Association Analysis for Yield and its Component Traits in F3 and F4 Populations of Pigeonpea (Cajanus cajan (L.) mill Sp.)

An investigation was carried out in pigeon pea to understand the association among the yield components and their direct and indirect effects on the seed yield. Character association studies indicated that days to maturity, number of seeds per plant, number of pods per plant, test weight (gm), seed yield per plant (gm) shows significant positive correlation with seed yield per plant at genotypic and phenotypic level in F 3 and F 4 generation. Path coefficient analysis revealed that number of seeds per pod, number of pod per plant and test weight (gm) were the most important character which can be strategically used to improve yield in Pigeon pea.
