ABSTRACT
The main biotic constraint in sustaining and boosting wheat production is rusts caused by Puccinia species which are historic and devastating pathogens worldwide. Their ability to spread aerially over the continents, production of infectious pustules geometrically in trillions and evolution of new physiologic races makes the management strategies a very challenging task. Identification of pathotypes, anticipatory breeding, evaluation for rusts resistance and deployment of resistant cultivars is a time tested strategy to manage wheat rusts. However, the rust’s pathogen being out smarted and new virulent pathotypes emerged which could overcome the novel rust resistance genes. But the most efficient and economic way for management of wheat rusts is utilization of resistant variety. Identification of resistance genes is essential for gene pyramiding, gene deployment and developing slow rusting wheat cultivars to manage wheat rusts. In this context, molecular markers linked to rust resistance genes assist in marker-assisted selection for validation of rust resistant genes in less time as compared to conventional breeding programme.
