摘要: 为了分析从国内外搜集的无花果品种的遗传多样性,利用SSR荧光标记毛细管电泳检测法构建了30份无花果品种的指纹鉴定平台。以15对SSR荧光引物对30份无花果品种资源进行分析,结果共检测到79个等位变异。15个位点的PIC值在0.332 8~0.875 7,平均为0.530 3;各位点的 Shannon 信息指数(I) 为0.604 9~2.127 3,平均为 1.136 0。30份品种资源的遗传距离在0.025 4~1.123 4。其中引物FCUP038-6的杂合度、PIC 值分别高达0.846 8、0.861 1,可考虑作为以后区试杂交种纯度鉴定的核心标记。30份无花果品种资源表现出比较丰富的遗传多样性,聚类分析结果显示,30份资源被分为两组,来源不同的品种被分散聚类。同时,无花果品种的亲缘关系与其来源和表型特征并不存在明显的相关性。

Abstract: In order to analyze the genetic diversity of the fig species collected from home and abroad, the capillary electrophoresis detection with fluorescent SSR markers method was used to establish the fingerprint identification platform of 30 fig varieties. Analysis of 30 fig varieties was performed by using 15 pairs of SSR primers. The results showed that a total of 79 alleles were detected, the PIC value of 15 loci was between 0.332 8 and 0.875 7 with an average of 0.530 3 and the Shannon information index (I) of each point was between 0.604 9 to 2.127 3 with an average of 1.136 0. The genetic distance between the 30 varieties was 0.025 4-1.123 4. Among them, the heterozygosity and PIC value of primer FCUP038-6 were up to 0.846 8 and 0.861 1, respectively, which could be considered as the core marker of the purity of the hybrid test. Thirty fig varieties were rich in genetic diversity and were divided into two groups with different origins. There was no significant correlation between the genetic relationships and the origins of the varieties, as well as the phenotype feature.
