Given the urgency of rising sea levels and need to sustain food production, developing flood-tolerant crops is essential. The aim this study was assess genetic potential cross CO51x13-6 (NIL CO43Sub1) in BC2F4 BC2F5 generations using Parent Offspring regression analysis. Significant variation observed across a wide range traits both generations. distribution important traits, including plant he...

This experiment was conducted to study the variability parameters of forty rice genotypes evaluate genetic i.e., Genotypic coefficient (GVC), Phenotypic (PVC), Heritability (H) and mean percent Genetic advance (MGA) for nine different yield yield-contributing traits at Agriculture Research Farm, Banaras Hindu University, Varanasi during Kharif-2018. The data were collected attributing subjected...

Wild diploid wheat Aegilops tauschii, the D-genome progenitor of common wheat, carries large genetic variation in spikelet and grain morphology. Two differentiated subspecies of Ae. tauschii, subspecies tauschii and strangulata, have been traditionally defined based on differences in spikelet morphology. Here, we first assessed six spikelet shape-related traits among 199 Ae. tauschii accessions...

The architecture of maize inflorescences, the male tassel and the female ear, is defined by a series of reiterative branching events. The inflorescence meristem initiates spikelet pair meristems. These in turn initiate spikelet meristems which finally produce the floret meristems. After initiating one meristem, the spikelet pair and spikelet meristem convert into spikelet and floret meristems, ...

Water deficit caused a serious threat to crops, especially panicle development at reproductive growth phase. We investigated grain yield components and gene expression profiles of panicle among tolerant and sensitive rice in response to drought stress. Panicle morphologies exhibited that secondary branches per panicle were more severely affected as compared to primary branches per panicle. More...

308 The variability in the breeding material is extremely important in the selection of superior type plant, where selection is based not only on yield but also on its component traits. Such information on segregating population, where selection is actually practiced, will be more meaningful and of immediate practical utility. Moreover, most of the yield component traits are quantitative in nat...

Sewage sludge at the rate of 0, 40, 80, 120 and 240 t/ha showed that the number of filled grains per panicle, dry weight of grains and weight of 1000 grains of rice (Oryza sativa L.) were the significantly highest where 240 tons of sewage sludge per hectare was added. The contents of N, P, K, Ca, Mg, Fe, Cu, Zn and Pb in rice grains increased significantly with increasing rate of sewage sludge ...

Meristems may be determinate or indeterminate. In maize, the indeterminate inflorescence meristem produces three types of determinate meristems: spikelet pair, spikelet and floral meristems. These meristems are defined by their position and their products. We have discovered a gene in maize, indeterminate floral apex1 (ifa1) that regulates meristem determinacy. The defect found in ifa1 mutants ...

Panicle length (PL) is an important trait for improving panicle architecture and grain yield in rice (Oryza sativa L.). Three populations were used to identify QTLs and candidate genes associated with PL. Four QTLs for PL were detected on chromosomes 4, 6, and 9 through linkage mapping in the recombinant inbred line population derived from a cross between the cultivars Xiushui79 (short panicle)...
