馬鈴薯晚疫病是甘肃省高山多雨地区較普遍而又严重的病害。其发病程度,虽因各年份气候条件不同而有差异,但因一般年份雨量多,气候凉,适于病害的发生、发展和蔓延,常常造成重大的損失。为了根本地解决这一問題,从1955年开始我們在岷县地区进行了抗病育种工作。当年在武都县所进行的品种比較試验中,初步选出抗病丰产的甘岷一号,56—57年又在 Late blight of potato is a more common and serious disease in the mountainous and rainy area of ​​Gansu Province. Although the incidence varies according to the climatic conditions in different years, it is often caused by heavy rainfalls and cold weather in general years, which is suitable for the occurrence, development and spread of diseases, and often causes heavy losses. In order to solve this problem fundamentally, we started the disease-resistant breeding in Minxian County from 1955 onwards.
