Studies on Correlation and Path Coefficient Analysis for Yield and Yield Contributing Characters in Pigeonpea [Cajanus cajan (L). Millips]

Abstract

Correlation between yield and yield attribute component traits in forty two genotypes of pigeonpea revealed that seed yield per plant had positive and highly significant association with number of pods per plant, number of secondary branches per plant, plant height, number of seeds per pod and days to maturity. Selection criterion can be done based on these characters for seed yield will give successful for yield improvement in pigeonpea. Path coefficient analysis of different traits on seed yield per plant recorded that traits viz., number of secondary branches per plant, 100 seed weight, number of seeds per pod, plant height and number of primary branches per plant showed highest positive direct effect. Hence selection on these studied characters might be useful in pigeonpea yield improvement.
