the objectives of the present study were to evaluate spring wheat recombinant inbred lines (rils) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (pca) for spot blotch resistance and yield components at bhu agricultural research farm during 2010-2011. grain yield per plot was significantly and positi...

Environmental sustainability concerns make improving yield under lower N input a desirable breeding goal. To evaluate genetic variation and heterosis for low-N tolerance breeding, 28 F1 hybrids from a diallel scheme, along with their eight parental lines, were tested for agronomic traits including kernel number per ear (KNE) and grain yield per plant (GY), in replicated plots over two years und...

Selecting and cultivating the crops/varieties that can tolerate water salinity is potentially animportant strategy to save fresh water resources and maximize the crop yield in salt affected areas.To evaluate the responses of 36 sorghum lines and cultivars to salinity stress, two fieldexperiments were conducted in non-stress (EC=2 dS/m) and salinity stress conditions (EC=12dS/m) using randomized...

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...

this study was carried out to purify chitti bean cultivars. in the first year, 11 populations were collected from main chitti bean cultivating areas. based on some criteria such as higher yield, earlier maturity, more pods and tolerance to pests and diseases, single plants were selected. in the second year, seeds of each selected single plant as well as controls (talash and cos16) were managed ...

The present investigation Comprises 34 advanced breeding lines including checks of bread wheat and experiment was conducted in a complete randomized block design with three replications at the research farm department genetics plant breeding, RVSKVV, B.M. College Agriculture, Khandwa during Rabi season (November 2021 to April 2022) for estimation multivariate analysis divergence. were grouped i...

Chromosome segment substitution lines (CSSLs) are rich genetic resources that can be mined for novel, agriculturally useful loci or that can be used directly as materials for breeding. To date, a number of rice CSSLs have been developed by crossing rice cultivars with its wild relatives as a means to tap into the potential of wild alleles in rice improvement. Oryza nivara is a wild relative of ...
