Nigra, B. oleracea and B. carinata belonged to class 2A according to the classification of karyotypes by Stebbins (1971). According to Levitzky's and Stebbin's view, the more asymmetric karyotype a species has, the more evolved it is. Therefore, B. campestris is the furthest evolved species among the elementary species, and B. juncea and B. napus the furthest among the amphidiploid species. Compared with the previous reports, there is no any cytoplasm in the chromosome sample prepared using this protocol which is very useful for the karyotype analysis, as well as the FISH research on Brassica species.

对上述研究结果分析表明:(1)芸薹属复合种是由基本种相互杂交而成;(2)B基因组与A或与C基因组亲缘关系较远,而A和C基因组亲缘关系较近;(3)芸薹属复合种在演化过程中,发生了染色体结构上的重排现象;(4)芸薹属复合种演化过程中,rRNA基因位点发生了减少;所获结果与国外同类报道相比表明:国内的白菜型油菜存在新的rRNA基因位点,即rRNA基因在芸薹属同一物种不同的品种间具有多态性;有关这类研究国内尚未见报道。
