| Abstract: | 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. |
