aBin location of QTL was inferred from Oregon Wolfe barley mapping population (Szücs et al., 2009). bCI represents one LOD score drop on either side of the QTL peak. cAbbreviations for markers, S = SCRI_RS, B1 = BOPA1, B2 = BOPA2. dPercentage of phenotypic variance explained by QTL. eEffect of Rasmusson allele, minus sign indicates reduction in the trait value.
