Abstract	As part of the genetic improvement, program for Coffea canephora Pierre ex A. Froehner developed by the Agronomic Institute of Campinas, more than 300 coffee elite-plants were selected, all of which were highly productive, rust-resistant, rusticity and produced large beans of high medium-sieve values (16 to 19), in addition to presenting different fruit ripening patterns. The levels of caffeine and trigonelline of 90 Robusta coffee elite-plants (Congolese group), six eliteplants of Congusta coffee and 29 F1 hybrids were determined with the objective to evaluate the variability of these chemical components. Caffeine levels varied from 1,58 % to 2,94 % in Robusta genotypes, 1,92% to 2,61% in Congusta coffee and from 1,65 % to 3,09 % in F1 hybrids of different origins. Trigonelline levels ranged from 0,68% to 1,35% in Robusta coffee 0,93% to 1,13% in Congusta coffee and from 0,56 % to 1,23% in the F1 hybrids analyzed. The results clearly show great variability in the concentrations of caffeine and trigonelline in selected C. canephora, Congusta and F1 A espécie Coffea canephora, conhecida como café robusta, tem importância considerável no mercado mundial, representando cerca de 36% do café comercializado no mundo (Ferrão et al., 2007). O Instituto Agronômico de Campinas vem desenvolvendo diversos materiais de café Robusta do grupo Congolês e café Congusta (C. canephora x C. congensis) agronomicamente superiores, selecionados em ensaios de campo e em coleção do banco de germoplasma. Além de dar hybrids elite-plants and make it possible to identify clones with high or low levels of caffeine, which is of great interest to both consumers and coffee roasters that use robusta coffee in blends of roasted ground coffee or in the manufacture of soluble coffee.
