Résumé
The CATIE International Coffee Collection located in Turrialba, Costa Rica has conserved germplasm of the Coffea genus since 1949. Since then it has made significant contributions to the regional coffee farming. This collection is of world importance due to the genetic diversity it preserves, especially of the C. arabica species. Under the agreement signed in 2006, with the International Treaty on Plant Genetic Resources, its germplasm is considered to be of the public domain. The International Collection is made up of around 2000 accessions of which about 800 are wild materials collected at its center of origin (Ethiopia, Kenya, Tanzania). It has about 900 ancient accessions derived from Typica and Bourbon, as well as introgressed or resulting varieties from a backcross of C. canephora, some selections and mutants. In addition, there is a third group that is made up of about 180 hybrids developed at CATIE. One section of the collection is the so-called “Differentials” in which the materials that show tolerance to certain races of rust and that react differently in the presence of the causal agent are conserved, thus identifying races of the pathogen. Due to the age of the plants, which mostly exceeds 50 years, it was necessary to reestablish and relocate the entire collection. For this, an inventory was carried out to find out which materials are at risk of loss in order to rescue them through grafting and thus reestablish them in a new site. This work will make possible to have greater availability of genetic material to be distributed to the countries that are part of PROMECAFE and to strengthen the installed capacity in each country for the identification of rust races. At the Latin American Coffee Symposium, held in Guatemala in 2019, progress and col laboration strategies were presented for the regional coffee rust platform, under the support of the Central American Program for Integral Management of Coffee Rust PROCAGICA-IICA-EU.
