Çerezlik karpuz genotiplerinin genetik çeşitliliğinin SRAP markırları kullanılarak belirlenmesi Determination of genetic diversity of edible-seeded watermelon genotypes using SRAP markers

The watermelon (Citrullus lanatus L.) is one of the most commonly grown and consumed vegetables in the world. Some genotypes of watermelon, which have significant variations, have a snack potential due to their seed characteristics. In this study, SRAP (Sequence Related Amplified Polymorphism) marker technique was used to determine the genetic relationship between some edible-seeded watermelon genotypes. A total of 166 bands were obtained in 24 genotypes and the polymorphism rate was calculated as 97.4%. Four main clusters were observed in the cluster analysis. It was determined that genotypes 2 and 7 clustered separately from the others. Structure analysis revealed that the genotypes consisted of two subpopulations. It was concluded that the edible-seeded watermelon genotypes can be genetically differentiated by the SRAP techniques. The results of this study can be used in breeding strategies for the improvement of the edible-seeded watermelon cultivars.
