摘　　要：本文调查分析了维多利亚(♂) ×红地球(♀)杂交后代成龄叶、枝条、树势等主要表型测量及观测性状的遗传倾向,结果表明:各类性状遗传变异丰富,差异明显,遗传倾向均不相同。成龄叶锯齿宽度、叶柄长超亲遗传类型较多;成龄叶叶片宽度、叶片大小等表型性状超亲遗传类型较少;成龄叶叶片锯齿长宽比更多倾向于低亲遗传;无果枝数的超亲比例较高;成龄叶上裂刻深度、开叠类型遗传传递力最高;成龄叶上裂刻基部形状的表型遗传主要以亲本类型为主。This paper investigated and analyzed the genetic tendency of the main phenotypic traits measured and observed in the mature leaves, branches and tree vigor of the hybrid progeny between Victoria and Red Earth, which have different genetic predispositions. The leaf width and petiole length of mature leaves were more than those of other phenotypic traits, such as leaf width and leaf size, and the ratio of leaf width and petiole length to leaf width was more than that of mature leaves The inheritance of cleat depth and cleat base of mature leaf was the highest, and the phenotypic inheritance of cleat base shape of mature leaf was mainly parental type.
