One hundred thirty-nine cultivars of soybean (Glycine max) in Maturity Groups V, VI, VII, and VIII were evaluated in a greenhouse for resistance to Heterodera glycines races 3 and 14 and Meloidogyne incognita, M. arenaria, and M. javanica. Of the cultivars tested, 37% had resistance to H. glycines race 3 alone, 12% had resistance to both races 3 and 14, and 69% exhibited a moderate or high level of resistance to one or more of the Meloidogyne spp. However, 24% were susceptible to each race of H. glycines and to all Meloidogyne spp. Whereas 40% of the cultivars were moderately resistant to M. javanica, only 23% were moderately resistant to M. incognita and 24% to M. arenaria. Although 28% of the cultivars had a high level of resistance to M. incognita, only 6 and 3% had this level of resistance to M. javanica and M. arenaria, respectively. Seventeen percent of the cultivars possessed a moderate or high level of resistance to all three Meloidogyne spp., and 37 % had resistance to H. glycines race 3 and M. incognita. With the exception of resistance to H. glycines race 14, resistance in soybean to these nematodes was fairly uniformly distributed across maturity groups.
在温室中对139个V、VI、VII和VIII成熟组的大豆（Glycine max）品种进行了评价，以检测其对大豆孢囊线虫3号和14号生理小种以及南方根结线虫、花生根结线虫和爪哇根结线虫的抗性。在所测试的品种中，37%仅对大豆孢囊线虫3号生理小种具有抗性，12%对3号和14号生理小种均有抗性，69%对一种或多种根结线虫表现出中度或高度抗性。然而，24%的品种对大豆孢囊线虫的每个生理小种以及所有根结线虫均敏感。40%的品种对爪哇根结线虫具有中度抗性，而对南方根结线虫和花生根结线虫具有中度抗性的品种分别仅占23%和24%。虽然28%的品种对南方根结线虫具有高水平抗性，但对爪哇根结线虫和花生根结线虫具有这种抗性水平的品种分别仅占6%和3%。17%的品种对所有三种根结线虫均具有中度或高度抗性，37%的品种对大豆孢囊线虫3号生理小种和南方根结线虫具有抗性。除了对大豆孢囊线虫14号生理小种的抗性外，大豆对这些线虫的抗性在各成熟组中分布较为均匀。
