摘  要:
以奥尼罗非鱼(Oreochromis niloticus×O.aureus)和星洲银罗非鱼(Oreochromis sp.)为材料,胸腔注射PHA及秋水仙素溶液,取头肾细胞经空气干燥法制片。经核型分析,奥尼罗非鱼核型公式为2n=44,6sm+28st+10t,NF=50,星洲银罗非鱼核型公式为2n=44,10sm+20st+14t,NF=54。这两种鱼都具有1对特大的染色体,染色体对的相对长度范围也相似,但未发现中部着丝粒染色体对和异型染色体,它们的核型与已报道的亲代相似。

摘  要:
The karyotypes of of Oreochromis niloticus O.aureus and Oreochromis sp.were examined in renal tissues by using PHA-injection air drying method.After karyotype analysis the karyotype formula 22n=44,6sm+28st+10t,NF=50 was for Oreochromis niloticus O.aureus and the 2n=44,10sm+20st +14,NF=54 one was for Oreochromis sp.The two fishes both had a large and long chromosome pairs and similar relative length of chromosome pairs,their karyotype formulae were similar to those of their parental generation which had been reported,but no metacentric chromosome pairs and heteromorphic chromosomes were not found in the two fishes.
