大豆品种之间对大豆孢囊线虫Heterodera glycines存在明显的抗性差异,在感病品种的根系上形成大量的线虫胞囊,而在抗病品种的根系上不形成或形成很少的孢囊.其它国家学者也作过许多观察和试验,据此,我们通过分别接种大豆孢囊线虫1号和3号生理小种,筛选出几个抗性好的小黑豆和秣食豆品 Soybean cultivars showed significant resistance differences to Heterodera glycines. Large numbers of nematode cysts were formed on the root of susceptible cultivars, but few cysts were formed or formed on the roots of resistant cultivars. Other countries have made many observations and experiments, according to which, we were inoculated with Soybean cyst nematode No. 1 and No. 3 physiological races, we screened several resistant black beans and mung bean products
