A first-generation (F1) hybrid originating from a cross between rust-resistant Naryelis (a Catimor-type variety) and an Ethiopian landrace from the CATIE coffee germplasm collection (accession ET06).
The variety was created by a consortium including French research institute CIRAD, a regional network of national coffee institutes in Central America (PROMECAFE), and CATIE. It was selected and released in 2010. F1 hybrids in Central America are part of an effort by breeders to increase the genetic diversity of varieties in the region since the traditional American varieties are severely genetically constricted.
Typically, F1 hybrid parents are chosen to be genetically distant from one another; this distance maximizes hybrid vigor, which translates into high yields and overall vigor (for example, tolerance to frost), without losses in cup quality or disease resistance. There are only a handful of F1 hybrid coffee varieties in the world, most developed in the last 10 years, and only recently commercially available to farmers.
