Analysis of Genetic Diversity of Indonesia Rodent Tuber (<i>Typhonium flagelliforme</i> Lodd.) Cultivars Based on RAPD Marker


Rodent tuber (Typhonium flagelliforme Lodd.) is a plant from Araceae family. The plant has high medical potential as anti-cancer agent. The information regarding Indonesian rodent tuber’s genetic diversity is not available yet. Genetic information is very important for the development of rodent tuber as medicinal plant. In this research, genetic diversity and genetic distance of three Indonesian rodent tuber’s cultivars, from Bogor, Pekalongan, and Medan, were analyzed by using RAPD molecular markers. The data obtained was analyzed by NTsys software. Out of 16 primers used in the study, the 12 primers were found to be polymorphic. There were 83 bands of DNA obtained and 31 of them were polymorphic. Dendogram analysis of the three rodent tuber cultivars showed that these cultivars were clustered into two clusters. The first cluster consists of rodent tuber Bogor and Medan. The second cluster consists of rodent tuber Pekalongan. The coefficient of similarity ranged from 0.81 to 0.87. The highest coefficient of similarity was 0.87, which was detected between rodent tuber Pekalongan and Medan. The lowest coefficient of similarity was 0.81, which was detected between rodent tuber Bogor and Pekalongan. Among these three cultivars of rodent tuber, cultivar Bogor was exclusively different.
