Molecular marker-assisted selection (MAS) is an effective tool to accelerate production of cultivars with desirable traits in particular with insect resistance (Yencho et al. 2000; Dekkers and Hospital 2002; Ricciardi et al. 2010; Tocho et al. 2011). DNA markers are beginning to be used to identify plant genes for insect resistance or to classify existing resistance genes in major crops (Smith 1989). The purpose of our research was to map resistance genes against Russian wheat aphid, RWA (Diuraphis noxia), greenbug (Schizaphis grminum) and Sipha maydis in different mapping populations of barley and wheat doubled haploid (DH) lines.
