Sažetak
Sustaining and developing of genetic diversity in winter wheat germplasm is one of the main conditions for success in future winter wheat breeding programs. Selection of diverse parents is essential for creation of superior new varieties. Danger of genetic erosion specially exists in smaller breeding programs and selection for limited production area with similar growing conditions. Croatian winter wheat breeding has a long tradition but it is relatively small in comparison with countries with bigger growing areas. Use of SSR markers in evaluating genetic diversity of winter wheat varieties is limited in Croatian breeding programs. Therefore, aim of this study was to evaluate genetic diversity of Croatian winter wheat varieties using SSR markers as a powerful tool for assessing genetic diversity. Sixteen winter wheat varieties, from three Croatian breeding centres were included in the study. They were registered from 1936 until today and they were or they still are grown on the large area. A set of 16 microsatellite markers were used, covering three wheat genomes and 42 chromosomes. A total of 65 loci and 337 alleles were detected with the average number of 5.18 alleles per locus. Grouping of varieties were in accordance with their origin (breeding centre) and pedigree.
