菜蔬, 花卉類에서 “種子形成 不能 一代雜種(F₁)種子”의 利用

Utilization of Seedlessness in F₁Hybrids of Horticultural Crops

If F₁ hybrid plants of vegetables and flowers produce no seeds, (a) it would be easy to eat in some parthenocarpic vegetables such as watermelon, (b) in hybrid plants of many vegetables and flowers the nutrition going to seed formation would be saved, making the plants more vigorous and prolonging the longevity of the plants, and (c) seedlessness would protect the seedmen who produce excellent hybrid seed, because no rival seedmen would be able to produce the imitation F₁ seed from the original F₁ seed which produce no seed. The detailed methods of how seedlessness can be produced by reciprocal translocation of chromosomes and how it can be utilized were reported previously (1).
