Diversity and Population Structure of Local Rice Varieties from Indonesia Revealed by SSR Markers

Indonesia's local rice varieties (Oryza sativa L.) have a wide range of diversity that can be valuable sources for crop improvement with molecular markers. This study investigated varieties' genetic and population structure using simple sequence repeat (SSR) The SSR markers demonstrated their informativeness genotypic characterization as represented by the gene indices polymorphic information content. UPGMA dendrogram divided 63 into two distinct clusters different levels sub-grouping tendency according to origins, supported PCoA. In contrast, PCA these agro-morphological traits was scattered in all quadrants. Thus, DNA level variation analyzed seems complement phenotypic traits, which were not well structured revealed significant among varieties, within, populations (P<0.01). pattern grouping analysis total subpopulations is similar but better resembles pedigree set varieties. These findings implied importance breeding improvement, maintenance, management resources Indonesia.
