 ABSTRACT

The present investigation was carried out to determine the relationship and genetic diversity among sixty greengram germplasm accessions using principal component for various morphological traits. In this study, Component 1 had the contribution from the traits viz., pod length, 100-seed weight and number of primery branches which accounted 21.64% to the total variability. Number of pods per cluster, number of pods per plant, number of seeds per pod and seed yield per plant has contributed 17.65% to the total variability in component 2. The remaining variability of 11.48%, 11.08%, 9.30% and 7.63% was console dated in component 3, component 4 and component 5 by various traits viz., Days to 50 flowering, Plant height, Number of pods per  cluster, number of pods per plant, number of seeds per pod and seed yield per plant . The cumulative variance of 71.07% of total variation among eleven characters was explained by the first five axes. Thus the results of principal component analysis revealed, wide genetic variability exists in this greengram germplasm accessions.

Key words: Principal component analysis, Greengram, Genetic diversity.
