1982～1986年,对从东北大豆产区收集的地方大豆品种202份,分别以大豆胞囊线虫的1号和3号生理小种进行田间和盆栽接种鉴定。播种后40～45天,调查每株根上的白色雌虫数,以Hill、丹豆4号和Lee作为感病对照品种,Peking作为抗病对照品种。鉴定结果:有4个小黑豆品种即磨石黑豆、北京黑豆、小粒黑豆和小粒黑,表现抗大豆胞囊线虫的1号和3号生理小种;有4个秣食豆品种表现抗3号小种,但不抗1号小种。 From 1982 to 1986, 202 soybean cultivars collected from the northeastern soybean producing areas were identified by field and pot inoculation with soybean cyst nematode No.1 and No.3. 40-45 days after sowing, the number of white females per plant was investigated. Hill, Dan-dan 4 and Lee were used as the susceptible varieties and Peking as the control varieties. Identification results: There are 4 small black bean varieties that are grindstone black bean, black bean Beijing, small black bean and small black grain, showing resistance to Soybean cyst nematicide No. 1 and No. 3 physiological races; Small species, but not resistant to the first race.
