Comparison of inoculation techniques for screening grain sorghum to kernel smut Sporisorium sorghi
Phytopathology 86 (11 suppl.), S59-S59
Abstract: The efficacy of different application methods was evaluated for screening sorghum (Sorghum bicolor (L.) Moench) to covered kernel smut caused by Sporisorium sorghi. Teliospores were applied to seed and were vacuum infiltrated prior to planting. Teliospores were also injected into the growing point of sorghum plants. Significant differences (p < 0.05) in grain smut incidence were detected among the sorghum genotypes and inoculation techniques. Date of planting was also significant as late planting resulted in an increase of smutted panicles. There were significant genotype x inoculation interactions. Two cultivars (SC414 and B35-6) were immune to covered kernel smut in both field and greenhouse tests.
