“…According to Ramírez et al (2010), the environmental factors influence the growth and development of the plant. In this regard, the environment studied for seed production, Coquimatlan, Colima, shows good conditions to establish the three hybrids; however, the ratios 4:2 and 6:2 have a significant response between the materials and the variables, obtaining a better response from hybrid G3 in ratio 4:2.…”

Objective: To identify optimal sowing ratios, validation of production technology and seed quality in maize hybrids. Design/methodology/approach: Sowing ratios of 4:2 and 6:2 were studied to observe their effect on the genotypes, as well as their quality and response in seed production; this was done by evaluating the following variables: days to male and female flowering, plant and ear height, percentage of ear and seed in cobs, commercial seed yield, thousand seed weight, number of seeds per kilogram, standard germination and hectoliter weight of the seed. An analysis of variance was carried out using a completely randomized design with factorial arrangement and four replications, the experimental unit being furrows of 20 linear meters. Results: Significant differences were detected in the hybrids with respect to the variables and sowing ratios, which specifically influences the weight, size and number of seeds; the hybrid H-386A had the best response to the environment and ratios, exceeding the rest of the hybrids evaluated by 72.92 %. Limitations on study/implications: The interaction of genotype and environment are factors that limit seed production; however, performing evaluations in different environments allows finding stable hybrids with high yields. Findings/conclusions: The generation of knowledge allows us to make decisions regarding crop establishment and quality in seed production lots, being a recommended environment in CIRPAC’s area of influence

El objetivo del presente estudio fue determinar los efectos de la localidad y la densidad de población en la producción de semilla de líneas progenitoras de híbridos de maíz de Valles Altos de México. En el período de 2006 a 2008, en Coatlinchán, Texcoco, Estado de México (2250 msnm) se sembraron 16 líneas progenitoras de los híbridos: H-40, H-48, H-50, H-52, H-64E, H-66, H-68E, H-70, H-72E, H-74E, H-76E y H-78E en dos densidades de población 82 500 y 62 500 plantas/ha en un diseño de Bloques Completos al Azar con tres repeticiones. Hubo diferencias significativas (p≤0,05) entre líneas, densidad de población y años. Las líneas promediaron entre 73 y 78, y entre 82 y 83 días para inicio y floración media masculina y femenina, respectivamente. El rendimiento varió entre 7744 y 1484 kg/ha, con 86 y 14% de semilla grande y peso hectolítrico entre 70 y 57 kg/hl. Con 82 500 plantas/ha se incrementó en 13% el rendimiento de semilla y disminuyó 2,5% el peso de mil semillas, en comparación con 62 500 plantas/ha. Entre años, el inicio y floración media masculina y femenina varió entre tres y cuatro días; en el 2008 el rendimiento y el peso hectolítrico fueron mayores (4427 kg/ha y 71,75 kg/hl), en 2007 hubo 46,93 y 29,59% más semilla grande que en el 2006 y 2008; mientras que en el 2006 el rendimiento fue 25,30% menor al promedio del 2007-2008. Para determinar cuándo y dónde producir semilla híbrida es indispensable conocer la línea, la localidad de producción y la interacción del genotipo con el ambiente.

The present work took place in the central and northern regions of the state of Campeche, Mexico. The grain yield was evaluated in a total of 46 materials, comprising 30 of white grain and 16 of yellow grain. The crop was supplied to a greater extent with rainwater from the months of July to November. The sowing was in trials designed to evaluate grain yield and technology validation lots established for demonstration purposes. To integrate a genetic material into this study, it was a fundamental requirement that it had at least four evaluations considering different locations or years. As a result of the above, it was determined that there are 27 hybrids of white grain and 14 of yellow grain, which constitute options for the producer with which it is possible to obtain yields of 4.1 to 6.0 t•ha −1 and that can make corn a profitable crop under the current conditions of technology application. Of the white grain hybrids, the group formed by SB-309, DK-395, DK-393, DAS-2382, SP-500, DK-390, P4082W, 9209W, P3966W, SORENTO, JC-25, LUCINO, and 9401W was considered as the high productivity stratum, whose average yield is 5.1 to 5.9 t•ha −1. Similarly, in the yellow grain hybrids, the group formed 9107Y, SP-525A, 2B688, DK-7500, P4226A, IMPACT and DK-7088, was considered as the high productivity stratum, whose average yield fluctuated from 5.0 to 5.9 t•ha −1 .
