Abstract: In the present study, one hundred and fifty-one genotypes of adzuki bean were assessed at the experimental farm of the Department of Organic Agriculture, CSKHPKV, Palampur in Augmented design during Kharif, 2019 to estimate the extent of association, direct and indirect effects of the characters on yield and its component traits. Analysis of variance revealed that mean sum of squares due to treatments were significant for all the traits under study except plant height. Correlation studies showed that seed yield had significant positive correlation with days to 80% maturity, primary branches per plant, seeds per pod and pods per plant while, Path studies revealed that primary branches per plant, seeds per pod, pods per plant and days to 80% maturity have high direct effects on yield. Principal component analysis (PCA) indicated that first four PCs contributed 60.78% to the total variability for ten agronomic traits. First PC (F1) contributed maximum towards the variability (23.64%) followed by F2 (14.94%), F3 (11.84%) and F4 (10.36). Sufficient amount of variation was observed in the genotypes based on parameters of variability, principal component analysis, correlation and path analysis which could be utilized by researchers in various breeding programme of this crop.
