青枯病是马铃薯生产上重要病害之一，在我省危害相当严重。建立青枯病专用病圃可有效的评价筛选抗病资源材料，供育种和生产利用。通过两年病圃的初步评价，从我所选育、收集的部分资源材料和常规品种（系）中筛选出为中抗的材料９份。两年平均结果病指相对值大于７０％，属于高抗（Ｒ）的株系为０，病指相对值于４０％～７０％之间为中抗（ＭＲ）的占参试株系的１９．２９％，病指相对值于２０％～４０％属中感（ＭＳ）的占参试株系的３５．０９％，病指相对值小于２０％属感（Ｓ）的占参试株系的４５．６１％。从病圃发病株率和病指可以看出，成都地区马铃薯生长季节青枯病发病情况春季主要集中在５月份，秋季主要集中在１０份，春季病情严重，秋季发病轻。
Bacterial wilt is one of the most important diseases in potato production, which is very serious in our province. The establishment of a dedicated bacterial wilt nursery can effectively evaluate the screening of disease-resistant resources for breeding and production. Based on the preliminary evaluation of nursery for two years, 9 materials were screened from some of the resource materials and conventional varieties (lines) selected and collected by me. Two-year average results indicated that the relative value of disease means more than 70%, the strain with high resistance (R) is 0, and the relative value of disease means between 40% and 70% , Accounting for 35.09% of the tested lines with relative value of 20% -40% of the disease index (MS), less than 20% Of 45.61%. It can be seen from the incidence rate and disease index of nursery plants that the incidence of bacterial wilt in potato growing season in Chengdu is mainly concentrated in May in autumn, mainly in autumn in 10, and the disease is serious in spring and light in autumn.
