In addition this study suggested that the wheat variety 98-10-30 and Batis had the same resistance when no aphids fed on them. However, the variety 98-10-30 had better resistance for S. graminum, and the variety Batis had better resistance for S. avenae when they were fed by aphids. The variety Amigo had better resistance for S. graminum under all situations.
