Abstract

Alternaria blight incited by Altenaria brassicae is one of the most important disease of rapeseed-mustard crop. Forty two cultivars /genotypes of rapeseed-mustard group (Brassica juncea, Brassica campestris, Brassica carinata, Brassica napus, Eruca sativa and B. rapa) were carried out during the rabi 2011-12 under artificial conditions. UDN 11-05(13.0% leaves, 15%pod) genotype was found resistant against alternaria blight. The Present study indicates that B. napus, B. juncea and B. carinata were found better source of resistance in comparison to Brassica campestris. UDN-11-05(13.0% leaves, 15.0% pod) genotype was found resistant against the disease. Whereas UDN-11-29 (16.9% leaves,14.3% pod), UDN-11-36 (20.5% leaves, 18.0 % pod) and UDN-11-10 (20.8% leaves, 20.2% pod) were rated as moderately resistant to the disease.
