Trigonelline inheritance and QTL identification in the interspecific Coffea pseudozanguebariae x Coffea liberica var. Dewevrei cross
Trigonelline alkaloid is present in coffee beans, and during roasting, it gives rise to the major coffee aroma compounds (several alkyl-pyridines and pyrroles). In this study, we investigated the genetic inheritance of trigonelline accumulation in green beans in an interspecific cross between a wild east African species, Coffea pseudozanguebariae (PSE) and the west African species C. liberica var. dewevrei (DEW). Trigonelline content was measured by HPLC in both parental species, F1 hybrids and the reciprocal back-cross hybrids (BCDEW and BCPSE). The results showed that, on average, PSE accumulated twice as much trigonelline as DEW. No year effect or interaction (genotype x year) was recorded. Trigonelline showed high heritability (71%), which meant that the genotypic value could be easily estimated from the phenotypic value. However, the fact that this trait was not additive suggested the possibility of nucleo-cytoplasmic inheritance. This hypothesis was confirmed by: 1) similar levels of trigonelline content in the PSE, F1, BCPSE and BCDEW groups, all having the same maternal cytoplasm, and 2) the location of one nuclear QTL on the G linkage group.
