摘要：在2012年马铃薯收获期间,对定西师专试验田马铃薯块茎病害进行调查,马铃薯品种为费乌瑞它、早大白、新大坪、陇薯3号、克新1号.结果表明:5个品种中晚疫病发病率均较高,且不同品种间存在明显差异,由高到低依次为费乌瑞它(52.54%)、早大白(47.49%)、新大坪(46.21%)、克新1号(23.42%)、陇薯3号(16.03%).说明本次试验中陇薯3号对晚疫病的抗性最强,其次为克新1号,费乌瑞它的抗性最差,新大坪和早大白对晚疫病的抗性较弱.除晚疫病之外,在不同品种中还出现了粉痂病、黑痣病和疮痂病,具体为:费乌瑞它有疮痂病出现,发病率为10.59%;新大坪有粉痂病,发病率为4.12%;早大白有黑痣病,发病率为8.94%;克新1号有粉痂病、黑痣病和疮痂病,发病率分别为1.27%、3.80%和3.80%;陇薯3号有粉痂病和疮痂病.
Tuber disease of 5 main potato cullivars plan led in Dingxi（Favorila, Zaodahai, Xindaping, Longshu No. 3,Kexin Nn. 1）was investigated during the potato harvest in test field of Dingxi Teachers College in 2012. The results showed that： The disease rate of late blight of all cultivars was higher and that of different varieties had obvious rlifferences, which of Favorita（52.54%）〉 Zaodabai（47.49%）〉 Xindaping（46.21%）〉Kexin No. 1（23.42%）〉Longshu No. 3（16.03%）. I（ showed that the resistance of Longshu No. 3 for late blight is the best, secondly new No. 1,the resistance of Favorita is the worst, the resistance of new Daping and Zaodabai for late blight was low. In addition to late blight, the powdery scab, black scurf and scab also appeared in different varieties, in particular： there is scab disease of Favorita, the incidence rate of it was 10.59%, there is powdery scab of Xindaping, the incidence rate of ii was 4.12%, there is black scurf of Zaodahai, the incidence rate of it was 8.94%; and there is powdery scab, black scurf and scab of Kexin No.l, the incidence rates were 1.27%, 3.80% and 3.80%; lliere is powdery scab, seal） of Longshu No. 3.
