A process for producing high yield corn with enhanced grain quality traits is disclosed, whereby the seeds of the interlinear hybrid corn with cytoplasm male sterility and the seeds of the normal pollinator hybrid corn having significant economic traits such as high oil or high protein are mixedly planted in a ratio of 4-9:1. In this process, the effect of cytoplasm male sterility on increasement of yield of the grain is fully used, the effect of mere planting of the interlinear hybrid on the degeneration of the grain is successfully avoided and the output-increasing effect gained from heterosis caused by re-crossing interlinear hybrid is utilized. And characters of father hybrid corn, including high oil and other economic characters controlled by major dominant gene or semi-dominant gene, have been expressed by grains of mother interlinear hybrid corn through metaxenia.
L'invention concerne un procédé de grosse production de maïs dont la qualité de la graine est améliorée. Les graines du maïs hybride interlinéaire présentant une stérilité mâle cytoplasmique et les graines du maïs hybride pollinisateur normal présentant une économie substantielle d'huile ou de protéine sont plantées de manière mélangée selon un rapport de 4-9 :1. Ce procédé exploite parfaitement l'effet de la stérilité mâle cytoplasmique sur l'augmentation de la production de la graine est exploité complètement, évitant ainsi la dégénérescence de la graine et met à profit l'effet de l'augmentation de la production dérivée de la vigueur hybride par la réhybridation. Les caractéristiques du maïs hybride mâle, y compris les aspects économiques, régulées par le gène dominant ou semi-dominant, ont été exprimées par les graines du maïs femelle hybride interlinéaire à travers métaxénie.
