Abstract
Genotypic and phenotypic coefficients of variation heritability, expected genetic advance,correlation and path analysis for yield and yield contributing traits were estimated using 27accessions of pigeonpea. Moderate to high PCV and GCV were recorded for number of pods,seed yield per plant, plant height and plant spread. High heritability with high genetic advanceas % of mean was observed for number of pods, primary and secondary branches per plant, testweight, plant height and plant spread. Days to 50% flowering, plant spread, primary and secondarybranches per plant, number of pods and raceme length had moderate to low direct effect and itstrue relationship of these traits with grain yield. Hence, direct selection for these traits would berewarding for yield improvement in pigeonpea.
Keywords
