摘　　要：鄂薯和华薯系列马铃薯品种是由湖北恩施中国南方马铃薯研究中心和华中农业大学马铃薯团队选育而成的品种。鄂薯系列马铃薯品种大多为中晚熟品种,适合西南山区种植;华薯系列马铃薯品种多为早熟品种,适于华中低山丘陵和平原地区种植。研究对2个系列品种部分晚疫病抗病基因进行了分子标记检测,同时对几个水平抗性相关基因SNP位点进行了检测。研究表明,鄂薯、华恩和华薯系列部分马铃薯品种含有R3a、R3b基因,鄂薯和华恩系列含有R8基因。总体上R8标记与抗性存在正向关联。部分马铃薯品种中可以检测到一些已报道与田间抗性有关的SNP位点,但品种晚疫病抗性表现与SNP位点分布无明显关联。Eshu and Huashu series potato varieties are bred and developed by China Southern Potato Research Center and Potato Group of Huazhong Agricultural University in Hubei Province.Eshu series potato varieties are mostly mid to late maturing varieties,suitable for planting in southwest mountainous areas.Huashu series potato varieties are early maturing varieties,suitable for planting in low mountains and plains of central China.In this research,molecular markers were used to detect some late blight resistance genes and single nucleotide polymorphism(SNPs)of several horizontal resistance related genes.The results showed that Eshu,Huaen and Huashu series potato varieties contained late blight resistance gene R3a and R3b.Eshu and Huaen series potato varieties contained R8.Generally,the presence of R8 maker has positive relationship with late blight resistance.Some known late blight resistance related SNPs were detected in several varieties,but there is no close relationship between SNPs and blight resistance.
