  abstract = {{C}offee species such as {C}offea canephora {P}. ({R}obusta) and {C}. arabica {L}. ({A}rabica) are important cash crops in tropical regions around the world. {C}. arabica is an allotetraploid (2n = 4x = 44) originating from a hybridization event of the two diploid species {C}. canephora and {C}. eugenioides (2n = 2x = 22). {I}nterestingly, these progenitor species harbour a greater level of genetic variability and are an important source of genes to broaden the narrow {A}rabica genetic base. {H}ere, we describe the development, evaluation and use of a single-nucleotide polymorphism ({SNP}) array for coffee trees. {A} total of 8580 unique and informative {SNP}s were selected from {C}. canephora and {C}. arabica sequencing data, with 40% of the {SNP} located in annotated genes. {I}n particular, this array contains 227 markers associated to 149 genes and traits of agronomic importance. {A}mong these, 7065 {SNP}s (82.3%) were scorable and evenly distributed over the genome with a mean distance of 54.4 {K}b between markers. {W}ith this array, we improved the {R}obusta high-density genetic map by adding 1307 {SNP} markers, whereas 945 {SNP}s were found segregating in the {A}rabica mapping progeny. {A} panel of {C}. canephora accessions was successfully discriminated and over 70% of the {SNP} markers were transferable across the three species. {F}urthermore, the canephora-derived subgenome of {C}. arabica was shown to be more closely related to {C}. canephora accessions from northern {U}ganda than to other current populations. {T}hese validated {SNP} markers and high-density genetic maps will be useful to molecular genetics and for innovative approaches in coffee breeding.},
