Resumo: | Background and Aims: The development of an efficient clonal selection process requires 25 the study of genotype-by-environment (G×E) interaction. This work aims to evaluate the 26 variability of the G×E interaction among genotypes and to identify the less sensitive ones. 27 Methods and Results: The approach involves the fitting of mixed models to yield data taking 28 into account the correlation induced by the repeated measurements of the same plot over the 29 years. A measure for comparative evaluation of the G×E interaction among genotypes is 30 proposed (Interaction Sensitivity, IS), based on the variance of the values of the empirical best 31 linear unbiased predictors of G×E interaction effects across environments. In all cases studied 32 significant G×E interaction variability was found, and the proposed measure to rank the 33 sensitivity to G×E interaction varied widely among genotypes. 34 Conclusions: The existence of a common contribution shared by all observations made in the 35 same plot was detected, independently of the lag between years. The proposed measure to 36 rank the sensitivity to G×E interaction permitted identification of stable genotypes. 37 Significance of the Study: This work studied G×E interaction problem in the context of 38 grapevine and proposes a measure for the comparative evaluation of the G×E interaction 39 among genotypes |
