Abstract: F₁, F₂, BC₁and BC₂seedswere obtained through crossing, self crossing and backcrossing by Chinese cabbage( Brassica campestris ssp.pekinensis)of yellow and white heading, orange and white heading, two white headings( one of parent s flowers is also white) in order to study the hereditary characteristics of heading colors, flower colors and pertinency between them.Results showed Chinese cabbage heredity of orange and white flower colorswas controlled by pairs of recessive allele.Heading colors of orange and yellow showed differ ent heredity characteristics.Heredity of orange heading was controlled by pairs of recessive allele, while that of yellow heading showed quantity characteristics.F₁, BC₁ and BC₂ of yellow heading separated different white, yellow and middle color heading types.Meanwhile orange heading and orange flower color were linked, that is, orange heading color showed the same flower color and heredity characteristics.While white and yellow heading colors were not linked to flower colors.Therefore, for orange heading F₁, two parents must be orange heading, and for yellow heading F₁, two parents must also be yellow heading.

Key words: Chinese cabbage, Heading color, Flower color, Hereditary characteristics
