Abstract

In the present investigation, high heritability accompanied with high GA as per cent of mean was observed for the characters - days to fifty per cent flowering, plant height, leaves per plant, leaf length, earhead weight, number of primaries per panicle, 100 grain weight, grainmould score and single plant yield thus suggesting that these characters are under additive gene action and thus gives better scope for selection. Seed yield was positively and significantly correlated with days to maturity, number of leaves per plant, earhead weight and number of primaries per panicle but there was negative significant correlation with grainmould score. The characters number of leaves per plant, earhead length, earhead weight, number of primaries per panicle and grainmould score showed positive direct effect on seed yield. From the present study, it is clear that the direct and indirect effects among the component viz., panicle weight and number of primaries per panicle were positive and improvement of any of these traits will simultaneously improve the seed yield.
