摘　　要：对基于全基因组重测序数据构建的41份野生醋栗番茄核心种质,在150 mmol·L-1 NaCl胁迫下进行芽期耐盐性评价。结果表明:醋栗番茄种质资源的耐盐性存在较大差异,有丰富的遗传多样性,鉴定出耐盐材料13份,盐敏感材料20份。其中N27、N34、N35、N38、N39、N41等6份材料耐盐性较好,相对发芽率达95%以上,显著高于其他醋栗番茄和栽培种Moneymaker、M82。进化树分析结果表明耐盐材料分布在不同类群,推测醋栗番茄耐盐性状受有限的数量性状位点控制。This paper carried out germination stage salt tolerance evaluation at germination stage on 41 currant tomatoes(Solanum pimpinellifolium)core collections constructed based on whole genome resequencing data under 150 mmol·L-1NaCl stress.The results showed that there are great differences existed in these germplasm resources with rich genetic diversity.13 salt tolerant materials and 20 salt sensitive materials were identified.Among them,N27,N34,N35,N38,N39,N41 had better salt tolerance,and the relative germination rate reached over 95%,which was significantly higher than the other currant tomatoes and cultivated species Moneymaker and M82.The results of phylogenetic tree analysis showed that salt tolerant materials were distributed in different groups,suggesting that the salt tolerance of currant tomato was controlled by a limited number of quantitative trait loci.
