Abstract: Evaluation of genetic resources of eggplant (Solanum melongena L.) from different geographical areas using molecular markers (RAPD) is of great importance in the breeding process. A total of 90 polymorphic amplified products were obtained from 10 decametric RAPD primers, used to analyse the genetic diversity of 20 genotypes of eggplant (16 local and 4 genotypes of foreign origin). The highest polymorphism was determined using the OPAF-16 primer (70.83%). The number of detected bands ranged from 13 (OPF-04) to 24 (OPAF-16), while the average number of bands per primer was 17.2. The lengths of the amplified fragments ranged from 400 to 9 000 bp. The value of the Jaccard's genetic distance coefficient ranged from 0.095 to 0.35, and the dendrogram constructed using the UPGMA method showed that 16 local and 4 foreign genotypes were grouped into nine groups (clusters). Populations K1, K8/1, K19, K22, K25 and K38 represent genotypes that separated from the others and formed single clusters. The lowest value of the calculated genetic distance was 0.095 between domestic genotypes K13 and K12, which also showed morphological similarity in terms of shape and colour. On the other hand, the highest value of genetic distance was calculated between foreign genotypes K19 and K25 (0.35), K19 and K34 (0.34) and K19 and K38 (0.34). Genetically distinct genotypes identified using RAPD markers could be potential starting genetic material for crossing with other genotypes to obtain new and improved eggplant varieties.
