Novel stable QTLs identification for berry quality traits based on high-density genetic linkage map construction in table grape
Abstract Background Aroma, berry firmness and berry shape are three main quality traits in table grape production, and also the important target traits in grapevine breeding. However, the information about their genetic mechanisms is limited, which results in low accuracy and efficiency of quality b...
