Abstract

Persimmon (Diospyros L.) is an economically important fruit in the world, and it has been recognized as a healthy nutrient supply for human consumption. In this study, 14 microsatellite markers were developed from an AG/TC and AC/TG-enriched genomic library of Chinese persimmon Mopanshi. Twelve polymorphic markers were selected in 4 related species; these markers showed transferability to the 4 related persimmon species. In addition, 10 simple sequence repeat (SSR) markers were used to detect the genetic diversity among 51 persimmon accessions from China, Japan, and Korea. A total of 57 polymorphic bands with an average of 5.7 bands per primer pair were observed. According to cluster analysis and principal coordinate analysis, all persimmon accessions could be divided into 4 groups. A close relationship existed between D. kaki and D. oleifera, and D. glaucifolia and D. lotus. Jinzaoshi could be considered a separate species of persimmon. These new SSR markers provide tools for evaluating genetic relatedness among different persimmon species.
