Year + region:year + region:location:year + genotype + Trials correspond to locations within regions across Genotype + genotype:year + genotype:year:trial Year:location + genotype + genotype:year + genotype:location + Trials form a factorial structure of locations x The table below, together with the function parameters used in Structure of the environments in the data. Six different types of models can be fitted depending on the To investigate the structure of the genotype by environment data Mixed model analysis of G圎 table of means In practice precision of the output can always be specified by the Note that due to technical restrictions the number of significantĭigits printed in tables throughout this vignette is not always optimal. Modeling of heterogeneity of genetic variances andįor most of the analyses a pdf report can be created automatically,.Mixed model analysis of G圎 table of means.The following types of analysis can be done using statgenG圎: The availability ofįunctions in the package is based on the analyses described in Malosetti, Ribaut, and van Eeuwijk (2013).įurther suggested reading is van Eeuwijk, This vignette describes how to perform the different types ofĪnalysis that are available in the package. Genotype by Environment (G圎) analysis for data of plant breedingĮxperiments with many options for plotting and reporting the results of The statgenG圎 package is developed as an easy-to-use package for
