Chilean scientists discover new grape varieties: Breakthrough in genetic diversification

Genetic erosion in vineyards is a growing concern in the wine industry, with significant implications for the quality and sustainability of wine production. In Chile, the history of replacing traditional varieties with more common European strains since the 19th century has resulted in a reduction in the genetic diversity of vineyards. To reverse this trend, a group of scientists from the National Institute of Agricultural Research (INIA La Platina) has been dedicated to preserving grapevine germplasm, seeking to identify and characterize ancient varieties still present in traditional vineyards. In a recent study, published in the Australian Journal of Grape and Wine Research, researchers identified 89 grape genotypes from several wine regions in Chile. Of these, 49 presented unique genetic patterns, never before recorded, which represents a significant advance for global viticulture. Furthermore, 10 of these varieties may be descendants of ancient European wines, while 39 show ...
