摘要： We selected red rape (B. campestris, vegetable) with purple-red leaf as the female parent, the local variety "sinan white rape "(B. campestris) as the male parent to make cross combination, then used the F1 as female parent, youyan 2(Brassica napus L.) as the male parent and recurent parent to make the backcross hybrid. By using self-cross and orthoselection method, we successfully got the rape line (Brassica napus L.)with the vegetable character of purple-red leaf-zigan. The whole plant of this rape line is purrple-red when it is in seeding stage. When it is growing up, the whole plant become green gradually. It is different at the time of becoming green among different lines. The latest time of becoming green is full-blossom stage. The heredity research results of purple-red leaf character showed: purple-red leaf character was controlled by one pair of dominant genes, it was dominant to green leaf character. Purple-red leaf is an important character of morphological markers, it can be used on the test of hybrid purity and genuineness. It can also be used to distinguish the false hybrid in seedling stage, and improve the production security.
