An experiment was conducted during 2012-2013 at Regional Agricultural Research Station Jamalpur to findout the resistatnt lines of mustard against Alternaria blight disease. A total of twenty nine lines and varieties of Brassica napus, Brassica campestris and Brassica juncea were used in the experiment. A susceptible check Tori-7 was used between two rows of the test lines. Among the 29 lines only two lines of B. napus, NAP-206 and NAP-0837 and two lines of B. juncia BJ -66 and BJDH-01 were found moderately resistant against the disease.

To develop Alternaria blight disease resistant mustard variety
The experiment was conducted during 2012-2013 at Regional Agricultural Research Station, RARS, Jamalpur to find out the resistant lines/varieties against Alternaria blight disease. A total 0f twenty nine (29) varieties and lines were used in the experiment. Seeds of the lines were sown on 10 November 2012. A susceptible line Tori-7 was used in the experiment as check. Every tested lines were sown in two rows and after two tested lines single row of highly susceptible line Tori-7 was sown. Disease data were recorded following standard disease rating scale 0-5 (Meah, 1994) before 10 days of harvest. Reaction of crop against the disease was graded on following five grade, where HR= No. infection; R= up to 10% disease infection; MR= 10.1 -20% disease infection; MS= 20.1-50% disease infection and; S= above 50% disease infection; (HR=Highly Resistant, R=Resistant, MR=Moderately Resistant, MS=Moderately susceptible, S= Susceptible)
Annual Report
Two lines of U. napus, NAP-206 and NAP-0837 and two lines of B. juncia BJ -66 and BJ 0517 were found moderately resistant against the disease (Table 1). These lines also gave relatively higher yield compared to other tested lines.
