桂西南早熟荔枝实生资源遗传多样性的ISSR分析
Genetic diversity of early-maturing seedling litchi resources in southwest Guangxi by ISSR
摘要
Abstract
The genetic diversities of 83 early-maturing litchi(variety) plants were examined by using ISSR markers in this study. Ten primers gave reproducible, polymorphic DNA amplification patterns with a total of 128 amplified bands. The percentage of polymorphic band was 83. 59%,which showed that the early-maturing seedling litchi resources in southwest Guangxi had abundant genetic diversity. The genetic similarity ranged from 0. 64 to 0. 95 based on DICE. A dendrogram was constructed by UPGMA method,and the early-maturing litchi(variety)plants were distinguished from cultivar litchi at a similarity coefficient criterion of 0. 75. No significant correlation between the dendrogram and geographical distance was revealed among the resources.关键词
