Abstract

Significant differences were observed among F2 population of six single crosses and parents for
all characters. Plant height, number of secondary branches per plant, number of mature pods per
plant, pod yield per plant, kernel yield per plant, haulms yield per plant and harvest index showed
high estimates of GCV and PCV, heritability (broad sense) and GAM. The role of additive gene
action seems to be significant in the inheritance of these traits. Pod yield showed highly significant
positive association with number of mature pods per plant (0.541), SCMR (0.588), kernel yield per
plant (0.981), pod width (0.682) and harvest index. Improvement in pod yield could be brought
by selection for characters viz., number of mature pods, kernel yield, pod width, SCMR and
harvest index.
