  abstract = {{T}he phenotypic and genetic differentiation between the two related {C}offea species ({C}. liberica {H}iern and {C}. canephora {P}ierre) was examined. {T}hese species differed markedly in terms of leaf, inflorescence, fruit and seed characters. {A} genetic map of the interspecific cross {C}offea liberica x {C}. canephora was constructed on the basis of 72 {BC}1 hybrids. {E}ighty-three {AFLP} markers, four inter simple sequence repeats ({ISSR}) and five microsatellites corresponding to {C}offea liberica species-specific markers were mapped into 16 linkage groups. {T}he total length of the map was 1502.5 c{M}, with an average of 16.3 c{M} between markers and an estimated genome coverage of 81%. {T}he two species were evaluated relative to 16 quantitative traits and found to be significantly different for 15 of them. {E}ight {QTL}s were detected, associated with variations in petiole length, leaf area, number of flowers per inflorescence, fruit shape, fruit disc diameter, seed shape and seed length. {R}esults on segregation distortion and the under-representation of particular markers were interpreted in terms of genome differentiation. {T}he implications for the introgression of {QTL}s involved in advantageous morphological traits (number of flowers per inflorescence, fruit and seed shape) are discussed.},
