Abstract

Soybean cyst nematode (SCN) is a widespread pest of soybean in Iowa. The nematode is a serious threat to soybean production in the Midwest because it reproduces very quickly, survives in the soil for many years in the absence of a soybean crop, and can cause substantial yield losses. Resistant soybean varieties are a very effective strategy for managing SCN, producing acceptable yields yet suppressing nematode reproduction. The number of maturity group I, II, and III soybean varieties with genetic resistance to SCN has increased dramatically, from a few dozen in the early 1990s to more than 650 currently.
