Abstract
Three greenbug [Schizaphis graminum (Rondani)]- resistant sorghum [Sorghum bicolor (L.) Moench] lines, 'IS 809,' 'SA 7536-1,' and 'KS 30,' their F1 hybrids with greenbug-susceptible A lines, three susceptible hybrids, and one susceptible line were planted in yield tests subjected to a natural infestation of greenbugs at Lubbock, Texas in 1971 and 1972. In untreated plots, the mean number of greenbugs per plant was higher and leaf injury from greenbug feeding was greater in susceptible entries than in resistant lines and their hybrids. In greenbug-infested plots, grain yield was significantly reduced only in the early-blooming susceptible line. Hybrids with one resistant parent exhibited enough resistance to control greenbug populations and significantly reduce leaf death from greenbugs feeding on adult plants
