Abstract Seeds of cabbage（Brassica campestris L. var. utilis Tsen et Lee）variety‘Youlv 50 tian’was carried by satellite for space flight treatment. Following the traditional breeding selection, we got 3 new cabbage germplasms. By field observation, the 3 germplasms had apparent variation compared with the original species in agronomic traits, including flowering stage, plant type, leaf shape, flower bulb size, etc. No.2 had the biggest variation, and No.3 had the smallest variation. By RAPD analysis, these germplasms got 31 polymorphic bands altogether. The polymorphism of No.2 was the highest, No.1 was the next and that of No.3 was the smallest. The result was consistent with the field observations.
