Studies on Characters Association and Path Analysis for Seed Yield and its Components in Pigeonpea ( Cajanus cajan (L.) Millsp.)

The estimates of genotypic correlation coefficients in general were higher than their corresponding phenotypic correlation coefficients indicating strong inherent association among the traits. The seed yield per plant had significant and positive association with days to 50% flowering, days to maturity, number of branches per plant, number of pods per plant and 100-seed weight at both genotypic as well as phenotypic levels. Characters like 100-seed weight, days to maturity and pod length exerted high direct effects on seed yield. 100-seed weight and days to maturity also contributed indirectly towards seed yield per plant through most of the characters. Thus, based on present study days to maturity, numbers of pods per plant and 100-seed weight were emerged as the most important components of seed yield.
