Research finding on varietal screening of promising lines of sesame resistant to bacterial wilt disease caused by Ralstonia solanacearum Smith
The field testing of 50 sesame lines of three selected numbers 3, 7 and 10 imported from Korea has showed 12 lines with very good agricultural traits. Among them the variety numbered 10 having potential traits such as the moderate to high resistant to bacterial wilt disease, moderate tolerant to stem rot disease, slightly susceptible to green hopper, leave eating bug and also good tolerant to the drough and flooding. Good agricultural practice of this sesame line number 10 can give a high yield ranging from 8.27 quintal to 8.73 quintal/ha. The practice model has indicated a good adaptation in Nghe an ecological zones, reducing the disease incidence by 22 % in comparision to the check plot and subsiquently increased the yield upto 23.52% compared to local variety so called “yiellow sesame”.
