Bipolaris leaf blight (Bipolaris sorokiniana) or spot blotch is currently the number one disease of wheat in Bangladesh. The disease starts at the seedling stage and increases with age. Almost all commercial cultivars are either moderately susceptible or susceptible to this disease. During 1991-92, the yield loss was estimated to 29.0 in the variety Kanchan. While Kanchan is slightly more tolerant to the disease than earlier released varieties, there has been little progress made in the further development of resistance due to a lack of resistance sources. Recently, new sources have been identified and will be used in the breeding program
