Abstract
RAPD markers were developed for octoploid×Tritordeum (amphiploid Hordeum chilense×Triticum aestivum) and its parents. Addition lines were used to identify specific RAPD markers for the Hordeum chilense chromosomes detectable in a wheat background. Twelve RAPD fragments have been cloned, sequenced and converted into STS markers. Eleven of these STSs have maintained both the chromosome specificity and the possibility of detection in a wheat background. The use of these markers in multiplexed PCRs facilitates both the efficient and reliable screening of new addition lines as well as the monitoring of introgression of H. chilense in bread and durum wheat.
