Abstract

86 words

Sorghum cultivars grown in East and Central Africa are susceptiple to various foliar diseases, of which turcicum leaf blight, caused by Exerohlium turcicum, causes severe damage. The best way to control foliar diseases is by breeding resistant sorghum genotypes This can be best done with the help of marker assisted breeding technology and also by deploying multiple genes that confer either qualitative or quantitative resistance. In this research project, we intend to identify quantitative trait loci and molecular markers tightly linked with resistance to Exerohilum turcicum.
