Research

Many greenhouse screening methods have been tested to evaluate soybean genotypes for reaction to sudden death syndrome (SDS). These methods generally have proven disappointing in that results are inconsistent among methods or don’t correlate with field reaction. In this study, SDS foliar symptom severity among 24 soybean genotypes was compared using three greenhouse inoculation methods. A water bath method was superior to the other methods in consistency of SDS symptoms among genotypes among trials and in agreement with SDS field reaction.
