Abstract: Principal component analysis was carried out to determine the variation in seed vigour characters among the fifty traditional aromatic rice genotypes. The wide range was observed for the root length (35.5-162.2 mm) followed by shoot length (70.9 -125.9 mm) and germination % (62.5-100%). The vigour index showed highly significant positive correlations to seed length (r = 0.489), 1000 seed weight (r =0.596), germination % (r =0.460), shoot length (r =0.539), root length (r = 0.686) and shoot dry weight (r =0.572). Out of eight, first three components exhibited more than one eigen value and showed 79.89 % of the total variation among the traits studied for each genotypes. The PC1 had 50.794 %, PC2 showed 16.571% and PC3 exhibited 12.525% variability among the genotypes for the traits under study. It also identified the 1000 seed weight, shoot dry weight, seed length and germination percentage as the characters contributing most of the variation.
