Abstract

Correlation between yield and yield attribute component traits in ninety three genotypes of pigeon pea revealed that single plant yield had positive and highly significant association with pod weight per plant, number of pods per plant and shelling percentage. The selection criteria can be done based on these characters for seed yield will give successful results for yield improvement in pigeon pea. Path coefficient analysis of different traits on single plant yield recorded that traits viz., pod weight per plant, number of pods per plant and shelling percentage showed highest positive direct effect. Hence selection on these studied characters might be useful in Pigeon pea yield improvement.
