摘　　要：以216株"富士"×"粉红女士"杂交F1代实生苗为试材,对果实大小、果实形状、果实色泽、风味、成熟期等性状遗传表现进行了研究。结果表明:苹果果皮表色遗传表现为简单的质量遗传,红色遗传表现为多基因控制的数量遗传。果形表现了明显的趋中变异现象,果实大小、可溶性固形物及含糖量呈退化的负向优势,后代群体有劣变趋势。杂交后代果实分别呈现肉质变粗、质地变硬、果汁减少的趋势。双亲晚熟,杂交后代未分离早熟类型,表现双亲遗传优势。Taking 216 hybrid Fa seedlings of ＇Fuji＇ × ＇Pink Lady＇ as test materials,the genetic variation performance ot fruit size, shape, color,flavor,maturity and other characters were studied. The results showed that the inheritance of fruit skin color was simple qualitative heredity and the red showed quantitative heredity which was controlled by many genes. The inheritance trends of fruit shape appeared distinct central variation. The fruit size, soluble solid content and soluble sugar content tended to be less than parental mean, which cling the fruit quality of progenies was poor. The hybrids showed coarser flesh,firmer texture,less juice and smaller core size.
