The North American Barley Genome Project (NABGP) has supported QTL analysis of malting and agronomic traits in three reference populations of doubled haploid lines derived from the following crosses: Steptoe x Morex; Harrington x TR306; and Harrington x Morex. Steptoe and Morex are six-rowed varieties. Harrington and TR306 are two-rowed varieties. Harrington and Morex, respectively, are the two-rowed and six-rowed malting quality standards for North America. Steptoe and TR306 do not have acceptable malting quality profiles, but they have desirable agronomic attributes.
