Evaluation of Soybean Cultivars for Production in Meloidogyne incognita-infested Soil.
نویسندگان
چکیده
Significant (P < 0.05) differences among galling and yields of 41 soybean cultivars and breeding lines were found when they were produced at a site infested with Meloidogyne incognita during 3 years of investigation. Over a period of 6 years of testing, 13 cultivars were identified as having a suitably low susceptibility to warrant their production in M. incognita infested soil.

Galling and Yields of Soybean Cultivars Grown in Meloidogyne arenana-Infested Soil.
Field trials with 39 soybean cultivars and five breeding lines from public and private sources were conducted from 1982 through 1985 at sites infested with Meloidogyne arenaria. Nematode population densities and root-knot galling were measured for each soybean entry. All were efficient hosts for the nematode, and average juvenile numbers in the soil increased 5-50 x from planting to harvest. Di...
متن کاملHost Suitability of Soybean Cultivars for Meloidogyne incognita and M. arenaria.
The suitability of five maturity group (MG) III and five MG IV soybean, Glycine max, cultivars as hosts for Meloidogyne incognita and M. arenaria was evaluated in a greenhouse. 'Forrest', a MG V cultivar, was used as the standard of comparison for M. incognita resistance. With M. incognita, root-gall and egg-mass indices and reproductive factors for 'Asgrow 3307', 'FFR 398', and 'Pioneer 9442' ...
متن کاملInfluence of Maize Rotations on the Yield of Soybean Grown in Meloidogyne incognita Infested Soil.
A replicated field study was conducted from 1972 to 1980 involving soybeans grown in 2-, 3-, and 4-year rotations with maize in soil infested with Meloidogyne incognita. Monocultured soybeans were maintained as controls. Cropping regimes involved root-knot nematode susceptible and resistant soybean cultivars and soybeans treated and not treated with nematicides. Yields of susceptible cultivars ...
متن کاملEffects of cultivars, subsoiling, and fumigation on soybean yields and Meloidogyne incognita populations.
Application of 1,2-dibromo-3-chloropropane (DBCP) and subsoiling under the row in Tifton sandy loam heavily infested with Meloidogyne incognita increased yields of four soybean cultivars. These cultivars have levels of resistance to M. incognita as follows: 'Hutton', high; 'Essex', intermediate; and 'Davis' and 'Ransom', low. After growing these four cultivars, sub-soiling, and applying DBCP fo...
متن کاملEvaluation of Soybean Cultivars for Production in Meloidogyne arenaria Race 2-Infested Soil.
Field trials with 56 soybean cultivars and breeding lines from public and private sources were conducted from 1986 through 1988 at a site infested with Meloidogyne arenaria race 2. Differences (P < 0.05) among yields were found each year and yields were negatively correlated (P < 0.01) with root-knot nematode galling. All entries were galled and the highest-yielding entries, 'Kirby' and 'Coker ...
