In this study, a molecular characterization of the variety of 10 cotton (Gossypium hirsutum L.) was made. 6 iPBS markers based on DNA were used, a total of 36 polymorphic bands were observed and the average polymorphism rate was 77.65%. The average polymorphism value of the markers (PIC) is 0.27, the average genetic diversity (H) values are 0.34, the average Dice similarity ratio is 0.37, the correlation ratio (r) is 0.9026. The genetic relationship between the genotypes was determined using the NTSYS-pc software and was found to vary between 0.0456 and 0.8387. The sum of the first three own values described 71.93% of the total variation. Genotypes have been determined to show molecular variation and the conclusion is that the results of genetic diversity can be used in the planning of future cotton healing studies.

In current study, molecular characterization of 10 cotton (Gossypium hirsutum L.) varieties is performed. There are 6 DNA-based iPBS markers, a total of 36 polymorphic bands were detected and the mean of polymorphism rate was 77.65%. The mean gene diversity (H) of the markers was 0.34 and the mean polymorphism value (PIC) was 0.27. The Dice similarity coefficient value and correlation coefficient was calculated as 0.337 and 0.9026, respectively. Genetic diversity among cotton genotypes using NTSYS-pc software changed 0.0456 and 0.8387. Sum of the first three Eigen value explained 71.93% of the total variation. The cotton genotypes used in this study showed highly molecular variation. It was concluded that results of genetic diversity could be used in the selection planning in future cotton breeding studies.
