ABSTRACT: To assess the reaction of maize landrace seedlings to inoculations of Fusarium spp. derived from different geographic origins, inoculations were performed to substrates in which seeds were germinated, and the severity of damage and the degree of resistance and/or tolerance at the seedling stage were later evaluated. In this study, 57 populations of maize were collected in the states of Oaxaca, Puebla, Tlaxcala, Guerrero and Estado de Mexico, Mexico, and at same time five sources of Fusarium spp. inoculum were obtained. The maize collection and inocula were then evaluated in a bi-factorial arrangement of treatments in a randomized complete block design with four replications. Significant differences were observed in the virulence of the isolates from each geographic region (p
