Resistance in Soybean Cultivars from Maturity Groups V-VIII to Soybean Cyst and Root-knot Nematodes.
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 leve...
متن کاملRefractive index of soybean leaf cell walls.
The refractive index of soybean (Glycine max [L.] Merr.) leaf cell walls was measured by two methods. The refractive index of fully hydrated walls in the living leaf was about 1.415, while that of dried cell walls was about 1.53. The refractive index of the external surface of the living leaf hair was 1.48.
متن کاملTolerance in Maturity Groups V-VIII Soybean Cultivars to Heterodera glycines.
Twenty-six susceptible and resistant soybean, Glycine max, cultivars in Maturity Groups V, VI, VII, and VIII were compared with Coker 156, Wright, and PI97100 for tolerance to Heterodera glycines races 3 and 14. Seed yields were compared in nematicide-treated (EDB, fenamiphos) and untreated plots at two H. glycines-infested locations over 3 years. Coker 488, DP 417, and NK S72-60 had the highes...
متن کاملFighting Asian Soybean Rust
Phakopsora pachyrhizi is a biotrophic fungus provoking SBR disease. SBR poses a major threat to global soybean production. Though several R genes provided soybean immunity to certain P. pachyrhizi races, the pathogen swiftly overcame this resistance. Therefore, fungicides are the only current means to control SBR. However, insensitivity to fungicides is soaring in P. pachyrhizi and, therefore, ...
متن کاملAgronomic performance of two intercropped soybean cultivars
Broader environmental tolerance associated with mixed population of soybean (Glycine max Merr.) cultivars may increase soybean yield potential and play a significant role in yield stability. A field study was carried out to assess whether intercropping of two commonly used cultivars of soybean with different morphological characteristics may increase seed yield in Iran. A split-plot design was ...
