培育无核葡萄品种是美国农业部加利福尼亚州Fresno园艺研究室育种计划中的一个重要部分。无核葡萄的常规育种是用无核品种的花粉授到有核葡萄品种上,但在后代中只有10—15%为无核后代(Weinberger,1979)。有核亲本品种中的无籽率越高,后代中的无核比率也随之增加。因此,有人提出用无核品种相互杂交来得到无核后代则较为有 Breeding of seedless grape varieties is an important part of the USDA Fresno Horticultural Laboratory Breeding Program in California. Conventional breeding of seedless grapes is given to non-nuclear varieties of grapes using non-nuclear varieties of pollen, but only 10-15% offspring are nuclear free (Weinberger, 1979). The higher the seed-free rate in the nuclear parent varieties, the higher the non-nuclear ratio in the offspring. Therefore, it was suggested that the use of non-nuclear varieties to cross each other to obtain nuclear-free offspring is more
