In Indonesia, soybean is an important crop plant after rice and corn. There are various local soybean cultivars, among them are Burangrang, Gema, Grobogan, Panderman, and Sinabung. Molecular analysis on various soybean cultivars is beneficial for soybean breeding. Analysis by SSR technique could reveal genetic relationship among cultivars studied. This study objectives were to obtain the SSR profiles of the five soybean cultivars, and to examine as of how the cultivars were grouped based on the SSR markers. The results showed that the five soybean cultivars separated into two main clusters. Cultivars of Gema, Burangrang, and Grobogan were in one cluster, while Panderman and Sinabung were grouped in another cluster. Furthermore, the first cluster consists of two sub-clusters, where Grobogan forms one sub-cluster separated from the second sub-cluster consisting of Gema and Burangrang. This grouping was relevant to salinity resistant characteristics of the cultivars studied.
