Abstract Chinese cabbage - head cabbage alien addition lines were middle materials to genetic improvement in Chinese cabbage using good genes of head cabbage, and have important value in genetic theory research and breeding practice. In this study, the mosomic addition line named CO-4-1(Chinese cabbage with 4# chromosome from cabbage) from the progenies of AAC(2n=29)×AA(2n=20)was obtained by cytology identification,observed and investigated the PMC meiosis behavior and the field character of the plants.The obtained alien addition lines would be used to explore the relation between A and C genomes, transmitting good genes to Chinese cabbage, genome directionally widening genetic background of Chinese cabbage and increasing genetic diversity.
