Mixed Model for Studying the Stability of Phenotypic Gene Effects

摘要

The statistical model for the experiments repeated with the same set of genotypes at several locations over a period of years is presented. The model has been defined for the statistical analysis of experiments with the same set of genotypes conducted in the completely standarized block design. The methodology of analysis the data from such a series of experiments was applied to the study of gene effects on the basis of doubled haploids population and F_2 and F_3 hybrid generations. Practical application of this approach was shown on an example concerning the interaction of gene effects with environments for coarse extract yield of barley.
