主　　题：Chinese cabbage Translocation line Alien gene Molecular marker Late flowering 

摘      要：Flowering time is an important agronomic trait of Chinese cabbage with late flowering being a primary breeding *** our previous work,we obtained Chinese cabbage-cabbage translocation lines that contained several beneficial cabbage ***-specific molecular markers show that these genes were coming from chromosome C01 of *** this study,we investigated the inheritance of flowering time in a couple of translocation lines and analyzed the transmission rate of molecular markers in the ***,we obtained the late flowering Chinese cabbage-cabbage translocation line‘AT7–4’in which the flowering time was later than that of‘85–1’by about 7 days under 4-week *** on previous studies of the genomes of Chinese cabbage and cabbage,we located the cabbage-specific molecular markers that were closely linked at the top of the chromosome A01 in the F2mapping population generated by self-crossing F1s derived from a cross between the translocation line‘AT7–4’and Chinese cabbage‘14–36’.Five flowering-related genes in the alien fragment were found by functional annotation and their molecular markers were *** study lays the foundation for the future improvement of Chinese cabbage varieties using A-C translocation lines.
