Abstract

The genetic diversity of 60 glutinous rice accessions of Assam was analyzed using 17 RAPD primers. Out of the 160 reproducible bands, 145 found to be polymorphic. The number of polymorphic bands ranged from 4 (OPL-17) to 18 (OPB-07). With an average of 88.75% polymorphism between the accessions, a high degree of molecular variation was detected in the rice collection. The average Jaccard's similarity co-efficient based on RAPD data was found to be 0.446, indicating a high level of diversity in the glutinous rice of Assam. The cluster analys is grouped the accessions in to nine sub clusters. Implications of these findings in indigenous glutinous rice conservation and improvement are discussed.
