Genetic Diversity Analysis of Seed Appearance Quality of Chinese Soybean Mini Core Collection

AbstractThe appearance quality of soybean was important for its commercial value. In this study, seed appearance qualities of 235 soybean varieties collected from Chinese Soybean Mini Core Collection including seed shape, seed color, hilum color, glossy seed coat, rate of mottling, seed size (seed length, width and thickness) as well as 100-seed weight were analyzed. The results showed most of the soybeans were with yellow seed coat, brown hilum, glossy seed coat, and in an elliptical shape. Significant difference was detected between seed size and 100-seed weight. Correlation analysis indicated seed width showed positive relation with seed length or thickness, respectively (P
