Iowa State University, Southeast Research and Demonstration Farm ISRF07-34 Winter Wheat Variety Test  Ron Skrdla, ag research specialist Lance Gibson, associate professor Department of Agronomy  Materials and Methods Twenty-three varieties were included in the 2007 winter wheat variety at Crawfordsville. Each variety was sown in three different plots to average the effects of soil variability. The varieties were planted October 2, 2006 at a rate of 1½ bushels/acre. The wheat plots were harvested on July 11.  Results Average winter wheat grain yield at Crawfordsville in 2007 was 59 bushels/acre, 27 bushels/acre less than the long-term average yield shown in Table 1. Based on the long-term data, Custer, Hallam, and Overland were the highest yielding varieties among the hard red winter wheat class; Wendy in the hard white winter wheat class; and Kaskaskia in the soft red winter wheat class. Variety 2137 had the highest test weight in 2007 in the hard red winter wheat class, Wendy in the hard white winter wheat class, and INW0412 in the soft red winter wheat class.
