  A study was conducted to investigate the virulence and diversity of blackleg in major brassica growing areas of Ethiopia. The highest blackleg severity was recorded at Holeta on station canola type cultivar with severity range of 3.5% to 25.6%. The rest visited fields were free from black leg disease. Most of the fields were found covered with Brassica carinata which is under species has BB genome which confers resistance to blackleg. A total of 48 fungal isolates were recovered from leaves and steam of Brassica species. 52% of the isolate goes to L. biglobusa followed by L. maculans 31.25%. Morphological characteristics of the isolates were studied on a PDA medium at 25 ± 1°C: Colonies were found circular in shape after 5 days, and were observed in isolates: BLHH-1, BLHH-2, BLHH-3, BHLL-4, LM-1, LM-2, LB-1, and LB-2. ..
