The objective of the paper was to identify the number of major loci explaining caffeine content in coffee seeds. Investigations were based on previously published results: (1) Caffeine binds to chlorogenic acids in a 1:1 molecular ratio; (2) Between species, the caffeine content is correlated to the chlorogenic acid content; (3) Only a part of chlorogenic acids is bound to caffeine. Especially, the content ratio between caffeine and chlorogenic acids varied between species. For identifying the number of major loci, a quantitative trait locus (QTL) approach was carried out using an interspecific cross between two highly differentiated species-Coffea liberica dewevrei and Coffea pseudozanguebariae, the latter being a caffeine-free species. As main finding,...
