摘　　要：通过常规根尖压片报道了桂竹香（Cheiranthuscheiri）的染色体数目和核型公式，2n=12=12m．核型分析表明，桂竹香的核型属于1B型，与芸苔属的白菜型油菜亲缘关系较近．Chromosome number and karyotype formula of Cheiranthus cheiri were reported. According to the results, the karyotype formula of Cheiranthus cheiri was 2n = 12 = 12m. Karyotype analysis indicates that Cheiranthus cheiri was more closely related to Brassica campestris than to other brassicas.
