The tactic of choice for managing soybean cyst nematode (SCN) in infested fields is the use of resistant cultivars. Because expression of SCN resistance is dependent on the occurrence and frequencies of genes for virulence in SCN populations, labeling of SCN-resistant cultivars can be difficult and, occasionally, highly misleading, leading to unanticipated yield losses. The authors’ objective was to offer a set of standards for assessing and labeling SCN-resistant cultivars that would allow farmers to make direct comparisons of cultivars.
