The objective of the present study was to evaluate the agronomic characteristics of 34 accessions derived from interspecific crosses of the genus Coffea sp. of Caturra and Híbrido de Timor called generically as “Catimores“ from the Germplasm Bank during the 2018-2019 coffee campaign, at the farm “La Génova“ of UNALM. With the data obtained, an analysis of variance and a Duncan test were performed for each variable studied using the Statgraphics program. A multivariate analysis (main components and groupings) was carried out with the NTSYS program, which allowed knowing the characters with a higher degree of variability, as well as the relationship between the accessions. The most outstanding accession in average cherry coffee yield was UNACAF-70 with 265.5 qq/ha and the lowest was presented by the UNACAF-173 accession with 64.5 qq/ha. The average number of harvests was 4, with the second harvest being the most representative. The most outstanding accession in average dry parchment coffee yield was UNACAF-70 with 54.6 qq/ha and the one with the lowest yield was the UNACAF-173 accession with 10.9 qq/ha. The highest rust incidence value was 10.8 % in the UNACAF-141 accession, while no symptoms of the disease were observed in 12 accessions. The accession with the highest level of CBB infestation was UNACAF-137 with 40.3% and the lowest was UNACAF-163 with 1.7%. In the physical quality variable, values between 58.5% and 79.2% were obtained, the highest value corresponding to UNACAF-160. No accession was considered as a specialty coffee according to the SCAA scale. Organoleptic quality scores between 66 and 75.8 were obtained, the highest value corresponding to the UNACAF-11 accession..
