Achoimre:The present investigation proposes: morphologically characterize and evaluate the agronomic behavior of two elite lines and a promising hybrid of hard yellow corn in the EET-Pichilingue, for its subsequent launch to the agricultural market, looking for it to be more economical and profitable for farmers in difference to the other commercial hybrids, which come with their technological package and the profit is small. The work began with identifying the 20 plants to evaluate both the elite and hybrid lines, for their subsequent characterization in the vegetative and reproductive stage, starting from days to the emergency, stem color to the color and type of grain that was proceeded to evaluate after harvest. The results obtained indicate that the elite lines L-21-3-1-1 COM-2 and CML-172 and the hybrid L-21-3-1-1 COM-2 × CML-172 at leaf level have a height that It ranges from 149 to 300.20 cm, the amount of foliage is scarce (100%), the stem is green (100%), the cob insert is located at 111 for the lines and 137 for the hybrid with a excellent to regular coverage, its cylindrical - conical shape, with a length of between 16 to 18 cm, the color of white tusa, with yellow semi-crystalline grains in the case of the male parental and for the orange hybrid and female parental, in a regular layout - irregular and regular - straight. The yield of the lines is lower than the hybrid because when crossing these unrelated inbred lines, the resulting seed produces plants of renewed vigor and with a significantly higher yield than that of either parent, in the case of the lines L-21-3-1-1 COM-2 was 3.47 t.ha-1 of the CML-172 line was 1.22 t.ha-1 and the hybrid was 8.12 t.ha1
