在用杂交手段选育罐藏黄桃品种的实践中，对果实经济性状的遗传倾向作了分析。结果表明：果实成熟期属数量性状，后代成熟期出现较广泛的分离，但大部分介于双亲之间，在所有的组合中，皆有比例较高的晚于双亲单株，而高比例的早于双亲的后代则出现在成熟期相近的两亲本组合中。由于在有性过程中非加性效应的解体，使得后代果实大小低于亲中值。果实形状的遗传受母本的影响较小，不论其母本果形是圆形、椭圆形，还是扁圆形，后代的果实形状皆以圆形为主。果形由若干位点上若干的主基因控制，增加或减少１个或１对贡献基因，果实形状将向椭圆形或扁圆形变化。果实红色素受母本的影响较大。红色素较高的母本，无论其父本有无红色素，皆出现高比例的果肉红色素后代。由于存在修饰基因的作用，致使果肉质地的遗传中以溶质型后代居多。在个别黄肉亲本的杂交组合中，出现少量白肉的后代 In the practice of breeding yellow peach cultivars by hybridization, the genetic tendency of fruit economic traits was analyzed. The results showed that: the fruit maturity is a quantitative trait, more mature offspring of the offspring of a wide range of separation, but most of the inter-parents, in all combinations, a higher proportion of later than the parent plant, and a high proportion of Offspring older than their parents appear in the combination of two parents with similar maturity. Due to the disintegration of the non-additive effect in sexual process, the fruit size of the offspring is lower than the pro-median value. The shape of the fruit is less affected by the female parent, regardless of whether the female fruit shape is round, oval or oblate, and the fruit shape of the offspring is mainly round. The fruit shape is controlled by a number of major genes at a number of loci, increasing or decreasing one or a pair of contributing genes, and the shape of the fruit will change to oval or oblate. Fruit red pigment is more affected by the mother. The higher maternal red pigment, regardless of whether the male red pigment, all appear a high percentage of the flesh red pigment progeny. Due to the role of modified genes, resulting in the genetic texture of flesh solute-type offspring. In the cross combination of individual yellow-fleshed parents, few white-meat offspring appeared
