| 摘 要： | 采用根尖压片法对薹菜进行染色体数目和核型分析。结果表明：薹菜为二倍体，染色体数2n=20，核型公式为K（2n）=2X=20=7M+2T+St，染色体相对长度组成为2n=20=2L+4M2+4S，染色体组型为2A型。

| Abstract: | The chromosome number and kapyotype analysis of Tai-tsai〔Brassica campestris L. ssp. chinensis（L.）Makino var. tai-tsai Hort〕were studied by using root-tip squashing method in order to obtain accurate cytogenetic information．The results showed that the chromosome number of Tai-tsai diploids is 2n=20，and its karyotype formula is K（2n）=2X=20=7M+2T+St，the composition of relative length of chromosome is 2n=20=2L+4M2+4S，and the chromosome karyotype was 2A． |
