Abstract: The selfing progenies derived from Chinese cabbage–cabbage monosomic addition line 4 were used as materials,3 plants with 2n = 22 were selected by chromosome counting from 36 selfing progenies,and the results from karyotype analysis showed that the 3 plants were Chinese cabbage–cabbage disomic alien addition line introducing chromosome 4 of cabbage. During reproductive period,the disomic alien addition line plant was represented by weak vigor,ovate and green basal leaves,lanceolate and light green stem leaves,late flowering time,yellow flower petals,smaller floral organ size and decreased number of pollen grains compare with monosomic alien addition line. As well as the rate at which selfed silique and seed were set was lower. The chromosome distribution with 11︰11 at napheⅠ represented 70.59%,and the rate of chromosome distribution with 11︰11︰11︰11 was 69.57% at anaphaseⅡ.

Key words: Chinese cabbage, cabbage, disomic alien addition line, karyotype analysis, characteristics
