基于SSR标记的江苏省花生地方品种遗传多样性分析
Genetic diversity of peanut landraces in Jiangsu Province based on SSR markers
摘要
Abstract
In order to assess the genetic diversity of peanut in Jiangsu Province,133 accessions of peanut landraces were evaluated by 25 SSR markers.93 alleles were amplified,and the average number of alleles per locus was 3.72.The polymorphic information content (PIC) of each primer varied from 0.066 to 0.749 with an average of 0.374.Shannon's information index of each primer varied from 0.161 to 1.385 with an average of 0.671.The similarity coefficients of 133 peanut landraces varied from 0.416 to 1.000 with an average of 0.830.The order of average similarity coefficient of 4 types of peanut was Arachis hypogaea L.var.hypogaea (0.899) ＞ var.hirsute (0.776) ＞ var.vulgaris (0.710) ＞ var.fastigiata (0.700).Cluster analysis with UPGMA showed that the landraces could be divided into three groups at 0.600 of genetic similarities coefficient.The results showed that there were rich genetic diversity of peanut landraces in Jiangsu Province,and the genetic diversity was significantly lower among the var.hypogaea than those of the other three types.The result of cluster analysis had important significance for efficiently using of these peanut landraces.关键词
