Genotipurile de viţa-de-vie în raport cu factorii mediului ambiant [Articol]

Abstract

Expected results in improving grapevine can be obtained only when using the technique of directed interspecific hybridization based on crossing genotypes from different eco-geographical areas, thus creating native varieties of grapevine. In this case, the genotype combines the desired properties and characteristics of the parent forms. As a result, the formation of genotypic characteristics necessary for adaptation occurs. The adaptation of the created varieties to extreme environmental conditions is possible only if they have been received as a result of crossbreeding of various species (taxa) of grapevine. Besides possessing high resistance to diseases and pests, these genotypes are characterized by high adaptability to the soil and climatic conditions.
