Abstract:

Alternaria blight of mustard caused by Alternaria brassicae (Berk.) Sacc., is one of the major diseases of Indian mustard [Brassica juncea (L.) Czern & Coss.]. Among the eight tested media for growth of A. brassicae, Mustard leaf extract was recorded as most suitable for growth and sporulation in all the 20 isolates of A. brassicae. This was followed by Potato dextrose agar and Cabbage leaf extract medium. The maximum mycelial growth of 88.3 mm was recorded in Mustard leaf extract after 12 days of inoculation. The isolates were grouped into 4 categories based on growth and sporulation. In total 11 and 9 isolates were recorded as abundant growing on mustard leaf extract and potato dextrose agar medium respectively. However, all the 20 isolates were recorded as poor or slow growing on all the media except PDA and mustard leaf extract media. The minimum average mycelia growth of 32.28 mm was recorded in carrot agar medium after 12 days of inoculation which showed least supporting medium for growth of A. brassicae among the eight tested media.
