| description | For designing of the breeding programme, analysis of genetic variability and character correlation is crucial in crop
improvement. The aim of this experiment was to estimate genetic variability parameters and trait association for 13
quantitative traits which were measured in F2 segregating populations of six crosses containing nine parents. All the F2
populations showed significant GCV and PCV values for productive tillers per plant, grains per panicle, grain yield per
plant and straw yield per plant, indicating that these traits may be improved through selection. Plant height, productive
tillers per plant, grains per panicle, grain yield per plant and straw yield per plant showed high heritability coupled with
high genetic advance, indicating that these traits were controlled by additive gene action and have a good chance of
improvement through pure line selection. Grain yield per plant exhibited a strong positive correlation with plant height,
panicle length, grains per panicle, straw yield per plant, productive tillers per plant and harvest index in all the six F2
segregating populations. The F2 population of the cross GR 17 × NVSR 2740 demonstrated that more GCV and PCV,
high heritability with high genetic advance for the majority of the traits which can be improved by selection. |
