@@@@为筛选出产量高、抗晚疫病性强、适宜贵州山区大面积推广的优良品系，在适宜马铃薯种植和晚疫病流行的威宁县对21个马铃薯品系(种)作田间抗病性鉴定和产量比较试验。结果表明：11个品系表现为高产、抗晚疫病，产量与对照‘威芋3号’呈极显著差异，比对照增产84.3%～201.6%。经相关分析，不同马铃薯品系的晚疫病感病等级和产量呈极显著负相关，相关系数为-0.745。

A comparison experiment of 21 new potato strains was carried out in Weining county, where is suitable for potato planting and late blight. Our aim is to choose new potato variety with high yield and late blight-resistant in Guizhou province. The results showed that eleven potato strains get high yield increase by 84.3%~201.6%, and high resist to late blight. There are significant difference between yield of each eleven potato strain and that of control (Weiyu number 3). The result of correlation analysis showed that late blight severity levels and yield of different strains is highly significant negative correlation with the correlation index of-0.745.
