1986～1990五年内,应用田间自然发病和盆栽接种病土鉴定方法,对河南、河北、安徽、山东、山西、陕西等14个省市保存的8183份大豆种质资源进行了大豆孢囊线虫3号生理小种的抗性鉴定,筛选出免疫品种29份,占参试材料0.35％,抗病品种209份,占参试材料2.55％。鉴定结果表明,抗源材料多为黑种皮大豆,而且不同地区大豆种质资源对大豆抱囊线虫3号生理小种的抗性差异较大。 From 1986 to 1990, 8183 soybean germplasm resources preserved in 14 provinces and cities of Henan, Hebei, Anhui, Shandong, Shanxi and Shaanxi provinces were studied using natural pathogenesis of the field and identification methods of soil inoculated with potted plants. No. Physiological races, screening 29 kinds of immune species, accounting for 0.35% of the tested materials, 209 resistant varieties, accounting for 2.55% of the tested materials. The identification results showed that most of the anti-source materials were black-seed soybean, and the soybean germplasm resources in different regions had significantly different resistance to the soybean racecourse.
