Sweet cherry (Prunus avium L.), a member of Rosaceae family, is an economically important fruit of the temperate zone. In Iran, various sweet cherry genotypes are grown in different areas. For estimation of genetic diversity, 23 RAPD decamer primers data as well as 23 morphological traits were used on 39 sweet cherry cultivars and genotypes, 28 of Iranian and 11 of foreign origin. Random Amplified Polymorphic DNA (RAPD) data was used for clustering of genotypes using UPGMA method. Based on the results, in some cases, clustering of genotypes by RAPD data was in agreement with morphological data; however, the correlation between the two sets of data was not significant (r = 0.2). The coephenitic coefficients between genotypes varied from 0.43 to 0.83 and the value of calculated polymorphism was 81.7 percent, indicating the presence of a high variation between the studied cultivars. This could be due to the presence of both Iranian and foreign genotypes in the experiment. In the main subcluster, genotypes from both origins were present and some genotypes were showing close relationships. Significant regression associations were found between 7 morphological traits and RAPD markers and some informative markers were found for the traits. Also, in clustering of genotypes good agreements were found between the subclusters and the pollination incompatibility groups reported by other workers. The results showed that RAPD is an effective maker for study of genetic diversity among sweet cherry genotypes.

Iran is one of the important countries for the distribution of Cerasus subgenus species with around 225,000 tons production of cherries. Together with Turkey and USA it has been one among the three leading producers of these fruits. One of the important aims in cherry breeding is developing dwarfing rootstocks with good adaptation with different climates and resistance to biotic and abiotic stresses. A program has been initialized in Iran for breeding and developing new rootstocks for cherries, suitable for climatic and edaphic condition of this country. The present study was conducted under this program to categorize some Cerasus sub-genus wild genotypes and improved cultivars and rootstocks, by using vegetative characters. Conservation of the genetic resources of these species is another important aim of this program. Around 27 morphological parameters were evaluated on 74 genotypes in seven species of this sub-genus from eight provinces of Iran. These consisted of P. avium L., P. cerasus L., P. mahaleb L., P. incana Pall., P. brachypetala Boiss., P. pseudoprostrata Pojark. and P. microcarpa Bioss. Analysis of variance of the studied parameters was significant among genotypes, showing a high level of variability for the characters. Results of simple correlation analysis showed the existence of significant positive and negative correlations among some important parameters such as tree height, tree growth habit, trunk diameter, internode length, growth compactness and leaf area. Also, factor analysis showed that tree growth habit, height, growth compactness, trunk diameter, internode length, pubescence on the leaf upper surface and number of leaf serration per cm constitute the main factors. Effective characters were categorized within six factors and accounted for 77.74 of overall variance. Cluster analysis was performed using these six factors and genotypes in the approximate distance of 13 were divided into six main groups. These groups were divided into several sub-clusters and improved varieties or cultivars were clearly separated from the others. The P. cerasus cultivars and genotypes together with one genotype of the P. avium and improved rootstocks (‘Gisela6’ and ‘Colt’) located in one sub-cluster. Scatter plot analysis using two main factors could also clearly separate the location of genotypes and verified genotypes from each other.
