Sources and genetic control of resistance to stagonospora nodorum blotch in wheat. in: research signpost/recent research development in gentics and plant breeding.. Book Chapter. Vol. 1: 449-469 Technical Abstract: Stagonospora nodorum blotch (SNB), caused by the fungus Stagonospora nodorum (Berk.) Castellani and E. G. Germano, is an important foliar and glume disease of bread wheat and durum wheat worldwide. It causes significant losses in grain yield and quality. Host resistance has been considered the most sustainable approach of reducing losses to SNB. Partial SNB resistance under both polygenic and monogenic control has been found in wheat and its relatives. A number of SNB resistance genes and QTLs (quantitative trait loci) have been identified and mapped in the wheat using molecular markers. Molecular markers closely linked with SNB resistance genes or major QTLs could be utilized to enhance breeding for SNB resistance in both durum wheat and common wheat.
