ISSR-derived Molecular Markers for Korean Wheat Cultivar Identification

Abstract

Inter simple sequence repeat (ISSR) is a technique that leads to the development of novel specific molecular markers and relationship analysis between species. In this study, 54 ISSRs were used to develop cultivar-specific DNA sequence characterized amplified regions (SCARs) for Korean wheat cultivars (Triticum aestivum). Using nine of 54 UBC ISSR primers, 16 cultivar-specific fragments were detected among 32 wheat cultivars. Of the 16 primers, 10 successfully amplified targets in 32 cultivars and six novel cultivar-specific markers were finally selected. A total of 13 Korean wheat cultivars (Ol, Dahong, Namhae, Jinpum, Anbaek, Jopoom,Jokyung, Sinmichal 1, Jeokjoong, Dajung, Goso and Joah) were classified by newly developed six SCAR markers. Cultivar-specific markers can be used not only for cultivar fingerprinting but also for marker-assisted selection in wheat breeding program.
