| 摘 要： | 以菜薹品种‘青露菜心’为材料,采用核型分析和形态学鉴定的方法,从三倍体与二倍体的回交子代中筛选SAT–染色体初级三体。共鉴定了374个回交子代,获得了1株SAT–染色体初级三体。SAT–染色体初级三体生长发育基本正常,但柱头高出雄蕊,（n + 1）雌、雄配子的传递率分别为6.04%和3.20%。

| Abstract: | The flowering Chinese cabbage cultivar‘Qinglu Caixin’was used for the satellite-chromosometrisomic（SAT-trisomic）selection by karyotype analysis and morphological identification from the backcross progeny of triploid（2n = 3x = 30）× diploid parent（2n = 2x = 20）. The results showed that one SAT-trisomic was obtained from the 374 progeny identified by chromosome examination and karyotype analysis. Development of the SAT-trisomic was almost normal,but its stigma was above the stamen. Transmission rate of the extra SAT-chromosome was 6.04% by female gametes and 3.20% by male gametes. |
