Determination of genetic divergence in some bread wheat varieties by IRAP and ISSR analyses

In this study, it was aimed to detect the differences of genotypes through the measurement of genetic distancein bread wheat (Triticum aestivum L.) genotypes. The genetic diversity of 12 bread wheat genotypes (Bozkır,Harmankaya 99, Altay 2000, Yıldırım, Bezostaja 1, Ahmetağa, Müfitbey, Aldane, Es 26, Alperbey, Atay 85 adEraybey) was examined through ISSR and IRAP techniques. As fast molecular techniques, ISSR and IRAP methodscan be effectively included in breeding programs both for genetic exploration and evaluation and for the protection ofelite breeding and production materials. 12 genotypes were classified into two main clusters in the dendrogramproduced by using the ISSR and IRAP markers. While Cluster I included Bozkır, Harmankaya 99, Altay 2000 andYıldırım, cluster II included Bezostaja 1, Ahmetağa, Müfitbey, Aldane, Es 26, Alperbey, Atay 85 and Eraybey.Furthermore, the results obtained in this study indicated that ISSR and IRAP methods were effective for the definitionof bread wheat genotypes.
