"Ergot or sugary disease of sorghum has become an important constraint in North and South American countries that\r\nrely on F1 hybrid seeds for high productivity. The objective of this research was to determine the vulnerability of\r\nvarious germplasm sources and publicly bred sorghum lines to sugary disease (Claviceps africana) in the United\r\nStates. Flower characteristics associated with sugary disease resistance were also studied. A-/B-line pairs, R-lines,\r\nputative sources of resistance and their hybrid combinations with an A3 cytoplasmic male-sterile source were\r\nevaluated using a disease incidence, severity, and dual-ranking system. Trials were planted in a randomized complete\r\nblock design with three replications and repeated in at least two planting dates. Planting dates and pedigrees had\r\nsignificant effects on overall ranking for resistance. A-lines were most susceptible to sugary disease. R-lines were\r\nmore susceptible than B-lines with respect to incidence and severity of the disease. Newer releases of A- and B-lines\r\nwere more susceptible to sugary disease than older releases. Sugary disease reaction of A-lines was a good indicator of\r\ndisease reaction of B-lines. Tx2737, a popular R-line, was highly susceptible to sugary disease in spite of being a good\r\npollen shedder because the stigma emerged from glumes 2±3 days before anthesis. The combination of flower\r\ncharacteristics associated with resistance were least exposure time of stigma to inoculum before pollination, rapid\r\nstigma drying after pollination, and small stigma. An Ethiopian male-fertile germplasm accession, IS 8525, had good\r\nlevels of resistance. Its A3 male-sterile hybrid had the highest level of resistance in the male-sterile background. IS\r\n8525 should be exploited in host-plant resistance strategies."^^ . "2001" . . "50" . "6" . . "Blackwell Publishing"^^ . . . "Plant Pathology"^^ . . .
