Abstract Chromosome segment substitution lines (CSSLs) are valuable genetic resources for quantitative trait loci (QTL) mapping of complex agronomic traits especially suitable minor effect QTL. Here, 162 BC 3 F 7 –BC CSSLs derived from crossing two susceptible parent lines, soybean [ Glycine max (L.) Merr.] ‘Suinong14’ (recurrent parent) × wild ( G. soja Siebold & Zucc.) ZYD00006, were used...

Soybean [Glycine max (L.) Merr.] is an important crop rich in vegetable protein and oil, and is a staple food for human and animals worldwide. However, soybean plants have been challenged by soybean cyst nematode (SCN, Heterodera glycines), one of the most damaging pests found in soybean fields. Applying SCN-resistant cultivars is the most efficient and environmentally friendly strategy to mana...

Soybean breeding lines and reported sources of nematode resistance were evaluated in repeated greenhouse tests for resistance to North Carolina populations of the soybean cyst nematode Heterodera glycines, reniform nematode Rotylenchulus reniformis, and the root-knot nematode species Meloidogyne incognita, M. arenaria, and M. arenaria. Lines from the soybean breeding program in Missouri that ha...

Reproduction of the soybean cyst nematode (SCN), Heterodera glycines Ichinohe, on soybean, Glycine max (L.) Merr., has been compared in conventional till and no-till field plots. Rate of SCN population density increase during the growing season was lower in no-till than in conventional till plots (3,5), or the number of SCN at harvest was lower in no-till than in conventional till plots (6). In...

Soybean cyst nematode (SCN) (Heterodera glycines Ichinohe) is one of the most damaging pests of soybean (Glycine max (L.) Merr.). Host plant resistance has been the most effective control method. Because of the spread of multiple SCN races in Hokkaido, the Tokachi Agricultural Experiment Station has bred soybeans for SCN resistance since 1953 by using 2 main resistance resources PI84751 (resist...

The soybean cyst nematode (SCN) Heterodera glycines is the most devastating pest of soybean in the U.S.A. The resistance response elicited by SCN in soybean is complex, and genes involved in the response to a large extent are unknown and not well characterized. We constructed cDNA libraries made from mRNA extracted from roots of the resistant soybean Glycine max L. Merr. 'Peking' at 12 h, 2 to ...

Use of resistant cultivars is one of the major tactics for combating soybean cyst nematode, Heterodera glycines Ichinohe, which is the most destructive pathogen affecting soybean seed production. However, developing new H. glycines-resistant soybean cultivars is a very labor-intensive process, partially due to the lack of a quick method for counting the H. glycines females that develop on soybe...
