Mobilization and exploration of genetic resources in development of sustainable viticulture in context of restrictive factors

Abstract

The viticulture of the Republic of Moldova, situated at the northern limit of industrial viticulture, during the millennia supports climate risk factors. Grapevine assortment evolved to varieties with advanced resistance to winter conditions and an increased adaptability. The phenomenon of „Climate Change”, documented in recent decades, already manifested by increased frequency and pronounced intensity of adverse conditions (extreme temperatures, drought, etc.), requires us to use, in this context, the presented genetic resources, as well as researching and introducing of existing in the world genetic sources with a potential for broadening the base of resistance to unfavorable factors, preserving and enhancing quality and productivity, competitiveness of viticulture. Biological material created until now, existing genetic resources were found to be promising, and the assortment need diversification, focusing on increasing adaptability and biological resistance.
