ASSESSMENT OF GENETIC DIVERSITY AMONG SOME EGYTIAN BARLEY CULTIVARS BASED ON SCoT AND ISSR MARKERS
Abstract
DNA molecular markers (ISSR and SCoT) were exploited to investigate the genetic distinction and relationships among six cultivars of Egyptian barley (Giza 123, 124, 126, 132, 135 and 136). SCoT primers outputted a total of 56 bands, 22 bands were polymorphic (39%). In addition, ISSR primers exhibited 66 bands and 33 of these bands were polymorphic (50%). The two markers were proved to be efficient tools in exploiting the genetic divergence among the tested cultivars and establishing specific phylogenetic relationships. Generally, the ISSR gave more polymorphism than SCoT and can be used in cultivar discrimination.
