| 摘 要： | 采用结球甘蓝-大白菜异源三倍体与二倍体结球甘蓝回交的方式,从回交后代BC2中获得了1株2n+1非整倍体植株.经细胞学和SSR鉴定分析,确认该2n+1植株为结球甘蓝8号初级三体.通过对8号初级三体植株自交和回交后代染色体数目的测定,明确了其额外染色体雌、雄配子的传递率分别为34.74％和6.17％.

| Abstract: | In this study,an aneuploid plant with 2n+1 chromosome was obtained from the progeny of cabbage-Chinese cabbage allotriploid backcrossing with cabbage.Cytological and SSR analysis showed that the aneuploid plant was a primary trisomic-8 of cabbage.Furthermore,the chromosome number of the selfing and backcrossing progenies of the primary trisomic-8 plant was identified,and the transfer rate of female and male gametes of extra-chromosome was clarified as 34.74% and 6.17%,respectively. |
