Abstract:

The present study was undertaken on twenty-nine genotypes of rice to determine, genetic variability, the nature of association among different yield attributes and their direct and indirect contribution towards yield. A high degree of variation was observed for all characters studied. Estimates of PCV and GCV were higher for the number of effective tillers per plant, flag leaf area, yields per plant and for test weight. Small differences between GCV and PCV were recorded for all the characters studied which indicated less influence of environment on these characters.The presence of high heritability with high genetic advance showed additive effects of the gene on the character and theyresponse to selection effectively as they are least affected by the environmental condition. Grain yield per plant showed the significant positive correlation number of effective tillers per plant, panicle length and test weight. The result of path analysis indicated number of effective tillers per plant had a highest positive direct effect on grain yield per plant followed by flag leaf area, days to maturity, panicle length and leaf length.
