Greenhouse Resistance Screening

Soybean genotypes will be evaluated for resistance to soybean cyst nematode (SCN), Heterodera glycines, by growing the plants in infested soil-sand mix for approximately 30 days, after which the numbers of adult SCN females and cysts on the roots will be assessed. Subsequently, the reaction of individual plants of each soybean genotype to SCN will be classified based on the criteria presented by D.P. Schmitt and G. Shannon in "Differentiating Soybean Responses to Heterodera glycines races", 1992, Crop Science 32(1):275-277.
