Ninety wild barley accessions and 11 cultivated barley lines were fingerprinted using restriction fragment length polymorphisms (RFLP), amplified restriction fragment length polymorphisms (AFLPs), microsatellite (SSR) and resistance gene analogue polymorphisms (RGAPs). The results will be analysed using Jaccards dissimmilarity coefficient, unweighted paired group averages (UPGMA) algorithm and principal component analysis (PCA). This will provide the starting point for the application of Advanced Backcross Quantitative Trait Loci (AB-QTL) analysis in barley which offers the potential to identify new genes from H. spontaneum which can substantially improve the agronomic, physiological and malting quality attributes of Australian barley varieties.
