Additional Agronomic Information

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 x wild Ethiopian accession "ET26" (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 Centro Agronómico Tropical de Investigación y Enseñanza (CATIE) coffee collection (accession ET26), originally collected in Ethiopia by the ORSTOM/IRD collecting mission. Selection of Nayarita was done by ECOM-CIRAD in Nicaragua.

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.
