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.

and malting quality trait phenotypes
linkage map and genotype data
scans and thresholds from SIM and sCIM analysis with MQTL for agronomic and
malting quality traits
