Behavior of new table grape hybrid elite in the climate conditions of the Copou-Iasi Wine Center

Abstract

Improving the table grape assortment is a permanent concern of hoticultural researchers. Through advanced breeding programs are favored the obtaining, introduction and promotion into the vineyards of new genotypes with superior yield and quality and increased biological resistance. The purpose of these approaches is to satisfy current consumer requirements and the growing demand for table grapes on the market. The current study aims to evaluate two valuable hybrid elite for table grapes obtained at Research and Development Station for Viticulture and Oenology Iasi (Copou-Iasi wine center). Adaptation to environmental conditions and grape quality were analyzed based on agrobiological and technological observations. The two hybrid elite showed high productions (up to 20 t/ha), with a marketed production of over 90%. Both genotypes showed significant accumulations of sugars in grapes (196-200 g/L) and high resistance to cryptogamic diseases, indicating a good adaptation to the environmental factors in the growing area.
