在小麦高产育种中,矮秆性状的选育是主要目标之一。育种实践说明、小麦矮秆性状经常可以遇到,但并非任何矮生性变异都具有良好的利用价值。目前生产上应用的矮秆材料多属半矮秆类型,其株高一般在75—95厘米左右,具有抗倒、丰产等特点。在遗传上矮秆性状一般由单一主效隐性基因控制,也有的矮秆材料受多对基因控制,并有显 Breeding of dwarf traits in high-yielding wheat is one of the main goals. Breeding practice shows that wheat dwarf traits can often be encountered, but not any dwarfism has good value. Dwarf material currently used in production are mostly semi-dwarf type, the plant height is generally about 75-95 cm, with anti-down, high yield and other characteristics. Genetically dwarfed traits are generally controlled by a single major recessive gene, while others are controlled by multiple pairs of genes, with significant
