EVALUATION OF THE SUITABILITY OF SEVERAL CULTIVARS FOR ORGANIC GROWING IN THE VITICULTURAL CENTER OF MURFATLAR

The adaptability of the grape cultivars to the biotic and abiotic environment is one of the decisive factors for their suitability to be grown in organic culture conditions. The correct identification of highly suitable cultivars reduces the risks of important yield losses in difficult climatic years. The studies performed took into account the climatic factors evolution in the period of 2011-2013 as compared to the average values recorded for the 10-year period 1991-2010. The purpose was to identify some grape cultivars with suitable yields and genetic resistance to these changes to be grown in this region with organic viticulture technologies. Our studies show that the eco-pedo-climatic factors recorded during the last years were more favourable for the organic vine growing than in the past. Among the cultivars that proved to be suitable for the organic viticulture in Murfatlar, displaying high or moderate resistance to pests, drought and frost, are 'Cristina', 'Columna', 'Mamaia', 'Cabernet Sauvignon', 'Feteasca neagra' and 'Riesling italian'.
