| 摘 要： | 粉痂病严重影响马铃薯的产量和品质,是我国马铃薯产业健康发展的重要制约因素之一。为进一步探明马铃薯粉痂病在云南省的发生、分布及危害情况,本研究于2018年-2019年,在云南省内马铃薯不同生态种植区,开展了马铃薯粉痂病的发生与危害情况调查。调查范围涉及19个县(区)、涵盖了19个当地马铃薯主栽品种(系)。调查结果显示:粉痂病在云南发生普遍,发病率在0%~51.72%,平均发病率和病情指数分别为15.01%和5.32。其中春作区马铃薯粉痂病的发生较为普遍,平均发病率为25.08%,病情指数为8.24。冬作区马铃薯粉痂病在部分产区有发生,平均发病率为4.93%,病情指数为2.39。与2004年-2008年云南省粉痂病调查数据相比,粉痂病发病率下降,病害有所减轻。

| Abstract: | Powdery scab seriously affects the yield and quality of potato,which is an important factor restricting the healthy development of China’s potato industry.To further ascertain the occurrence of potato powdery scab and distribution in Yunnan province,the occurrence and damage of potato powdery scab were investigated in different ecological planting areas of potatoes in Yunnan province in 2018-2019.The survey covered 19 counties(districts)and 19 local potato cultivars(lines).The results showed that powdery scab was common in Yunnan,with an incidence between 0%-51.72% and an average incidence and disease index of 15.01% and 5.32,respectively.Among them,the occurrence of potato powdery scab in spring crop area was relatively common,with an average incidence of 25.08% and the disease index of 8.24.Winter crop area powdery scab of potato occurred in some areas,with the average incidence of 4.93% and the disease index of 2.39.Compared with 2004-2008 survey data of powdery scab disease in Yunnan province,the incidence of powdery scab disease has decreased and the disease become lighter. |
