| 摘 要： | 以青花菜86101 ×90196组合获得的DH群体和配制的6个联合世代( P1、P2、F1、B1、B2和F2 ) 群体为试材, 采用主基因+多基因混合遗传模型对花球‘荚叶’性状进行了遗传分析。DH群体分析结果表明, 花球荚叶性状的遗传受到2对连锁并具有加性-加性×加性-上位性作用主基因+多基因( E-220模型) 的控制; 经6个世代联合分析结果表明, 花球荚叶性状的遗传受到2对加性-显性-上位性主基因+加性-显性-上位性多基因( E模型) 的控制, DH群体的主基因遗传率为70.80% , B1、B2和F2世代主基因遗传率分别为73.59%、57.70%和87.07%。上述结果表明: 青花菜花球荚叶性状的遗传受到2对主基因+多基因的控制, 主基因遗传率相对较高。

| Abstract: | A double haploid (DH) population and six generations (P_1, P_2, F_1, B_1, B_2 and F_2)derived from a broccoli combination of 86101 and 90196 were used to investigate the inheritance of head-leaf trait in the Brassica oleracea L. var. italica Planch by using mixed major gene plus polygene inheritance model. The results showed that the head-leaf trait was controlled by linked two additive-additive additive-epitasis major genes plus polygene (E-2-0 model) in DH population and by two additive-dominant-epitasis major genes plus additive-dominant-epitasis polygene (E model) in the joint analysis of the six generations, and the major gene heritability were 70. 80%, 73.59%, 57. 70% and 87.07% in the DH, B_1, B_2 and F_2 populations, respectively. The above results showed that the head-leaf trait was controlled by two major genes plus polygene,and the major gene heritability was relatively high. |
