Interpretive Summary:

Technical Abstract: The soybean cyst nematode (Heterodera glycines Ichinohe) (SCN) is a widely-distributed, economically important pest in the soybean production regions of the United States. To assess the impact of planting SCN-resistant and -susceptible soybean cultivars in SCN-infested or -non-infested fields on soybean yield, research sites were established in 1994 and 1995 in 63 fields that were either SCN-infested or -non-infested in 10 states of the north central USA. Eight SCN-resistant and eight SCN-susceptible public soybean cultivars representing MG's I to IV were planted at each location. Soil samples were taken at planting to determine initial nematode population, SCN race, and soil classification. Soybean yields ranged from 658 to 3840 kg/ha across the sites. Soybean cyst nematode-resistant cultivars yielded better at SCN-infested sites but lost this superiority to susceptible soybean cultivars at non-infested sites. Highly significant interactions were measured among initial nematode population, cultivar, and location. Due to the significance of location, no region-wide predictive equations could be developed for yield loss based on initial nematode populations in the soil. Yield loss due to SCN was confounded by other stress factors which included temperature and moisture extremes.
