Interspecific rhizogene grapevine varieties for ecological viticulture

Abstract

Following the increasingly pronounced climate changes that have taken place in recent years, there is an acute need to revive the traditional grapevine assortment in order to reduce the influence of harmful phenomenas on grapevine harvests and ensure their stable production in conditions of frequent climate disruptions. Due to the reduced genetic plasticity of Vitis vinifera grapevine species, there is an urgent need of revitalizing the viticultural assortment with new genotypes whose main characteristics are high adaptability to abiotic environmental factors but also resistance and tolerability to some pathogens and pests specific to grapevines.
