  abstract = {{C}offea canephora breeding requires combining sustainable productivity with improved technological and cup quality characteristics. {B}everage quality is a complex and subjective trait, and breeding for this trait is time consuming and depends on knowledge of the genetics of its components. {A} highly variable {C}. canephora progeny resulting from an intraspecific cross was assessed for 63 traits over 5 years. {T}o identify quantitative trait loci ({QTL}s) controlling agronomic, technological, and quality-related traits, a genetic map comprising 236 molecular markers was constructed, and composite interval mapping was performed. {B}everage quality was evaluated in relation to biochemical and cup tasting traits. {QTL}s were identified for almost half of the traits evaluated, with effects ranging from 6% to 80% of phenotypic variation. {M}ost of them present a consistent detection over years. {T}he strongest {QTL}s explained a high percentage of the variation for yield in 2006 (34% to 57%), bean size (25% to 35%), content of chlorogenic acids (22% to 35%), sucrose and trigonelline content (29% to 81%), and acidity and bitterness of coffee beverages (30% to 55%). {R}egions of the {C}. canephora genome influencing beverage quality were identified. {F}ive {QTL} zones were co-localized with candidate genes related to the biosynthesis of the analyzed traits: two genes coding for caffeine biosynthesis, one gene implicated in the biosynthesis of chlorogenic acids, and two genes implicated in sugar metabolism. {T}his is one of the first studies on the identification of {QTL}s combining agronomic and quality traits in coffee. {T}he high variability of quality traits within {C}. canephora and the presence of consistent {QTL}s offer breeders a promising tool to improve coffee cup quality.},
