Genetic diversity of 94 japonica rice was assessed using 81 simple sequence repeat (SSR). All 81 SSR markers generated a total of 351 alleles. The number of alleles ranged from 1 to 16 with a mean of 4.3 alleles per SSR marker. Six of 81 SSR markers showed monomorphic bands in 94 japonica rice. But several SSR markers on chromosomes 4, 9, 10 and 11 produced many alleles within the japonica rice. Japonica rice could be classified into six major groups by the clustering analysis based on 81 SSR markers.
