摘要:
Provided are a plant capable of bearing seedless fruits stably over several generations, a seedless fruit generated from this plant, a method of producing a variety capable of readily and reliably bearing seedless fruits, a variety produced by this production method, and a seedless fruit generated from the thus produced variety. Particularly provided is a plant capable of bearing seedless fruits, wherein the plant is obtained by a crossing method comprising a step (a) of selecting a first filial generation plant which is capable of bearing seedless fruits as well as having a male sterile trait and a parthenocarpic trait from the group of first filial generation plants generated by crossing between a plant of a male sterile line and a plant of a parthenocarpic line, and a step (b) of crossing the thus selected first filial generation plant with a plant of a fixed line which is capable of sustaining the parthenocarpic trait and the male sterile trait of the plant, as a pollen parent, to thereby generate a progeny plant having the parthenocarpic trait and the male sterile trait.
