Abstract
Thirty-eight single spore isolates of Magnaporthe grisea were isolated from the collection of blast infected rice leaves of a hotspot area in West Bengal. The polymorphic DNA banding pattern of the blast isolates for MGR 586 primer were analyzed to study the genetic variation and for the grouping of the isolates. Four clear groups were observed at 85 percent similarity level. This study reveals that MGR 586 primer is an efficient tool to identify the genetic differences in the fungal races causing leaf blast in rice.
