investigation of genetic diversity and relationships of ‘kurdistan’ strawberry to some commercial cultivars using microsatellite markers

in order to evaluate genetic relationship, diversity and possible genetically andphysical mixing of kurdistan cultivar with russian, american and european cultivars acollection of 33 samples including: 20 accessions of cv. kurdistan from different fieldsof kurdistan province, 7 russian and 6 american and european cultivars were analyzedusing 10 molecular markers. result indicated that in each microsatellite locus, between4 to 8 (with an average of 5.5) alleles were seen and polymorphism information contentof loci varied between 0.59- 0.86. using cluster and also factor analysis, cultivars weredivided in to 8 groups: (including 2 main groups of kurdistan cultivar samples andrussian cultivars, the rest of the commercial cultivars were placed in the 4th to 8thgroups. high similarity was obtained between kurdistan cultivar and russian cultivars.in comparison to american and european cultivars, considering historical background,it could mean that kurdistan variety might have been a russian cultivar originally,which has brought to iran in the past. results of this study revealed some cases ofphysical mixing of kurdistan strawberry with other commercial cultivars in growingfields and also a case of mutation of this cultivar.
