Genetic Diversity of Local Mulberry Varieties from Different Ecotypes Revealed by ISSRs in China

摘要：

12 SSR primers generated a total of 83 amplification products, of which 50 were polymorphic, revealing 60.24％ polymorphism among 66 mulberry local varieties, the mean PIC value was 0.1469. The mean genetic similarity coefficient was 0.8456, genetic similarity coefficient among 8 mulberry populations ranged from 0.8441 to 0.9640, indicating that genetic diversity of different populations existed variation. A dendrogram of all 66 local varieties of mulberry based on the genetic similarity using ISSR markers was generated by UPGMA cluster method. In the dendrogram, most varieties from the same ecotype clustered together.
