摘要
对梨属 4 0个品种及类型进行了RAPD扩增 ,根据相似系数进行UPGMA法聚类 ,将起源于欧洲的西洋梨与起源于中国的 3个种明显区分开 ,起源于中国的 3个种虽未完全各自聚类 ,但各材料间都有不同的遗传距离 。
Random amplified polymorphic DNA (RAPD) analysis was done on 40 Pyrus cultivars. Based on the similar coefficient, the clustering analysis was done. The results showed that Pyrus communis L. originated in Europe could be distinctly distinguished from the other three species originated in China by RAPD technique. Three Chinese species were not clustered into different groups respectively, but there were different distance between any two accessions. It showed that RAPD technique could be used in the classification and identification of Pyrus of species.
