Abstract: In order to identify and certify the genotype of a purple Chinese cabbage CMS, and use the purple character - istics in Chinese cabbage, orF138 primerswere used for PCR analysis in 6materials including purple Chinese cabbage CMS, maintainer line 07 -721, F1, 3 back -crossing segregating plants BC1 -1, BC1 -2, BC1 -3.Then the PCR products were cloned, se - quenced and aligned.Results showed 309bp fragments could only be amplified in purple Chinese cabbage CMS, F1, BC1 -1, BC1 -2, BC1-3, excluding maintainer line 07 -721. Alignment results showed orF138 in purple Chinese cabbage CMS was ho - mologous to Ogu CMS in Raphanus sativus and cybrids of Brassica crops with Ra phanus sativus.The identities among them were 99%. E value was 2e -155. Therefore, the purple Chinese cabbage CMS material belongs to an improved Ogu CMS genotype.The application of the CMS genotype and purple genes in the future is discussed.

Key words: Purple Chinese cabbage, Ogu CMS, orF138, Application
