Resumen
Descripción
Yield, disease tolerance, and climate adaptation are important traits in grapevine genetic breeding programs.Selection for these characteristics causes unpredictable changes in primary and specialized metabolism, affecting the physico-chemical properties and chemical composition of the berries and their processed products, juice, and wine. In this study, weinvestigated the influence of the genetic distance between grapevine genotypes on the chemical signatures of the juices,by integrating comprehensive metabolic profiling to genetic analyses.
