The objective of this research was to evaluate coffee progenies resulted from the crossing of 'Icatu' with 'Catimor' in relation to their production and plant vigor and to select higher quality progenies to advance the breeding program of this population. For this purpose, a randomized complete block design was carried out with four replications and for the analysis of variance, the Split plot temporal arrangement was adopted. Twenty nine progenies plus the Rubi MG 1192 cultivar, used as a control, were evaluated. The yield of beans in bags.ha-1 of six harvests from 2001/2002 to 2006/2007 was evaluated and the plant vigor after the harvest was assessed. The results indicated that the evaluated progenies showed variability mainly for grain yield confirmed by heritability. This condition associated to high bean yields, which reached 62.0 bags.ha-1 and high plant vigor, showed the possibility of selecting outstanding progenies in the studied population.
