Analysing genotype by environment interaction in Dutch potato variety trials using factorial regression

摘要: Genotype by environment interaction was investigated for yield data from the official Dutch Variety List trials potato. The set included 64 genotypes 26 environments, where environments consisted of year soil type combinations. Factorial regression models incorporating genotypic and environmental covariates in were used to analyse data. merits factorial compared with those biadditive models. described comparable amounts interaction, but provided a better basis biological interpretation interaction.
