Conteúdo: 	Coffee is one of Brazilâ€™s main commodities. Among the goals of crop improvement, the search for drought-tolerant materials has stood out, mainly due to the water scarcity of the producing regions. The knowledge of genetic diversity and the morphophysiological analysis of plants allow the identification of genotypes with potential use in genetic improvement. Thus, this study aimed to evaluate the diversity, by morphophysiological characteristics, in 173 genotypes of Coffea canephora, from populations of contrasting crosses regarding the drought tolerance of the breeding program of Incaper, and to identify the relative importance of traits, subsidizing the selection for drought tolerance, based on the factor analysis index (FAI). The experiment was conducted in three evaluation periods, under field conditions without irrigation at the Incaper Experimental Farm of MarilÃ¢ndia, in the state of EspÃ­rito Santo. There was great variability between and within populations, which was affected by the evaluation season. Based on the traits of greater relative importance identified in this work (LL, LW, SLA, LAR, LT, TLA, PBL, CHL, NO3?, TSP, PRO, A, and iWUE), the FAI identified the genotypes 76?Ã—?48???1, 76?Ã—?48???10, 76?Ã—?48???16, 76?Ã—?48???76, 76?Ã—?48???77, 76?Ã—?48???83, 76?Ã—?48???90, 76?Ã—?48???128, 76?Ã—?04???1, and 76?Ã—?04???32 as more promising, from the ideotype of lower LL, LW, SLA, and LAR, and higher LT, TLA, PBL, CHL, NO3?, TSP, PRO, A, and iWUE.
