STUDIES ON THE BEHAVIOR OF A NEW WINE GRAPE HYBRID ELITE IN THE CLIMATIC CONDITIONS OF THE COPOU-IASI VITICULTURAL CENTER

Abstract

Climatic factors of the ecosystem directly influence the vegetative development of the grapevine, the production obtained, and its quality. Obtaining new genotypes with high ecological plasticity, superior yield and quality, and biological resistance can be achieved by continuously improving the existing assortment of grapevine cultivars. The crossbred of the valuable genitors and the selection of perspective genotypes is a permanent concern of horticultural researchers, in order to satisfy the consumer increasingly selective requirements. The purpose of the current study was to evaluate the adaptation of a new wine hybrid elite ('H.E. 13.1.6') obtained at Research and Development Station for Viticulture and Oenology Iasi to the environmental conditions of the Copou-Iasi viticultural centre (NE of Romania), based on agrobiological and technological observations, and analysis on grape yield and wine quality. The hybrid elite showed high productions (up to 19 t/ha), with significant accumulations of sugars in grapes (>200 g/L) and high resistance to cryptogamic diseases, indicating a good adaptation to the environmental factors of the growing area.
