The present invention describes a novel method for producing hybrid seed in any crop plant, as well as reducing contamination by outcrossing and self-pollination. In contrast to traditional seed production methods, the method of the present invention is suitable for the use of any form of male sterility in the female parent plant, as well as the use of isolation distances from unrelated and undesired plants of the same species. It does not depend on the use of male parent plants in close proximity to the target female. This method is optional for male parent pollen, such as that available in a preserved pollen bank, or for male parent pollen, such as that available using real-time recovery from male plants when they become available. Including supply. Desired pollen is supplied to fertile females during periods when germinable pollen from females and from unrelated plants in close proximity is not released. The male pollen to be supplied is preferentially pollinated by the female, and the relatively pure hybrid seed is used in comparison with the case where neither male sterility nor prescribed isolation distance is used using the current hybrid production practice. It's in quantity and lucky timing to produce at a much higher level. Such a lucky timing is a continuous number one or two days before the female parent's pollen becomes germinable and / or before the female parent's pollen or other adjacent plant pollen begins to fly every day. May include the intentional application of pollen to females in the morning.本発明は、任意の作物植物において雑種種子を産生し、その上、異系交雑および自家受粉による汚染も低下させる、新規方法を記載するものである。従来の種子生産方法とは対照的に、本発明の方法は、雌性親植物におけるいずれの形態の雄性不稔の使用にも、同じ種の無関係のおよび望ましくない植物からの隔離距離の使用にも、標的となる雌に近接した雄性親植物の使用にも依存しない。この方法は、保存花粉バンクにおいて入手できるような雄性親の花粉の、またはそれらが入手できるようになったときの雄性植物からのリアルタイム回収を使用して入手できるような雄性親の花粉の、随意の供給を含む。雌からのおよび位置的に近接している無関係の植物からの発芽可能な花粉が放出されていない期間に、所望の花粉が稔性の雌に供給される。供給される雄性花粉は、前記雌に優先的に受粉させ、比較的純度の高い雑種種子を、現行の雑種生産実施を使用して雄性不稔の実施も規定の隔離距離も用いなかった場合よりはるかに高いレベルで生産するような、量および幸運なタイミングでのものである。そのような
