摘　　要：为摸清贵州省低海拔地区主栽马铃薯品种对晚疫病的抗性情况,于2010-2011年在黄平县低海拔区域进行了贵州省主栽马铃薯品种晚疫病的田间抗性试验。结果表明:2010年19个参试品种抗性存在明显差异,表现较好的中抗以上的品种有5个(米拉、威玉3号、宣薯3号、W04-12、B0402-2),占参试品种的26.32%。2011年受春夏连旱影响,马铃薯晚疫病发病轻,11个参试品种均表现为抗病,品种间抗病性差异不显著,有待进一步研究。Field resistance on late blight of major cultivation potato varieties were studied in low altitude areas in Huangping,Guizhou from 2010 to 2011.The results showed that the difference on resistance to late blight among 19 tested potato varieties was significant,among them,5 varieties （Mila,Weiyu 3,Xuanshu 3,W04-12,and B0402-2） were performed mid-high resistance,which counted 26.32％.11 varieties out of the 19 were showed resistance to late bright in 2011,the late bright was lighter since it was effected by spring-summer drought,and there was no significant difference among the 11 varieties,it needed to be further studied.
