Abstract

The corn crop has great importance in the agricultural production of Brazil, offers several purposes and can be cultivated in all regions of the country. The objective of this work was to evaluate the performance of fifty maize genotypes and their yield components under the influence of the growing environment in the Morrinhos - Goiás region, aiming to identify the best material for cultivation in the region. The experiment was installed and conducted at the Federal Institute of Education Science and Technology Goiano - Campus Morrinhos at an altitude of 890 m, with a randomized block design, with two replications, totaling one hundred experimental units. The productivity components evaluated were Plant Length, Spindle Insertion Length, Spindle Length, Spindle Diameter, Thousand Grain Weight, Spike Grain, Grain Size, and Productivity. The commercial materials P3456HX and 30A3PW showed the best averages for plant length, first ear insertion height, ear length, grain per spike, Agricon17027 presented larger ear diameter, JM 2M77 presented a better weight of one thousand grains , grain size, and material with higher productive potential. We can conclude that among the yield components evaluated for the Morrinhos - Goiás region, we observed that we have different maize genotypes with potential that can be grown in the region as JM 2M77, P3456HX, 30A3PW, NTX544 and experimental LEXP17963, LEXP17997, LEXP171000, LEXP17476.
