Genetic analysis of yield and its component traits in drought tolerant genotypes of pigeonpea (Cajanus cajan L. Millspaugh)

In the present investigation, sufficient variability was observed in the drought tolerant pigeonpea genotypes for the traits under study. Most of the yield contributing characters showed significant positive correlation whereas, number of primary branches per plant showed significant negative correlation with seed yield. Days to maturity had maximum direct effect on seed yield followed by number of pods per plant and plant height and number of secondary branches which had negative direct effect on seed yield. Number of secondary branches per plant, number of pods per plant and days to maturity were identified as important yield components and hence, selection should be focused on these traits to improve yield in drought tolerant genotypes of pigeonpea.
