Abstract
In order to promote the preservation and breed improvement of radish germplasm resources, nine varieties of radish were used as the experimental materials, which tried to study on genetic diversity the local and conventional radish varieties mentioned above using SSR. Firstly, field characters (leaf shape and skin color) of the above radish materials were observed, then, 9 pairs of SSR primers were screened to detect the above radish samples. The genetic diversity of nine radish species was analyzed by electrophoretic banding and NTSYS software. The results showed that the nine varieties of radish were divided into two groups, group 1 includes 8 varieties except Qiyehong radish, and each variety showed diversity among different similarity coefficients, group 2 includes only Qiyehong radish. There were two distinct branches in the first group, one branch includes four radishes, Lixiangdagen radish, 734 radish, General radish, and Huangzhou radish, whose skin color is white; another branch includes four radishes, the Yichihong radish, Hongbao radish, 262 radish, and Red garden radish, whose skin color is red, which was consistent with field observations.关键词
