ha) followed by cluster IV (4189 kg/ha) and Cluster III (3278 kg/ha). III. Abstract. A tiller is a stem produced by grass plants, and refers to all shoots that grow after the initial parent shoot grows from a seed. The lowest number of effective tillers/hill (5.95) was recorded in Raniselute. 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 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. (1993) who stated that effective tillers/hill varied with their vari-ety. It was inferred from the studies that cross combinations viz., L2 x T3, L3 x T1, L3 x T3, L4 x T1, L4 x T3, L4 x T4, L5 x T1, L5 x T2, L6 x T2, L8 x T2 and L9 x T4 expressed significantly superior heterosis percent for most of the characters including single plant yield. Trans Chin Soc Agric Eng 34(3):143–150, Zhao LM, Li M, Zheng DF et al (2014) Analysis of the factors and their effect on the photosynthesis of rice. In the preliminary screenings, most of the O. glaberrima accessions were found to have good levels of anaerobic germination ability and stagnant flooding tolerance but were sensitive to submergence stress. The conventional method of manually counting tillers is labor intensive and time-consuming, which is not feasible for modern rice breeding trials that involve hundreds of new cultivars (Kakar et al., 2019). 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. However, the availability of asparagine generated from AS1 reactions is apparently less effective for the outgrowth of tillers.

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. 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 ). PubMed Google Scholar. Differences in grain yield and yield components had a reduced number of effective tillers (reduced by 1% 29%) (Table S1, Figures 1H, S3A, S4–7E). Subscription will auto renew annually. found that nitrogen fertilizer application increased the number of rice tillers, but not every tiller contributed equally to the overall yield. For each rice pest, farmers have their own economic injury levels. This signifies the start of the tillering stage. Complex and ecologically responsive rice-fish farming systems have evolved in the coastal wetland regions of India over centuries. FOR TOLERANCE TO ABIOTIC STRESS. Gramineous plants have a special type of side shoot referred to as a tiller. Abstract. Method to increase effective tillers in Paddy by SherGill Markhai - Duration: 5:38.

Amino acid transporters (AATs) play indispensable roles in nutrient allocation during plant development. Yield Attributing Characters of Rice Number of effective tiller per square meter The number of effective tillers per m 2 was calculated for each plot just before harvesting the crop. Tiller Angle Control 1 (TAC1) is a key regulator responsible for the different tiller angles between japonica and indica rice. This type is good for northern areas and can withstand a light frost. 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 radiation, changed along with that of the LAI [ 19 ]. square foot), rice plants generally produce 2 to 5 panicle bearing tillers per plant compared to 10 to 30 tillers per plant in transplanted rice where more space is available between plants.

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. Grain yield is a complex character and its expression under specific environment depends on one or more of yield components. of Agronomy. secondary and tertiary tillers which come forth at different stages of growth. Kaippad is such an indigenous rice-fish farming system of coastal North Kerala in India. Because of these relationships, the leaf number concept provides researchers with an effective index for studying development of shoot and root systems in rice, including the prediction of tiller morphology, the estimation of potential tiller increase, and analysis of root system dynamics.
