摘　　要：以5个茎瘤芥自交系为亲本试材,采用双亲本杂交遗传设计,运用P1、P2、F1、RF1、F2、B1、B27个世代材料,对茎瘤芥营养生长期瘤茎蜡粉的遗传进行了初步研究。结果表明:瘤茎有蜡粉对无蜡粉为显性,由一对核基因控制。Hereditary studies on wax trait of tumorous stem were carried out in P1,P2,F1,RF1,F2,B1 and B2 generations by using 5 self lines as parents during vegetative duration in tumorous stem mustard.The results showed that tumorous stem wax was dominant characters and waxless recessive.Wax vs waxless was controlled by one dominant nuclear gene.
