摘要: 通过传统的敲片、Giemsa染色的方法, 本文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。

Abstract: 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. pseudobaimaii and D. tani) of Drosophila melanogaster 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. tani share the shape 2V,1R,1D; D. constricta shows 2V,1R,1D 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.

Key words: genus drosophila, D. melanogaster species group, karyotype, D. montium species subgroup
