Background and Aims The evaluation of genotype-by-environment interaction the genotypic correlations between important economic traits are two relevant issues methodology grapevine selection that remain insufficiently explored. aim this study is to provide methodological tools to: (i) assess (ii) evaluate genetic their practical impacts on selection. Methods Results A multi-environment analysis for each trait multi-trait analyses were applied correlation pairs traits, respectively. presence...
Abstract The present study is devoted to climate change impact assessment on the phenological development and ripening of cv. Touriga Nacional in Dão Wine Region, Portugal. For this purpose, dates three main stages (budbreak, flowering veraison) two maturity are projected for future periods (2041–2070 2071–2100), under anthropogenic radiative forcing scenarios (RCP4.5 RCP8.5), compared against a baseline period (1991–2020). simulated using models (PDMs) temperature‐based ripeness model...
The grapevine vegetative cycle, which is morphologically described by its phenological stages, strongly determined weather conditions. Phenological models are widely applied in viticulture and based on the assumption that air temperature preponderant environmental factor determines vine development. In this study, development (PDMs) were calibrated validated to simulate several intermediate stages between budbreak veraison for cv. Touriga Nacional (TN) Encruzado (EN) winegrape varieties,...
In the present study, we calibrated and validated thermal models to predict DOY date at which grape maturity index, potential alcohol/total acidity (PA/TA), reaches 0.75 (MS0.75), 1.0 (MS1), 1.5 (MS1.5), 2.0 (MS2) for two grapevine Portuguese varieties, Touriga Nacional (TN) Encruzado (EN), growing in Dão wine region, Portugal. Daily rates of forcing calculated with Sigmoid (SM) function Degree Day (DD) were used. The outcomes show that best performance was obtained heat accumulation...
Since the last decade of century, it is known that many old grapevine varieties are descendants other through natural crossing. Portugal has an important program for conservation representative samples intra-varietal variability all autochthonous varieties, managed by Portuguese Association Grapevine Diversity (PORVID), which makes looking genotypes with dubious identification activity from a perspective its valorisation. This communication presents results molecular analysis 5,000...
