Abstract

Genomic DNA of ten different populations belonging to different eggplant growing regions were analyzed for RAPD profiles, for understanding the intraspecific variation among them. Twenty-five “lepidopteran specific random primers” were used in this analysis, which generated a lotal of 279 markers revealing an average of 10–12 markers per primer in each population. The primers generated polymorphic markers (249), monomorphic markers (35) with a percentage of polymorphism (87.6). The per cent of polymorphism ranged from 46.15–100 for different primers. The results are discussed in relation to the genetic relationship among the ten populations.
