Estimation of Genetic Parameters, Correlation and Path Analysisin Advance Lines of Pigeonpea [Cajanus cajan (L.) Millspaugh.]
An experiment comprising of fifteen genotypes of pigeonpea was conducted during kharif 2019 to study the genetic variability, correlation and path coefficient analysis. The highest GCV was recorded for the number of pods/plant followed by seed yield/plant. High Heritability was observed for 100-seed weight (96.88%) followed by Days to flowering (91.07%) and days to maturity (90.28%). High estimates of genetic advance as percent of mean was recorded for number of pods/plant and 100-seed weight. Correlation studies revealed Pods/plant, Branches/plant are positively and significantly correlated with yield/plant. The path coefficient analysis indicated that characters viz. Days to maturity, pods/plant and 100-seed weight have direct effect on seed yield. Hence branches/plant, pods/plant, 100-seed weight should be considered during selection in yield improvement programme.
