Resumo

The evaluation of genotypes in different years allows obtaining information on stability and adaptability to environmental variation, enabled to identify cultivars that show consistent performance year after year and respond to environmental stimulus, which is desirable by the producer. In this context, the aim of this work was to analyze the effects of the genotype x years interaction in the productivity of the wine grape cultivars. For this, five canopy cultivars (Cabernet Sauvignon, Cabernet Franc, Merlo, Syrah and Sauvignon Blanc) combined with two different rootstocks (IAC 766 and Ripária do Traviú) were evaluated, totaling 10 canopy/rootstock combinations. The experiment was carried out in randomized blocks with five replications and a plot consisting of four plants, in the agricultural years 2011 to 2014 at Instituto Agronômico - IAC, Jundiaí - SP. The data from the four years/harvests were evaluated via mixed models, considering the effect of genotypes as random. After verifying the significant effect of the genotypes x years interaction for grape yield, additional biometric procedures were performed to assess the influence of the interaction on the phenotypic plasticity of the grape genotypes, using the GGEBiplot method. The first two components, for grape yield, explained 93.8% of G + GxE. Year A3 (2013) had the smallest vector linked to the Biplot origin, that is, it was the year that contributed the least to the interaction. The year that most discriminated genotypes for grape yield was A1 (2011), being the most efficient for testing genotypes. Genotype 10 (S. Blanc/Ripária do Traviú) contributed the most to the interaction, exhibiting unstable behavior and low productivity. The best yields were observed in genotypes 7 (Syrah/IAC 766) and 3 (C.Franc/IAC 766). Among these, the combination between C. Franc and IAC 766 showed high productivity associated with high stability.
