Table 2 Phenotypic mean, rage and SD of secondary metabolite and yield traits quantified in the progeny of two hop mapping crosses: (i) Hallertauer Magnum × S.B.L. 2/1, grown in Slovenia; and (ii) Nugget × S.B.L. 3/3, grown in New Zealand

From: Quantitative trait loci in hop (Humulus lupulusL.) reveal complex genetic architecture underlying variation in sex, yield and cone chemistry
