Bacterial wilt (Ralstonia solanacearum) is the most destructive disease in solanaceous crops that is threatened to brinjal production with other crops. The 12 isolates of R. solanacearum on seeds of brinjal with different seed sources in Bangladesh were studied to determine the genetic variability on Random amplified polymorphic DNA (RAPD) with OPA18 marker. The highest bacterial infection (93.00%) was obtained with seeds of isolate Al-Amin Beez Vander while the lowest (14.00%) was in Metal seed company Ltd. In molecular level, the 17 bands (100%) of the 17 distinct bands were revealed as polymorphic. Dendrogram based on Nei’s (1972) genetic distance of unweighted pair group method with arithmetic means segregated the isolates of R. solanacearum in two main clusters, as cluster 1 ... view more»
