Summary The greenbug, Schizaphis graminum (Rondani), is a serious pest of wheat, Triticum aestivum L., and other small grains. Cultivar resistance would be an efficient means of control. Unfortunately, a paucity of greenbug resistance in wheat germplasm and occurrence of new virulent biotypes of the greenbug have made development of resistant cultivars difficult. Therefore, resistance genes are sought in species related to and crossable with wheat. Our objective was to evaluate, in greenhouse seedling tests, 11 rye (Secale cereale L.) accessions for their reaction to greenbug biotypes B, C, E, and F. Two ryes, CI 187 and PI 240675, segregated for resistance to all four biotypes. It may be possible to transfer this resistance to wheat. These resistance sources may also be of importance in rye and triticale (X Triticosecale Wittmack) breeding.
