ResumenThis study is designed to evaluate and select the best S1 maize top cross lines to continue their process of inbreeding. Nineteen top crosses samples were examined from three contrasting environments (two places from Tamaulipas and one place from the Central High Valleys of Mexico) during 2008. These S1 lines were derived from native populations of four ecological zones of Tamaulipas; one tester from the High Valleys was used. Some top crosses had high yield as well as favorable agronomic traits, though these varied between environments. Some had better performance in Northern Tamaulipas, mainly the tropical groups 1 and 2 that are from hot and dry climates. In the High Valleys these groups had lower yields compared with the top crosses groups 3 and 4. Group 1, the top cross of I-C3001-2915-2 with high yield in the Central and Northern Tamaulipas environments (2.4 and 5.8 t ha-1, respectively) was outstanding. In the High Valleys, the top crosses from group 3 (from the Tamaulipas Huasteca, a hot, and humid climate zone) had yields of 7.4 to 8.5 t ha-1 and from group 4, the top cross of IV-C4031-2939-5(C) yielded 8.8 t ha-1. The S1 lines being evaluated show potential for those top crosses with better grain yield and earliness, indicating good combining ability. It has been suggested that the S1 lines are better to continue the inbreeding process, planning test crosses and field assessments in the environments where they had better performance.es_ES
