朝日的半矮生性受隐性主效基因控制,并伴有较多修饰基因,且修饰作用较明显;矮秆黄的半矮生性受微效多基因控制,这两个半矮秆品种在粳稻育种中的利用值得进一步研究。
The semi-dwarfism of Asahia is controlled by the recessive major gene and associated with more modified genes, and the modification is more obvious. The dwarf yellow dwarfism is controlled by the microscopic polygene, and the two semi-dwarf varieties are in japonica rice The use of breeding deserves further study.
