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

Abstract

In this study, it was aimed to detect the differences of genotypes through the measurement of genetic distance in bread wheat genotypes and to show the usability of chromosome mapping for different aims such as breeding programs, elite seed productions. The genetic diversity of 12 bread wheat genotypes bread wheat genotypes (Bozkır, Harmankaya 99, Altay 2000, Yıldırım, Bezostaja 1, Ahmetağa, Müfitbey, Aldane, Es 26, Alperbey, Atay 85 ad Eraybey) was examined through ISSR and IRAP techniques. As fast molecular techniques, ISSR and IRAP methods can be effectively included in breeding programs both for genetic exploration and evaluation and for the protection of elite breeding and production materials. 12 genotypes were classified into two main clusters in the dendrogram produced by using the ISSR and IRAP markers. While Cluster I included Bozkır, Harmankaya 99, Altay 2000, Yıldırım, Bezostaja 1, Ahmetağa and Müfitbey, cluster II included 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 definition of bread wheat genotypes.
