 ABSTRACT

Correlation coefficient and path analysis were studied for seed yield and yield attributing traits in pigeonpea [Cajanus cajan (L.) Millsp.]. The present investigation was conducted during the kharif season 2014 and 2015. Twelve promising genotypes along with two checks i.e. Manak and Paras were evaluated for yield and yield attributing traits. There was significant variation observed for all the characters under study. Seed yield per plant was found to be significantly positively associated with number of pods per plant at both genotypic and phenotypic level, days to 50% flowering, days to maturity and 100 seed weight at genotypic level only. Path coefficient analysis (genotypic and phenotypic) showed that number of primary branches exhibited the highest genotypic magnitude on seed yield/plant, followed by days to 50% flowering and plant height.

Key words: Pigeonpea, correlation coefficient, yield and path coefficient.
