Rice Stem borer is an important rice pest in India. In the present study, the genetic variability was analyzed among geographically isolated populations of rice yellow stem borer (YSB) from sixty locations of Odisha using ISSR marker technique. Fifty ISSR primers were screened and eleven ISSR primers were selected on the basis of clarity, usability, and reproducibility of their banding patterns. The 11 primers produced a total of 67 bright and discernible bands, all of which were polymorphic. Three unique bands were identified which will be useful for developing diagnostic markers. Genetic similarity among YSB populations varied from 0.02 to 0.1, indicating that wide genetic variation exists among YSB populations at molecular level. Most of the populations could be uniquely distinguished from each other and grouped into four major clusters at 20 % level of genetic similarity.
