Genetic screening of Turkish barley genotypes using simple sequence repeat markers.

Thirty-four Turkish barley genotypes were differentiated and identified using barley simple sequence repeat (SSR) markers. Amplification of SSR loci were generated using 17 SSR primers. These SSR primers totally produced 67 alleles ranging from two to six alleles per locus with a mean value of 3.94 alleles per locus. Genetic similarity ranged from 0.507 to 1.000. Maximum genetic similarity was found between Efes-98- Basgül, and among Anadolu-86, Obruk-86, Anadolu-98, Tokak 157/37 and Orza-96. Minimum genetic similarity was between Bolayir and Angora. Although SSR markers cannot classify 34 Turkish barley cultivars based on end use, growth habits and row groups, 27 Turkish barley genotypes could be identified uniquely using 17 SSR primers. These results will are useful proves for protecting breeder's rights and designing new crossings. [ABSTRACT FROM AUTHOR]
