摘要：为了丰富马铃薯分子标记,定位青枯病抗性基因位点,利用具有抗青枯病遗传背景的二倍体马铃薯亲本USW5337.3(C)和772102.37(E)及其123份杂交一代无性系,进行了马铃薯SSR遗传图谱的构建。根据马铃薯全基因组序列设计了864对SSR引物,其中187对在亲本间表现出差异,135对(72.2%)能够在杂交一代中扩增出清晰的条带,最终构建了一张由12个连锁群组成,包含135个SSR标记的马铃薯分子标记遗传图谱。12个连锁群总长度为948.4 c M,标记间平均间距7.03 c M,含有5个标记偏分离区域。不仅为马铃薯饱和分子遗传图谱的构建提供新的SSR标记,对于马铃薯抗青枯病QTL定位、基因克隆和分子标记辅助选择也具有重要的参考意义。
