Twelve variable characters were distinguished allowing the identification of 12 different plastomes. The low sequence divergence observed might suggest that #Coffea$ is a young genus. The results were in contradiction with the present classification into two genera. Additionally, cpDNA inheritance was studied in interspecific hybrids between #C. arabica$ and #C. canephora$, and in an intraspecific progeny of #C. canephora$, using PCR-based markers. Both studies showed exclusively maternal inheritance of cpDNA. (Résumé d'auteur) 076AMEPLA06
