Abstract

A 7 parent diallel analysis was conducted to estimate combining ability and gene action in some tall and dwarf genotypes in pea. The results indicated that both gca and sea variances were equally important for the yield attributing traits. This indicates the prevalence of both additive and non-additive variance for plant height, number of branches/plant, and seeds/pod. For days to flowering, days to maturity, pods/plant, and seed yield/plant, nop~additive gene action was predominant. For 100-seed weight, additive genetic variance was more important. Estimates of gca effects indicated that among tall genotypes KPMR-327 and KPMR-288 proved to be good combiner for yield traits. Among dwarf genotypes, NDP-93 and KFPD-59 were good general combiners. Crosses involving tall and dwarf parents such as KPMR-288, KfED-59 and HUP-15, KPMR-327 had high sea effects.
