In this study, 86 mestizos and 10 hybrids were evaluated in five locations in Central Mexico in randomized complete blocks with two repetitions per site, considering grain yield (REND), male (DFM) and female (DFF) blooms, plant heights (ALP) and cob (ALM), aspects of plant (ASP) and cob (ASM), stem (PAT), root (PAR) and total (PACA), tillering (PHI), cob rot (PMP) and plants cuatas (PPC). There were highly significant differences between females and between males for almost all variables. The female one presented the highest means for most of the variables. The interaction males x females were highly significant for REND, DFF, ASM, PAT, PHI and PMP. Males with higher grain yield and prolificacy 7, 38, 41, 35, 34, 33, 9, 24, 36, 30, 23, 32, 19, 10; of these 7 and 41 were the latest. All the males showed good aspect of plant and cob as well as similar lodging and tillering. The highest percentage of cob rot appcobed in 41, 30 and 27.
