COMBINING ABILITY FOR YIELD AND ITS COMPONENTS IN MUNGBEAN (Vigna radiata L. Wilczek)

Abstract

Combining ability studies were carried out through a 8 x 8 half diallel set for seed yield and its components. Variance due to general and specific combining ability was significant for all the characters. Additive gene effect was observed for all the characters except seed yield per plant E-65 and TARM-18 for earliness and days to maturity, WGG- 37 for clusters plant.BM-4 for pods in plants and pods in cluster, KDM-1 for 100 seed weight and Kopergaon and JLM-5 for seed yield in plant were found as best combiners. The cross. Kopergaon x E-65 showed highly significant positive SCA effects for plants height.pods in cluster and seed yield per plant.
