【摘要】 在盆栽条件下，强迫大豆孢囊线虫１号生理小种的群体在抗病品种上繁殖１０－１２代，用一套鉴定大豆孢囊线虫生理小种的鉴别品种，重新鉴定经抗病基因选择后的大豆孢囊线虫的生理小种类型，鉴定结果表明：原来为１号生理小种的线虫群体，经在抗病品种Ｐｅｋｉｎｇ和Ｆｒａｎｋｌｉｎ上连续选择１２代之后，变为４号小种；经在小粒黑豆上选择之后变为５号小种；经在铁丰１８上选择之后变为６号小种；经在Ｆａｙｅｔｅ和小粒黑上选择之后变为９号小种。更多还原

【Abstract】 The populations of race 1 of soybean cyst nematode (SCN), Heterodera glycines, were challenged to reproduce on resistant soybeans for 10-12 generations during 1986-1996, and then all the populations selected were retested their race status on the differential hosts of soybean cyst nematode. The results showed that the populations of the race 1 selected on resistant soybeans Peking and Franklin acted as race 4; on Xiaoli Black, as race 5; on Tiefeng 18, as race 6; on Fayette and Xiaoli Black, as race 9.更多还原
