本方法利用遗传学原理 ,根据基因的分离和独立分配规律 ,把两个不同类的单隐性基因纯合体玉米进行杂交 ,在Ｆ 1植株结果穗上选择双隐性基因纯合体籽粒经多代种植直至稳定 ,再取双隐性基因纯合为一亲本与单隐性或多隐性基因纯合体或其它非隐性基因纯合体为另一亲本杂交 ,即可获?

The method uses the principle of genetics to segregate two different types of single recessive gene homozygous maize according to the rules of gene isolation and independent distribution, and selects the double recessive gene homozygous grain on the ear of F 1 plant for several generations Planting until stable, and then take the double recessive gene homozygous as a parent and single recessive or multiple recessive gene homozygous or other non-recessive gene homozygous for another parent, you can get?
