fullfact: an R package for the analysis of genetic and maternal variance components from full factorial mating designs.
Full factorial breeding designs are useful for quantifying the amount of additive genetic, nonadditive genetic, and maternal variance that explain phenotypic traits. Such variance estimates are important for examining evolutionary potential. Traditionally, full factorial mating designs have been analyzed using a two-way analysis of variance, which may produce negative variance values and is not...
متن کاملEstimation of ratio of variance components and optimal diallel cross designs
The results on optimal designs for diallel crosses are based on standard linear model assumptions where the general combining ability effects are taken as fixed. Recently Ghosh and Das (2003) proposed a random effects model that allows one to first estimate the variance components and then obtain the variances of these estimates. In this paper we first propose an unbiased estimate of the ratio ...
متن کاملPartial Diallel Crosses
A diallel cross is a set of all possible matings between several genotypes, which may be individuals, clones, homozygous lines, etc. Such crosses are used to estimate general and specific combining abilities of lines and crosses respectively. For ‘n’ inbreed lines, the possible F1’s are n(n–1)/2, which are to be tested in a suitably replicated randomized design. With facilities available for te...
متن کاملAnalysis of Half Diallel Mating Designs I – A Practical Analysis Procedure for ANOVA Approximation
Monoterpene patterns of different larch species (Larix deci-dua, Larix kaempferi, Larix sibirica, Larix gmelinii). In: Results and future trends in larch breeding on the basis of provenance research. Abstract Procedures to analyze half-diallel mating designs using the SAS statistical package are presented. The procedure requires two runs of PROC VARCOMP and results in estimates of additive and ...
متن کاملfactorial and split-plot statistical designs
factorial and split-plot designs are two statistical procedures used to conduct agricultural field experiments. both designs are used frequently to quantify the main and interaction effects of two or more factors. however, split-plot design is recommended for specific situations depending on major and minor goals of the study, characteristics of the factors, and precision of statistical testing...
