摘　　要：采用腹腔注射秋水仙素,取骨髓细胞制备染色体标本,对无特定病原体京白鸡的核型进行了分析。并根据前10对染色体相对长度、臂比值及着丝点指数的测量结果,与已公布的其它地方鸡品种进行了比较。Ten one-day-old Beijing White chickens were injected proper amount of colchicine by intraperitoneal, then marrow cells were washed out and chromosome specimens were prepared.The karyotypes were analyzed as usual. The result of measured relative lengths,arm ratios and centromeric indexes of the first 10 pairs of chromosomes were compared among other published reports of Chinese native chicken species.
