Editorial: Coffee: From the field to the cup

used simple sequence repeat (SSR) markers to assess the genetic diversity of wild and cultivated populations of Arabica coffee from the Boma Plateau in South Sudan, which has been suggested as a centre of origin of Coffea arabica species, in addition to Ethiopia. Comparing these populations with accessions from Ethiopia, Yemen, and global cultivars, they confirmed their hypothesis and showed that the wild population analyzed was genetically distinct from Ethiopian Arabica. Because Arabica coffee is an autogamous species, thus with low genetic variability, South Sudan coffee population can be a rich material to be explored in breeding programs.In another paper, Dullo et al. ( 2021) evaluated the genetic accessions found in the coffee germplasm of CATIE International Coffee Collection (CICC) in Turrialba, Costa Rica, which has genotypes from all over the world, including from missions organized by several organizations to collected wild genetic material in Ethiopia. The methodological approach they created for an in-depth assessment of the collection can be used for other collections and help breeding programs.To
