In the present study, PCA performed for phenological and yield component traits revealed that out of sixteen, only four principal components (PCs) exhibited more than 1.00 eigen value, and showed about 74.79 % total variability among the traits studied under stress condition while under normal condition out of sixteen, only five principal components (PCs) exhibited more than 1.00 eigen value and showed about 77.84% variability among the traits studied. Scree plot explained the percentage of variance associated with each principal component obtained by drawing a graph between eigen values and principal component numbers. |
