大豆品种对孢囊线虫生理小种抗性反应的研究

THE RESISTANCE OF SOYBEAN LINES TO SOYBEAN CYST NEMATODE RACES

摘要:

国目前已鉴别的生理小种为基础,由6个省11个地点采集带有3个生理小种的土壤。结果鉴定出10个品系抗8号生理小种,其中7个品系兼抗1号生理小种,5个品系兼抗4号生理小种,共有3个品系抗1,3,4号生理小种。试验表明,对大豆孢囊线虫生理小种的抗性鉴定,可用吉林20号作为感病品种以代替Essex。

Abstract:

Based on the physiological races identified in our country, soil samples representing 3 races of SCN were collected to evaluate the resistance of soybean breeding lines. The results indicated that there were 10 lines resistant to race 3, among which 7 were resistant to both race 1 and 3, and 5 were resistant to both race 3 and 4, 3 were resistant to race 1, 3 and 4. The results also showed that Jilin No. 20 could be used as a susceptible check to replace Essex.
