In this work the objective was to determine the productivity of grain and forage of five yellow three-way hybrids compared to white hybrids developed by FESC-UNAM and INIFAP, and the commercial hybrid Buho from Asgrow. Three experiments were planted during 2009; two in CEVAMEX for evaluating grain yield and the other in the FESC-UNAM for evaluating forage production. For yield, the combined analysis detected highly significant differences for hybrids, hybrid trials and interaction x trials (P≤0.01). The coefficient of variation was 17.7 per cent and the overall average of 7,113 kg/ha. The white hybrids Puma 1167 and Puma 1163 had the best grain yielding 9,549 kg/ ha and 8748 kg/ha, respectively. In contrast, the yellow hybrids had a similar performance shown in previous years and represent 136.0% and 112.4% with respect to H-48. The experiment to evaluate forage was planted with a density of 70,000 plants/ha. Puma 1163 and Buho had better forage production (P≤0.05) than the other hybrids evaluated. Hybrid Puma 1163 presented good yields of grain, green forage and dry matter by what could be used in dual purpose, grain and forage production.Downloads
