Correlation and Path Analysis: for Seed Yield and Yield Contributing Characters in Pigeonpea

An investigation on correction and path analysis in redgram was carried to elicit the information on nature and extent of the genetic variability, heritability, genetic advance, character association and path analysis. Observations were recorded on thirteen characters. The analysis of variance indicated significant difference among the genotypes for all the 13 characters studied. The genotypic coefficient of variation for all the characters studied were lesser than the phenotypic coefficient of variation indicating masking effects of the environment. Character association studies and Path coefficient analysis revealed significant and positive correlation of seed yield per plant with number of secondary branches per plant, number of pods per plant, dry matter content per plant and harvest index and simultaneous improvement of these characters along with seed yield is possible.
