Additional Agronomic Information

May have difficulty establishing roots in the first two years. Requires careful nutrition for the roots to become properly established; avoid excess of nitrogen. An important note about F1 hybrids: Seeds taken from hybrid plants will not have the same characteristics as the parent plants. This is called “segregation.” It means that the child plant will not look or behave the same as the parent, with potential losses of yield, disease resistance, quality, or other agronomic performance traits. The variety should only be reproduced through clonal propagation and purchased from trusted nurseries.

Genetics

information Lineage Naryelis (Catimor) x Ethiopian landrace accession "ET06" (CATIE collection)
information Genetic Description F1 Hybrid (Introgressed)
History

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.
