利用AFLP分子标记技术对毛竹等28个刚竹属的竹种进行了遗传多样性分析,共筛选出14对多态性好、清晰度较高的引物组合,获得785个位点,其中多态性位点654个,占总位点的83.31%。利用POPGENE1.32软件对AFLP数据进行分析,结果表明,观测等位基因数为1.8303,有效等位基因数为1.4211,Nei’s基因多样性指数为0.2551,Shannon信息指数为0.3913,并根据遗传距离进行UPGMA聚类分析。 AFLP molecular markers were used to analyze the genetic diversity of 28 bamboo species from Phyllostachys such as Phyllostachys praecox. A total of 14 pairs of primer combinations with good polymorphism and high resolution were screened, and 785 loci were obtained, of which polymorphism There were 654 sex loci, accounting for 83.31% of the total loci. The analysis of AFLP data using POPGENE1.32 software showed that the number of observed alleles was 1.8303, the number of effective alleles was 1.4211, the Nei’s gene diversity index was 0.2551 and Shannon’s information index was 0.3913, and the UPGMA Cluster analysis.
