摘　　要：通过传统的敲片、Giemsa染色的方法,首次对果蝇属黑腹果蝇种组的5种果蝇(D.constricta、D.ohnishii、D.ogumai、D.pseudobaimaii、D.tani)染色体的数目和形态进行了分析报道。分析发现:这5个种具有相同的染色体数目(2n=8)和不同的形态。D.pseudobaimaii和D.tani为2V,1R,1D型;D.constricta染色为2V,1R,1D型且其点状染色体难以辨认;D.ohnishii和D.ogumai具有相同形态为2V,2R。另外,还发现核型与亲缘关系之间有一定的对应性。Based on the traditional knocking-slides and Giemsa-staining methods, this paper firstly analyzed the metaphase chromosomes of five species （ D. constricta, D. ohnishii, D. ogumai, D. pseudebaimaii and D. toni ） of Drosophila melonogaster species group. The results show that all of the five species share the same chromosomal numbers （2n=8） but with different typical shapes. D. pseudobaimaii and D. toni share the shape 2V, 1R, 1D; D. constricta shews 2V, 1R, 1 D with unclear recognized dot chromosomes; D. ohnishii and D. ogumai share the same chromosomal shapes 2V,2R. And that between karyotype and phylogenetic relationships are found to be correspond.
