| 摘 要： | 以5个植物学性状不同的萝卜品种为试材,研究了叶形态及根形态的遗传表现。结果表明,萝卜叶型受细胞核内1对基因控制,板叶对花叶为显性;红叶柄对绿叶柄为不完全显性,同时紫红肉基因也会对叶柄色的遗传产生影响;萝卜肉质根长、根粗两个性状均为不完全显性,属细胞核遗传,不受细胞质的影响;绿皮紫红肉的心里美与绿皮或白皮萝卜品种杂交时,皮色表现紫红或浅紫红色,说明紫红肉基因在杂交过程中对皮色也产生了影响,其遗传规律比较复杂;萝卜肉质色的遗传表现为肉质白色×绿色,F1肉质淡绿色;肉质紫红色×白色,F1表现为白肉紫红心。

| Abstract: | The inheritance of leaf and root morphology were studied by use of five varieties.The following results were obtained:The genetic of leaf morphology is controlled by one pair of genes in the nucleus,the platy leaf is dominant on the deep lobated leaf.Red leafstalk is partly dominant on green one,meanwhile purple flesh gene influence on the inheritance of leafstalk color.The root's length and width are controlled by part-dominant genes in the nucleus.When Xinlimei,which has green skin and purple flesh,was crossed with varieties with green or white skin,the skin color of F_1 were purple or light purple.It is indicated that purple flesh gene influence on the inheritance of skin color.When white flesh variety was crossed with green one,the flesh color of F_1 was light green.When purple flesh variety was crossed with white one,the flesh color of F_1 was white with purple core. |
