摘　　要：采用外周血淋巴细胞培养方法，以及Ｃ－带、Ｇ－带和银染技术，对云南地方猪种撒坝猪、大河猪进行了显带染色体研究测量了各号染色体的相对长度，着丝点指数及臂比，Ａｇ－ＮＯＲｓ定位于７号和１０号染色体撒坝猪、大河猪的Ｇ－带带型与其它家猪相似。C-banding, G-banding and Silver-stained techniques have been use to study the chromosomes of the Saba pig and the Dahe pig(Sus scrofa domestica) The relative length, centromere index and arm ratio of each individual chromosome were measured The G-banding pattern of chromosome in the Saba pig and the Dahe pig are similar to those of other domestic pigs The sites of Ag-NORs are located on the chromosome 7 and 10 of the Saba pig and the Dahe pig The C-banding and Ag-NORs are present polymorphism There are some differences in the C-banding and Ag-NORs between the Saba pig and the Dahe pig
