ASSESSMENT OF GENETIC DIVERSITY IN PUMMELO (CITRUS MAXIMA (BURM.) MERR.) ACCESSIONS IN VIETNAM BY UTILIZING SIMPLE SEQUENCE REPEAT (SSR) MARKERS

Abstract

Genetic relationships among 15 pummelo (Citrus maxima (Burm.) Merr.) accessions collected from different areas of Vietnam have been investigated by using ADN-based simple sequence repeat (SSR) markers. A total of 18 SSR primers have been individually amplified to allow the differentiation of materials. The polymorphisms (83.33%) were obtained by simple sequence repeats (SSRs). The mean polymorphic information content (PIC) for each of these marker systems has been 0.44, which has suggested that all the marker systems have been effective in determining polymorphisms. The UPGMA dendrogram which has been constructed by using data of tow marker systems has separated the genotypes into four main clusters. These results have supported that germplasm studies have indicated a considerable
