Abstract
Thirty genotypes of greengram including 22 mutant lines, two parents and two standard varieties along with four land races were evaluated in R.B.D. for yield and component traits. The PCV and GCV estimates were high for response to cold of 10, 30 and 40 days old seedlings of green gram at 10 oC temperature. Plant height and pods plant -1 had high heritability with high genetic advance indicating additive gene action. Characters like100-seed weight and seed pod -1 were with high-moderate heritability but low genetic advance indicating non-additive gene effect. Plant height, cluster plant -1 , Pods plant -1 , pod length and seeds pod -1 showed significant positive correlation with yield. Path-analysis showed that pods plant -1 had highest direct positive effects on yield followed by plant height. Positive correlation of most traits with yield was greatly influenced by indirect positive effect via pods plant -1 and plant height.
