Abstract

También se proveen semillas de maíz hibrido producidos mediante dicho método. Método para reducir el costo de la produccion de semillas híbridas de maíz. Reivindicacion 1: Un método para producir semillas de maíz híbrido que mejora la pureza de las características transgénicas y la pureza del genotipo, caracterizado porque comprende (a) plantar en un campo de produccion de semillas de maíz hibrido en proximidad de polinizacion, semillas de una primera planta de maíz progenitora y una segunda planta de maíz progenitora; (b) dejar que dichas semillas germinen y crezcan hasta obtener plantas, en donde dicha primera planta de maíz progenitora comprende un primer transgén de tolerancia a glifosato y es homocigota para dicho primer transgén de tolerancia a glifosato y dicha segunda planta de maíz progenitora comprende un segundo transgén de tolerancia a glifosato y es homocigota para dicho segundo transgén de tolerancia a glifosato; (c) tratar dichas plantas en dicho campo de produccion de semillas con al menos un tratamiento de glifosato, en donde dicho tratamiento consiste de: (i) una sola aplicacion de glifosato de aproximadamente 0,54 e.a./ac o más en la etapa de crecimiento V8 aproximadamente o posterior; o (ii) dos aplicaciones de glifosato de aproximadamente 0,54-0,75 e.a./ac en las etapas de crecimiento V8-V12 aproximadamente; y en donde dicha primera planta de maíz progenitora tiene tejidos vegetativos y reproductores femeninos tolerantes a dicho tratamiento con glifosato y se vuelve estéril masculina mediante dicho tratamiento con glifosato, y en donde dicha segunda planta de maíz progenitora tiene tejidos vegetativos, reproductores femeninos y masculinos tolerantes a dicho tratamiento con glifosato; (d) dejar que las segundas plantas de maíz progenitoras polinicen las primeras plantas de maíz progenitoras en dicho campo de produccion; (e) cosechar semillas de maíz hibridas producidas sobre la primera planta de maíz progenitora en dicho campo de produccion, en donde, la pureza de características transgénicas y la pureza del genotipo de dichas semillas hibridas producidas mediante dicho método de produccion de semillas híbridas es mayor que en un campo de produccion de semillas hibridas en donde no se utiliza dicho método de produccion de semillas híbridas.
