Interpretive Summary: Fungal diseases cause significant yield losses of sorghum in regions where the crop is planted such as Niger. Nineteen sorghum lines used in anthracnose race determination were tested in two locations in Niger to identify resistance to different foliar and panicle diseases. Results showed that all the lines were susceptible to leaf blight and most of them to other diseases such as oval leaf spot, zonate leaf spot, target leaf spot, and long smut. PI570726 was infected by leaf blight but free of the other diseases. This work is significant because it has identified that some of the sorghum anthracnose differentials, especially PI570726 may possess genes for resistance to multiple sorghum diseases and can be utilized as parents in breeding programs.

Technical Abstract: This study was conducted to determine the reactions of 19 sorghum lines, of which 18 had been used for Colletotrichum sublineola pathotype determination to other foliar and panicle diseases in two agroecological zones in Niger. The anthracnose resistant check SC748-5 was infected with leaf blight, oval leaf spot, and zonate leaf spot but free of long smut, rough leaf spot, and target leaf spot. BTx623 and TAM428 which are susceptible to anthracnose were infected with leaf blight, long smut, oval leaf spot and zonate leaf spot. Across locations, all the lines tested were infected with leaf blight, caused by Exserohilum turcicum. PI570726, an accession from Sudan was infected with only leaf blight but free of all the other diseases observed in both locations. This work showed that some of the sorghum anthracnose differentials, especially PI570726 may possess genes for resistance to multiple sorghum diseases and can be utilized as parents in breeding programs in Niger.
