为了提高 "和平红阳" 中华猕猴桃单位面积产量, 采用25 Gy 60 Co-γ射线处理已开花结果的果枝; 将50~100个带一休眠芽的枝段嫁接于同一成年植株的一年生枝砧上, 从2 600多个接芽萌发枝蔓上发现了3 个结不同形状果实的果枝, 将其中一个结大果的实变体嫁接扩繁成为100株以上的无性繁殖系.大果突变体单果质量比原品种增加15.2%, 其果肉含糖量和维生素C质量分数与原品种相比没有明显差异, 单株产量提高13.4%.%To improve Actinidia chinensis Planch cv.Heping Hongyang yield, the fruit spurs with dor-mant blossom buds were radiated with 25 Gy 60 Co-γ ray, and 50~100 shoot sections with a bud were grafted on annual vines of each stock plant.Three fruit-spurs bearing different shapes of fruits were ob-tained in the vines germinated from over 2 600 grafts, and a larger fruit mutant was selected to propagate into a clone with over 100 plants by top graft.The fruits of the larger fruit mutant were 15.2% larger than those of its original cultivar, its sugar content and vitamin C content were not significantly different from those of its original cultivar, and the fruit yield per plant was 13.4% higher than that of its original culti-var.
