Evaluation of all disease and insect nursery sorghum germ plasm for susceptibility to covered kernel smut
Phytopathology 86 (11 suppl.), S63-S63
Abstract: Covered kernel smut (Sporisorium sorghi) causes significant yield losses in many areas of the world where seed treatments are either unavailable or too expensive. Since 1984 (except 1985) grain sorghum accessions obtained from the All Disease and Insect Nursery, [courtesy D. T. Rosenow, Texas AandM, Lubbock, TX] were screened for susceptibility to covered kernel smut. Seeds were infested with S. sorghi teliospores (0.5% w/w) prior to planting. Plants were evaluated in October for disease. Ten entries were scored in all years (B35-6, BTX378, BTX623, QL3, SC326-6, SC414-12, Tam 428, TX2767, TX430, and TX7078). Two entries (B-35 and SC414-12) were immune to the disease. For the other eight entries, susceptibility appeared to be environmentally dependent and varied from year to year. However, the means of these entries over the 11-yr period indicates that they are susceptible to the pathogen.
