Résumé
In recent years, significant advances have occurred in the development of genomic tools to help accelerating the genetic improvement of coffee, a perennial crop with high economic importance. The recent conclusion of the complete genome sequencing of Coffea canephora will serve as a reference sequence for use in advanced molecular genetics, applied directly to molecular breeding of this species, such as the establishment of genome-wide selection programs (GWS). In that direction, a population of 1300 C. canephora individuals maintained at the experimental field of Embrapa Cerrados is being currently phenotyped for different traits such as production, vigour, bean morphology and biochemical composition, as well as drought tolerance. A sample of 30 pools of genotypes, comprising the parentals of the population under study as well as representatives of the C. canephora diversity groups have been re-sequenced by Ilumina Hi-seq for SNPs mining. A genotyping platform for coffee is being established and will provide the required tools for association studies. Results of this ongoing study will be presented and discussed.
