Summary

An ample and sufficient genetic variability provides an opportunity for the breeder to solve the current and potential problems of a given species. In the case of Coffea arabica L., the reduced genetic base that gave rise to its cultivation, which made it especially susceptible to pests and diseases, added to the progressive destruction of its habitat in Ethiopia, center of origin and diversity, led to the search for the collection of its genetic resources in the 1960s. The distribution of the collected genotypes to different research centers marked a milestone for the breeding programs, since they significantly enriched the available genetic variability. However, despite their potential, their use has been low and directed towards resistance to coffee rust. Due to its origin, Ethiopian coffee germplasm offers a great possibility for the improvement of other agronomic characteristics of interest. Therefore, the evaluation and characterization processes are key because they allow identifying the genotypes properties, in addition to increasing the value of the conserved genetic resource. The objective of this seminar is to provide information related to the Ethiopian germplasm, its use, characterization and evaluation results, as well as the perspectives for its use in the genetic improvement of coffee in Colombia.
