Genetic and phenotypic diversity ofCoffea canephora and Coffea arabusta collections in French Guiana 15/12/2017 Suntory – CIRAD research collaborationagreement Through the use of Sequencing-based diversity array technology – DarTseq method – on a collection of 360 C. canephora and 50 Arabusta composed of known and unknown accessions, 2719 polymorphic SNPs were identified. We used a multivariate analysis using SNP data from reference accessions in order to confirm and further fine-tune the genetic diversity of C. canephora. We identified the genetic origin of the different accessions and classified them in the genetic groups well-known.Conclusions: The genetic characterization based on SNP markers and the phenotypic characterization of the accessions conserved in the French Guiana collection increased our knowledge on the genetic diversity of C. canephora. This information is considered very important for future conservation and development conditions for a breeding program.K
