Abstract The fertile plants MsfMs of Genetic Male Sterile AB Line‘AB01’of common Chinese cabbage and stably inherited inbred lines of Chinese cabbage with orange color‘Beijing-1’,‘Shandong-1’were used to prepare F1,F2 and BC1.Their head color and stamen fertility were appraised,the inheritance rule of head color and the relations between head color,flower color and fertility were analyzed,how the male sterile genes transferred to Chinese cabbage with orange head was explored.The results showed that head color was controlled by a pair of recessive allele,orange head and orange flower were closely linked or even controlled by the same gene,head color and fertility genes reacted independently,and their fertility genes were both msms.On this basis,it put forward a genetic model that it could use genetic male sterile line of common Chinese cabbage to transfer those with orange head.
