摘要: 1996~2000年,采用病圃自然感病鉴定法,对我国7省518份大豆新种质资源进行了抗大豆孢囊线虫4号生理小种的鉴定研究,筛选出3个新的抗病品种。这些抗病品种均来自山西,种皮为黑色,每株平均孢囊数在0.2~0.6之间,孢囊指数为0.4~0.6,抗性强而稳定,可供抗病育种利用。

Abstract: During 1996-2000, 518 accessions of new soybean germplasm from 7 provinces of China were evaluated for their resistance to race 4 of soybean cyst nematode(SCN)by natural infection in the field. Three new resistant varieties to race 4 of SCN were obtained. These resistant varieties were all from Shanxi, and all with black seed coat. Their average number of cyst per plant were 0.2-0.6, and cyst index were 0.4-0.6, so that they can be utilized in resistant breeding due to high resistance and stability.

Key words: Soybean, Soybean Cyst Nematode, Evaluation of resistance
