Camparision of wheat-barely disomic addition lines using cytogenetical and molecular markers

Genetic materials such as alien additions and substitutions are valuable genetic resources for both plant breeding and basic research. The objective of this study was determination of genetic diversity in wheat addition lines of Hordeum vulgare L., (2n = 2x =14. cv. Betzes) into the genetic background of bread wheat (Triticum aestivum L., 2n = 6x =24, AABBDD, cv. Chinese Spring) by cytogenetical and molecular markers. Cytogenetical study indicated that chromosomes of 1H, 4H and 5H had the morphological differences with recipient parent and 6H had the morphological similarity with recipient parent. A desirable genetic diversity observed based on ISSR markers between the lines. The primers of IS10 and IS15 showed the best polymorphism between the lines. The studied primers were amplified in barley the most regions of the chromosomes of 2H, 3H and 7H. The proliferation regions by using primers for ISSR marker lower placed on chromosomes of 4H, 5H and 6H.
