Abstract
This paper presents results of research on the agronomic performance of sorghum [Sorghum bicolor (L.) Moench.] hybrids derived from several germplasm sources that possess resistance to biotype C of the greenbug [Schizaphis graminum (Rondani)]. Significant differences among hybrids with resistance from different sources were evident for grain yield, seeds/head, heads/plant, days to midbloom, and plant height. SA7536-1 seemed superior to KS30, IS809, and PI264453 resistance sources in potential for producing high-yielding hybrids with resistance to biotype C. Greater numbers of seeds/head was the component largely responsible for the yield advantage of the SA7536-1 hybrids.
