LG, linkage group; L, location of the QTL peak on the LG in cM; CI, confidence interval; %V, percentage of variance explained by the QTL; A S and A G, the additive effects associated with Syrah and Grenache alleles, respectively; D, the global dominance effect.
The column entitled ‘effect’ indicates major effects of the considered locus involved in phenotype variation, satisfying the following condition: (|As| or |Ag| or |D|)/(|As|+|Ag|+|D|) >0.30.
QTLs in bold were significant in the mentioned year but also putative in the other year or in the multiyear analysis (see Supplementary Table S2 at JXB online for details).
