Plant Disease Management Reports (online). Report 2:fc003.doi.10.1094/pdmr02. Interpretive Summary: Anthracnose and grain mold are serious fungal diseases of sorghum which can reduce both crop yield and quality, especially when frequent rains occur later in the season. In this study, 30 commercial hybrids were tested for their reactions to these fungal diseases. Six hybrids were highly resistant to anthracnose. All hybrids were heavily damaged by grain molding and grain weathering fungal pathogens. Since none of the hybrids were resistance to either grain mold or grain weathering, additional screening will be conducted on other hybrids to identify resistant sources to these diseases.
Technical Abstract: Thirty commercial hybrids were evaluated for resistance against anthracnose, caused by Colletotrichum sublineolum and grain mold or grain weathering caused by a number of fungal species at the Texas A&M University Agricultural Experiment Station in College Station (Burleson County). Six hybrids were highly resistant to C. sublineolum; whereas all the hybrids tested were highly susceptible to grain mold and grain weathering.
