Understanding flavour development in interspecific hybrid grapes and wines

点击翻译按钮获取中文摘要

As climate is changing worldwide, the need for adaptable cultivars capable to produce crops under various biotic and abiotic conditions is expending. However, the occurrence of certain quality traits such as diseases resistance and/or cold adaptation results in major changes in the biochemistry of fruit crops that may impact flavour development and, ultimately, affect fruit quality. Such disparities have been the main limitation to the expansion of interspecific hybrid grapes (IHG) in wine production, despite their suitability for low-pesticide and/or northern wine production.
