| 摘 要： | 以樱桃番茄圆形自交系W403（P1）和梨形自交系W405（P2）为双亲，构建P1，F1，P2，B1，B2和R6个家系世代群体，应用植物数量性状主基因＋多基因混合遗传模型和经典遗传学方法对该6个世代群体果形指数进行多世代联合分析，结果显示：W403×W405果形遗传符合2对完全显性主基因＋加性-显性多基因模型。B2，B2和F2群体主基因遗传率分别为14．99％，79．05％和79．70％，多基因遗传率分别为5．34％，7．31％和4．89％，说明F2果形表现出较高的主基因遗传率。对W403×W405组合果形性状的改良要以主基因为主，同时注意环境的影响。 |

| Abstract: | W403,a round-shaped,and W405,a pear-shaped var.cerasiforme,were employed to establish six genealogical populations,P1,F1,P2,B1,B2 and F2,the fruit shape index of the populations were analyzed by means of classic genetics and the major gene + polygene mixed inheritance model of quantitative traits.The results showed that,the Fruit shape index was controlled by two completely dominant major gene plus additive-dominant polygene model.Heritability values of the major genes of B1,B2 and F2 population were 14.99%... |
| Keywords: | var cerasiforme Fruit shape index Major gene+ polygene Genetic analysis |
