Resumo: dc.description.abstractThe state of Oaxaca is considered an important center of maize (Zea mays L.) diversification; at least 35 breeds have been identified as a consequence of the selection process carried out by producers in different environments. The objective of the research was to evaluate the grain yield of native maize populations in rainfed environments in the Mixteca Alta region of Oaxaca, in order to identify the most stable in yield. Eighteen native maize populations were evaluated in five contrasting environments under a randomized complete block design. A combined analysis of variance was performed. Subsequently, for grain yield, the site regression model (SREG) was applied to study the genotype-by-environment interaction. Stability analysis was done using the GGE biplot. Based on the stability analysis of the 18 native maize varieties evaluated in five rainfed environments, populations 16 (Yanhuitlán), 14 (Jazmín) and 17 (Jaltepec) stood out for their grain yield, with yields of 5.5, 5.49 and 5.7 t ha-1, respectively. These results reflect the yield potential of native maize and its adaptation to the environmental conditions of the region; in addition, it is widely accepted by producers.pt_BR
