A cross between Timor Hybrid 832/1 and Caturra. Pedigree selection (selection of individual plants through successive generations) made by the Instituto del Café de Costa Rica (ICAFE). Never officially released by ICAFE.
In the 1970s, the Centro Agronómico Tropical de Investigación y Enseñanza (CATIE) research station in Costa Rica received third generation (F3) progeny of T5175 from the University Federal de Viçosa in Brazil, which had done initial selection on populations created from a cross of Timor Hybrid 832/1 and Caturra at the Centro de Investigação das Ferrugens do Cafeeiro of Portugal (CIFC). Their designation for the cross was H26. In Central America, it was given the designation T5175 (“T” represents Turrialba, where the CATIE research station is based).
