摘要：

This study evaluated the genetic variability of 34 local rice genotypes from Simeulue Island and Sumba Island, Indonesia, using ISSR and SRAP mark-ers. The amplification of ISSR and SRAP primers produced high percentages of polymorphism, with values of 98.17% and 99.75%, respectively. The result of the UPGMA dendrogram analysis classified the rice genotypes into three groups by ISSR and two groups by SRAP. The ISSR had a higher Resolving Power (RP = 14.66) and Marker Index (MI = 4.61) than the SRAP (RP = 9.13, MI = 3.8). How-ever, the results of the UPGMA dendrogram corresponded to the STRUCTURAL data analysis. The Delta K of STRUCTURAL analysis performed its maximum value when K = 3 by ISSR and K = 2 by SRAP. This study pointed out that ISSR markers were more effective than SRAP markers in evaluating the degree of genetic variability of rice genotypes.
