Thirty eight rice accessions were analyzed to evaluate the genetic polymorphism and identification of diverse parents using simple sequences repeat (SSR) markers. These accessions showed significant phenotypic variation for all the characters studied. A total of 61 alleles were detected by 11 polymorphic markers showing highly polymorphic across all accessions with an average of 5.54 alleles per polymorphic marker. Five of the markers RM324, RM171, RM31, RM24, RM30 produced maximum 6 alleles. The PIC value ranged from 0.275 to 0.751 with a mean PIC of 0.633 and Markers RM31, RM336, RM30 and RM280 were the most informative primers to discriminate among the accessions on the basis of highest PIC of 0.751, 0.735, 0.731 and 0.719, respectively. The cluster analysis showed that these accessions grouped in to seven clusters in which cluster IIB had maximum 8 genotypes followed by cluster IA-1 (7 germplasms) and cluster IA-2 (6 germplasms). While, highest dissimilarity coefficient value was observed between the cultivar cultivar C-3 and LAL KHADHA. These accessions were showing wide genetic divergence among the constituent in it and may be directly utilized in hybridization programme for improvement of yield related traits.
