摘　　要：为了筛选适合贵州冬播区种植的高产及抗晚疫病马铃薯品种,采用田间试验方法,对贵州生产上主推的9个马铃薯品种进行了筛选。结果表明:贵州主推的9个马铃薯品种均不抗晚疫病,其中,云薯301抗性稍好,为中感(MS);会-2、威芋3号和云薯301产量较高,分别为2 230.0kg/667m2、2 206.4kg/667m2和2 174.5kg/667m2。云薯301适合在贵州马铃薯冬播区种植,对晚疫病防治水平较高的地区也可以选用会-2和威芋3号种植。Nine main eultivars were screened in a field experiment to select the appropriate potato cultivars with high yield and late blight resistance in winter-sowing areas in Guizhou. The results showed that all the nine cultivars did not have resistance to late blight. Yunshu 301 had moderate susceptibility to late blight. The yields of Hui-2, Weiyu 3 and Yunshu 301 were high, 2 230.0 kg/667m2, 2 206.4 kg/ 667m2 and 2 174.5 kg/667m2 respectively. Yunshu 301 was suitable to be planted in winter-sowing areas in Guizhou, Hui-2 and Weiyu 3 could be planted in areas with high prevention and control level of late blight.
