Genetic Diversity of a Natural Population of Akebia trifoliata (Thunb.) Koidz and Extraction of a Core Collection Using Simple Sequence Repeat Markers

Understand genetic diversity and structure of germplasm is premise conservation utilization. And core collection can reduce the cost difficulty conservation. Akebia trifoliata (Thunb.) Koidz an important medicinal, fruit oil crop, particularly in China. In this study, 28 simple sequence repeat (SSR) markers were used to assess 955 A. germplasms, determine their molecular identity extract a collection. The germplasms was moderately polymorphic. average number alleles (Na), observed heterozygosity (H O ), expected E Shannon’s information index (I ? polymorphic content (PIC) 3.71, 0.24, 0.46, 0.81, 0.41, respectively. Four subpopulations identified, indicating weak structure. A could be completely distinguished by characters s28, s25, s74, s89, s68, s30, s13, s100, s72, s77, s3. each germplasm’s made up eleven characters. composed 164 (17.2% total population) parameters differed significantly from those random These results have implications for At same time, based on results, better managed.
