闽香鳢〔乌鳢(♂)×斑鳢(♀)〕遗传生物学研究Ⅰ.子代和亲本形态比较

Study on Genetic Biology of Hybrid [Channa argus (♂)×Channa meculorta(♀)] Ⅰ.The morphological comparison between hybrid and their parents

通过对闽香鳢〔乌鳢 (♂ )×斑鳢 (♀ )〕及其亲本的主要形态分类学鉴定指标进行测量和比较 ,发现闽香鳢的主要形态学性状介于亲本乌鳢和斑鳢之间 ,为中间类型 ,由此初步判断其为亲本的杂合体。并根据臀鳍、背鳍和侧线鳞数设计了鉴别分选图 。

According to measurement and comparison of major morphological taxology indexes between the first filial generations [Channa argus (♂)×Channa meculorta (♀)] and their parents, it turns out that the major morphological taxology characters of the first filial generations are between those of their parents, that is the middle type. As a result, it could be preliminarily deduced that the first filial generations are hybridizations. Then the differentiate selective diagram has been designed according to the number of anal fins, dorsal fins and lateral line scale, which is convenient for comparison of the morphology between the first filial generations and their parents.
