光倒刺鲃不同种群的形态差异分析
Morphological Variation Analysis of Different Spinibarbus hollandi Groups
摘要
Abstract
[Objective]The research aimed to provide the theoretical basis for the selective breeding of Spinibarbus hollandi. [Method] 27 quantitative traits and 22 frame traits of three different groups of Spinibarbus hollandi( North River, East River, Ganjiang River) were analyzed by principal component analysis, clustering analysis and discriminant analysis. [ Result]Three principal components were constructed and their contribution rates were 26.026% , 15.502% and 7. 810% respectively. The cumulative contribution rate was 49. 399%. Three groups of S. hollandi were divided into two groups. The first group was Ganjiang River, while North River and East River were clustered into the second group. The results of cluster analysis and principal component analysis are consistent. Three different groups of S. hollandi could be distinguished by the constructed discriminant formula and the correct ratio of discrimination for the samples was 100%. And the cross validation correct ratio of discrimination was 98.03 %. [ Conclusion ] The research could provide basic materials for population identificastion, germplasm resource protection and subsequent breeding of S. hollandi.关键词
