摘　　要：[目的]研究油桃果实主要性状遗传倾向。[方法]以红芙蓉×中油桃5号F1群体为试材,对果实大小、果实发育期、果肉颜色、风味等性状进行遗传分析。[结果]果肉颜色遗传符合1对等位基因的分离规律,白肉对黄肉为完全显性,证明两亲本均为杂合体;果实发育期属数量性状,后代出现较广泛的分离,5%的单株成熟期有超亲遗传现象;F1群体果实单果重均值低于双亲,但仍有10.5%的单株单果重超过了双亲;F1群体果实可溶性固形物含量平均值虽低于双亲,也有高达16.1%的单株;F1代中果实具有倾向于甜风味的趋势。[结论]红芙蓉×中油桃5号组合后代出现了果型、可溶性固形物含量及综合性状超越了亲本的优系,亲本红芙蓉和中油5号可作为油桃改良的种质。[Objective] The purpose was to study the inheritance trend of nectarine fruit＇s main characters.[Method] Some fruit characters of the F1 generation population of Hongfurong× Zhongyoutao No.5,such as fruit size,fruit development period,flesh color and flesh flavor,were analyzed.[Result] The fruit flesh color was controlled by a pair of alleles,with white dominant to yellow,showing the parents were both hybrid.The fruit development period of fruit was a quantitative character,generation appeared wildly separated,and 5%of the plants in the F1 generation ripened earlier than the parents.The single fruit weight of the F1 generation population was smaller than those of parents,while that of 10.5%individuals were larger than parents.The soluble solid content of the F1 generation population was lower than that of the parents,while those of some individuals were up to 16.1%.Flesh flavor of the F1 generation population had a tendency of sweet.[Conclusion] Some F1 generation population of Hongfurong× Zhongyoutao No.5 are better than the parents in fruit type,soluble solid content and comprehensive trait,so the parents Hongfurong and Zhongyoutao No.5 may used as elite germplasm to improve nectarine.
