“The research team used "Honey Pear", "Dangshan Crispy Pear" and their hybrid offspring as materials to identify volatile metabolites in the fruit using HS-SPME-GC-MS technology. The genetic variation of volatile substances in pear hybrid offspring was elucidated, and the key role of ester compounds and related metabolic pathways were clarified. This provides key metabolite markers and theoretical basis for targeted breeding of pear flavor quality.”
