and three landraces from Sinai (El-Kheroba, El-Sheikh Zuwaid, and Wadi Sedr) were carried out using two molecular genetic markers (RAPD-PCR and ISSR-PCR). The genetic distance between Ten genotype was also estimated from banding patterns Twenty two random primers were used in RAPD revealed 316 bands while 159 bands were detected of ISSR analysis using 10 primers. RAPD analysis among ten genotypes showed 41.77% polymorphism, while ISSR analysis showed 62.02% polymorphism. It was found that, ISSR was a more viable marker than RAPD in the detection of the genetic variability among Hordeum vulgare (barley) varieties. The genetic distance tree was detected using UPGMA based on both molecular markers (RAPD and ISSR) and analysis of combined data.In addition, the Band Shearing index (BSI) factor was calculated shows a marked difference between the ten genotypes, seven cultivars and three landraces of studied Hordeum vulgare where BSI average reach 1.42% with RAPD markers while reaching 0.93 % in ISSR. The obtained data indicated that both RAPD and ISSR markers are efficient in identification and differentiation between selected taxa, but the efficiency of ISSR was the best one. Also, the present results, enhancing the available knowledge of Hordeum vulgare genetic resources in Egypt, which may contribute to their conservation and utilization in breeding programs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
