把带有控制显色的显性等位基因 R 和 I 及控制颜色分布的显性等位基因 Cl、Cv 和 Tr的植株回交,可以选出关于这些等位基因的纯台态杂种。然后进行隔离繁殖,进一步选择,如果不存在
Backcrossing plants with the dominant chromosomally dominant alleles R and I and dominant alleles CI, Cv and Tr that control color distribution allows the selection of purely platform-specific hybrids for these alleles. Then proceed to isolation and breeding, further selection if not present
