摘要/Abstract

摘要：

因子交配设计在林木遗传育种研究中已经得到广泛应用，然而有关该设计的遗传参数和统计量计算还存在不少问题，这在数据不平衡情况下尤为突出。WinNC2是一个新开发的用于计算因子交配设计遗传模型参数的Windows软件，不但可以处理平衡数据，而且还可以处理不平衡数据。针对3种不同的因子交配设计遗传统计模型，该软件使用线性约束模型理论计算一般配合力和特殊配合力以及其他固定效应，使用方差分量模型计算遗传方差和协方差进而估算遗传力。对于每一个参数估计，WinNC2还给出其标准误和显著性检验统计量；对于多性状数据，WinNC2可以计算父本、母本以及父母本交互水平上2个性状的遗传相关系数及其标准误。WinNC2为林木遗传育种工作者分析因子交配设计试验数据提供了一个界面友好、易于使用的计算工具。

Abstract:

Although a factorial mating design has been extensively applied in forest breeding programs, there exist some problems with the design in calculating the estimates of genetic parameters and some statistics, especially when the experimental data are unbalanced. A newly developed Windows-based software (WinNC2), for calculating model parameters of the genetic factorial mating design, can not only deal with balanced data but also with unbalanced data. For three different factorial mating designs, the software estimates the general and special combining abilities of parents and other fixed effects with the restricted linear model, and calculates the genetic variance components and further the heritabilities with the random effect model. In the mean time, WinNC2 can provide standard errors and statistic tests for each parameter estimate. Furthermore, WinNC2 can also present the genetic correlation coefficient between any two traits at each level of paternal, maternal, and their interaction effects. In summary, WinNC2 is a user-friendly computing tool for forest breeders to analyze genetic models of factorial mating designs.

Key words: factorial mating design, combining ability, variance components, heritability
