【摘要】 1973～2003年对我国东北山葡萄抗寒的种质资源(品种、品系)进行种内杂交,并与不抗寒的欧亚种酿造葡萄品种进行种间杂交、回交和重复杂交。共定植34个组合杂种苗,成活5639株。观察5种杂交模式,34个组合5639株杂种(F1,F2)苗的果实成熟期的遗传规律。5种杂交模式果实成熟期(早→晚)排列顺序是:山葡萄×山葡萄≥(山-欧)F1×山葡萄≥山葡萄×欧亚种≥(山-欧)F1×(山-欧)F1≥(山-欧)F1×欧亚种。遗传规律是:山葡萄种内和种间杂交后代(F1,F2)果实成熟期分离,表现为连续分布,倾向于早熟亲本,杂交组合中早熟亲本越多,分离出的早熟单株越多,为多基因控制的数量性状遗传、“早熟基因”有累加效应、呈显性遗传给后代。更多还原

【Abstract】 The intraspecific cross of Vitis amurensis Rupr. and the interspecific cross, back cross and recrossing between Vitis amurensis Rupr.（VA）and Vitis vinifera L.（VV）. were carried out from 1973 to 1998 and a heredity law of fruit mature period was analysed for 5 639 plants survived out of 34 hybrid combinations of five crossing models. The sequence from premature to later maturity of mature period of five crossing models was VA×VA≥（VA×VV）F₁×VA≥VA×VV≥（VA×VV）F₁×（VA×VV）F₁≥（VA×VV）F₁×VV. The fruit mature period showed a continuous distribution and a propensity to premature parents. The more premature parents were in crossing combinations the more hybrid progenies were separated. From the premature gene was a quantitative character inheritance controlled by multigene and showed a cumulative response and a dominant inheritance to progenies.更多还原
