As for this invention, the kind, and the said it is produced the fruit which does not have the seed which is obtained from the plant and the said plant which can produce the fruit which does not have the seed stably over several generations, by the production method and the said production method of the kind which can produce the fruit which does not have the seed simply and securely from the kind which is produced the fruit which does not have the seed which is obtained is offered. Concrete, this invention the process which elects the first filial generation individual which can produce the fruit which from the first filial generation population which is obtained (a) by making with the individual of male sterile system and the individual of parthenocarpy characteristic system breed, possesses the male sterility and parthenocarpy characteristic, does not have the seed, and (b) to the aforementioned first filial generation individual which is elected, in the breeding method of possessing the process which obtains parthenocarpy characteristic and the offspring individual which possesses the male sterility parthenocarpy characteristic of the particular individual and the individual of the fixed line which can maintain the male sterility as the pollen parent by making breed,From the plant which can produce the fruit which features that it is obtained, does not have the seed is offered.本発明は、数世代にわたって安定的に種子の無い果実を生産し得る植物、該植物から得られる種子の無い果実、簡便かつ確実に種子の無い果実を生産し得る品種の作出方法、該作出方法により作出された品種、及び、該作出された品種より得られる種子の無い果実を提供する。具体的に、本発明は、(a)雄性不稔性系統の個体と単為結果性系統の個体とを交配させることにより得られた雑種第一代個体群から、雄性不稔性及び単為結果性を有し、種子の無い果実を生産し得る雑種第一代個体を選出する工程、及び(b)選出された前記雑種第一代個体に、当該個体の単為結果性及び雄性不稔性を維持できる固定系統の個体を花粉親として交配させることにより、単為結果性及び雄性不稔性を有する後代個体を得る工程を有する交配方法により得られることを特徴とする、種子の無い果実を生産し得る植物を提供する。
