The Northern Regional Soybean Cyst Nematode (SCN) Test is used to evaluate soybean varieties produced by several public breeding programs in the northern portion of the United States and Canada. In 2018, six public breeding programs participated in the Northern Regional Soybean Cyst Nematode Test (Uniform Test 1). Public breeders can enter varieties into the SCN Uniform Test in exchange for growing locations for the test. Material entered into the SCN Uniform Test is generally in advanced stages of a breeding program. The test is an efficient method for soybean breeders to get multiple location data, in contrast with each individual program growing all of their own locations. It also produces useful information by comparing soybean lines from multiple programs and identifies lines from other states that produce well in Iowa. Results from these tests are used by soybean breeders to select varieties with superior yield and/or disease resistance to continue advancement toward variety release. These results also are used to demonstrate positive characteristics to growers and other interested parties.
