Abstract:
Mustard is an important oilseed crop in India and affected by various biotic factors including Alternaria blight. Alternaria blight not only degrades seed quality but also significantly lowers its oil content. As it is notable that, among various disease management approaches, use of resistant varieties is the best option owing to cost effective and environment friendly approach. However, till now only few resistant sources against this disease has been reported. Therefore, in the present investigation 75 Indian mustard genotypes have been evaluated under field conditions during Rabi 2021-22. Some of the genotypes showed resistance against this disease. These resistance sources will be helpful in developing superior cultivar (s) for managing Alternaria blight where Indian mustard cultivation is prevalent.
