摘要:
安徽是马铃薯中原二季作区的典型区域,开展马铃薯新品种引进筛选对于带动整个中原二季作区马铃薯品种的更新升级具有重要意义。本试验以费乌瑞它为对照,在安徽开展了中薯20号、中薯7号马铃薯新品种比较分析。结果表明,中薯20号、中薯7号平均鲜薯产量分别为56.42和60.82 t·hm-2, 分别较对照增产34.75%和45.29%;其生育期分别为65 d和67 d,蒸食口感好, 且较抗马铃薯早疫病、晚疫病、卷叶病毒病。适宜在安徽全省种植,可在马铃薯二季作区参考种植。

Abstract:
Anhui Province is a typical double cropping cultivated region of the potato in Central China , in which it is of significance to upgrade the potato varieties through screening of potato varieties. Taken Favorita as control, a comparison test of new potato varieties was carried out in 2012. The results indicated that the average fresh tuber yields of Zhongshu20 and Zhongshu7 were 56.42 and 60.82 t·hm-2, respectively, which were 29.0% and 25.9% more than the control, correspondingly. Their growth periods were 65 d and 67 d. Both varieties have many good traits such as good steamed taste, strong resistance to early blight, late blight and leaf curl virus disease, and are suitable to plant in the whole Anhui Province and other double cropping cultivated region of Central China.
Key words:  potato  new variety  Zhongshu20  Zhongshu7  Anhui
