In this study we evaluate the informative and efficiency of Simple Sequence Repeat (SSR) and Sequence Specific Amplified Polymorphism (SSAP) markers for genetic diversity, genetic relationship and population structure among 87 super sweet corn inbred lines generated by different origins. The SSR showed relatively higher level of the average gene diversity and shannon’s information index value than that of the SSAP. To assess genetic relationship and to characterize among 87 super sweet corn inbred lines using the SSR and SSAP markers. The dendrogram using SSR marker divided into nine groups of clusters were observed at the genetic similarity value 53.0%. For SSAP marker, Total three main clusters were confirmed in genetic similarity value at 50.8%. Result of combine data for SSR and SSAP markers showed six subgroup were detected in genetic similarity at 53.5%. To confirm population structure, the total 87 super sweet corn inbred lines were divided into groups I, II and admixed group based on membership probability 0.8 for SSR and SSAP markers. However population structure using combine data was K=3 and divided into group I, II, III and admixed group. This study has demonstrated the comparative analysis of SSR and SSAP for the study of genetic diversity and the genetic relationship for super sweet corn inbred lines. Thus, the results of this study will be useful to maize breeding programs in Korea.
