本研究基于2 份在果实与抗性上存在显著差异的茄子的全基因重测序数据,鉴定出151327 个InDel 位点,随机选择并设计了180 个InDel 标记,利用重测序材料及其杂交一代进行有效性鉴定,结果显示:180 个InDel 标记均可获得PCR扩增产物,其中62 个标记具有多态性,多态率为34.7%。基于InDel 标记聚类分析结果揭示出24 份茄子自交系和143 份茄子品种的遗传多样性。基于2 对InDel 标记的茄子品种纯度鉴定结果与田间鉴定结果相吻合。
In this study, 151327 of InDels were in silico identified by taking advantage of whole genome re-sequencing of two eggplant (Solanum melongena) lines. The primers targeting 180 InDel loci were developed, which were subjected in tests of two re-sequencing eggplant lines and derived hybrid line. Out of that, sixty-two (34.7%) of total primers were polymorphic between both varieties. In addition, the genetic diversity and specificity of 24 eggplant lines and 143 varieties were investigated by use of these markers. The results from purity test of variety from two InDel markers matched well with those from field experiments.
