Abstract：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-1 NaCl 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．
