| description | The invention belongs to the technical field of corn cultivation, and discloses a cultivation method of a new hybrid corn variety resistant to high-temperature heat damage. The method comprises the following steps of selecting hybrid corn parents, carrying out first hybridization to obtain F1-generation seeds, removing impurities from the F1-generation seeds, carrying out second hybridization on the F1-generation seeds, carrying out third hybridization to obtain F3-generation seeds, and carrying out selfing on the F3-generation seeds to obtain hybrid corn resistant to high-temperature heat damage. According to the method, the corn with excellent high-temperature resistance is selected as the parents for hybridization, the bred F1-generation and F2-generation seeds are good in high-temperature resistance, and the F2-generation seeds and the high-yield corn are hybridized and selfed, so that the new hybrid corn variety which is high in yield, resistant to high-temperature heat damage, excellent in comprehensive |
