水产养殖巢式设计遗传力计算及其在SPSS上的实现

Calculation of heritability for aquaculture nest design and its implementation on SPSS

巢式设计是水产育种中重要的遗传设计之一,其遗传力计算涉及平方和类型的选择、固定模型或随机模型的选择及模型修改等,如果处理因素纳入顺序不对,则通过SPSS图形对话框操作不能完成巢式设计方差分析。文章以教材数据为例,介绍巢式设计方差分析的基本原理,利用SPSS软件中对话框粘贴程序进行编程,并通过一般线性模型过程进行方差组分估计及遗传力计算操作演示,并对模型选择、平方和类型选择及巢式设计方差分析SPSS编程的必要性等进行讨论说明,可为教学和科研提供实践参考。

Nested design is one of the important genetic designs in aquatic breeding,and the calculation of its heritability involves the selection of squares and types,the selection of fixed or stochastic models,and model modification,etc.If the processing factors are included in the wrong order,the nested design analysis of variance cannot be completed through the operation of the SPSS graphic dialog box.Taking the textbook data as an example,the paper introduces the basic principles of nested design ANOVA,uses the dialog box pasting procedure in SPSS software for programming,and demonstrates the estimation of variance components and the calculation of heritability through the process of general linear modeling,and discusses and explains the necessity of model selection,sum-of-squares type selection,and the programming of nested design ANOVA in SPSS,etc.,which can provide practical references for teaching and scientific research.It can provide practical reference for teaching and research.
