Resumo:  Thirty four (9 cultivars and 25 germplasm) genotypes of ash gourd (Benincasa hispida) have been studied to assess the molecular diversity using RAPD markers. A total of 25 RAPD markers produced 163 amplicons, of which 73 % were found polymorphic indicating a high degree of diversity. RAPD based dendrogram showed dissimilarity values from 0.64 to 0.943 also suggesting that the accessions represent a genetically diverse population. The accession IVAG-223 was clearly separated from rest of the accessions based on the RAPD primers. The dendogram revealed that the accessions from northeastern regions of India are different from the accessions of other parts of India, as they cluster together. On the basis of clustering, it was indicated that cultivars had a narrower genetic diversity among themselves as compare to germplasm collected from different agro-ecological region.
