Abstract: Evaluation of rice genetic diversity is an important step for character specific varietal development program. The present study characterizes 15 rice germplasm of Indian accessions on the basis of agro morphological, physicochemical and cooking parameters. The cultivars showed high degree of variations on their traits. Mean plant height of 88.96 cm, flag leaf length (26.48 cm), flag leaf width (1.17 cm), grain per panicle (130), panicle length (20.97 cm), days to 50% flowering (112.06 days), kernel length breadth ratio (2.65), cooked kernel length breadth ratio (3.25), linear elongation ratio (1.65). Out of 15 rice cultivars, only Sada nunia and Das nunia are aromatic rice and Sada nunia also contain awn. Plant height showed significant positive correlation with PnL and DF and significant negative correlation with GB. GL positively significantly correlates with FLL, GrWt with GL and GB, DF with MT. The cluster analysis grouped the 15 cultivars into 4 clusters with 37.5 dissimilarity coefficient. The high variability with promising traits among the cultivars expected to be significance for future rice breeding programmes.
