Both WLT and QY are positively correlated with grain yield. Thus, there is no conflict between WLT, high QY and grain yield, as also indicated by an inadvertent improvement in WLT by breeding for yield in the Nordic countries. Hence, trait-based selection could be done without any negative effects on grain yield. In fact grain yield would be improved, probably more efficiently, since a wide variety of cultivars could be evaluated and further used as parents [25].
