Abstract:

The experiment was conducted in randomized block design replicated thrice, for the evaluation of thirteen quantitative traits in twenty rice genotypes. Significant difference for all the quantitative traits was observed among the genotypes indicating presence of variability and scope of selection. Higher estimates of phenotypic coefficient of variation (PCV) than genotypic coefficient of variation (GCV) for all the traits reflected influence of environmental factor on these traits with variable influence. The characters fertile spikelet per panicles, Test weight, yield per plant, harvest index, Biological yield per plant and flag leaf width showed greater influence of environment reflecting scope of improvement of these traits by providing favourable environment whereas least influenced traits cannot be improved even in favourable condition but may be good for selection. The traits plant height, effective tillers per plant, flag leaf length, test weight and biological yield per plant showed high estimates of heritability and genetic advance implies additive genetic component and can be used for selection in early segregating generations. Considering both correlation and path study the traits Panicle length, biological yield per plant, harvest index and test weight showed true association with grain yield per plant having significant and positive correlation with high positive direct effect. Hence for implication of direct selection these traits should be considered.
