| 摘 要： | 以龙凤鲤、龙凤鲤杂交(第一组)和龙凤鲤、锦鲤杂交(第二组)的93尾子代为实验材料,对所有个体的全长、体高和尾鳍长等10个体型性状指标进行测量,并对结果进行均数差异显著性分析、相关分析和聚类分析。结果表明:两组龙凤鲤的体厚均值存在极显著差异(P<0.01);相关分析表明,两组子代的尾鳍长都与体长有极显著的负相关,第二组子代的尾鳍长与体高、头长、尾柄高有极显著的正相关(P<0.01),相关程度最大的是体高(r=0.536),其它体尺间的相关关系因亲本不同而不同。聚类分析得到,第一组子代的体型指标可以聚为三类,第二组子代的体型指标可以聚为五类。两组龙凤鲤在体型性状上有一定区别。

| Abstract: | Ten morpholorgical traits like full length,body height,caudal fin length and other traits were measured for 93 offsprings come from two pair parents.One was Long-feng and Long-feng carp,the other one was Long-feng and Koi carp,All dates were analysised by mean difference analysis,correlation analysis and cluster analysis.The results were as follows: there was significant difference on body width between two groups.Correlation analysis showed that,both two groups had significant negative correlations on caud... |
