| 摘 要： | 按常规标准测定了异源四倍体鲫鲤的形态特征，并与二倍体的红鲫和湘江野鲤进行了比较.主要结果如下：异源四倍体鲫鲤的背鳍条Ⅲ，16～19；臀鳍条Ⅲ，5～7；侧线鳞30～34，侧线上鳞为5～7，侧线下鳞为5～8；鳃耙数32～35；下咽齿2行，1.4～4.1；脊椎骨31～33；口须2对；体长为体高的2.23～3.33倍，为头长的2.73～4.60倍；头长为吻长的2.67～4.01倍，为眼径的3.33～5.13倍；尾柄长为尾柄高的0.83～1.32倍.研究表明，异源四倍体鲫鲤形态性状稳定，已形成了一个新的四倍体鱼种群.

| Abstract: | The morphological characteristics of the allotetraploid fi sh were studied by ordinary regulations and were compared with those of Red crucia n Carp (Carassius auratus red var.) and Common Carp (Cyprinus carpio L.). The results were as follows: D.3,16～19; A.3,5～7; scalles in lateral line 30 ～34,scalles above lateral line 5～7，scalles below lateral line 5～8; gill raker 32 ～35; pharyngeal tooth 2, 1.4～4.1; vertebrae, 31～33; body length/body height = 2.33～3.33, body length/head length =2.73～4.60; head length / Lip length =2.67 ～4.01, head length /eye diameter =3.33～5.13; caudal peduncel length/caudal ped uncel height =0.83～1.32. The results indicated that the morphological character istics of the allotetraploid fish were steady. |
