Abstract
Due to geographical and suitable climate, Iran is one of the most important viticulture regions in the world. Drought is one of biotic stresses limiting the growth and production of plants leading to reduced physiological and biochemical traitss such as photosynthesis and vegetative growth. Vinifera grape cultivars are more tolerant to drought stress and there is a high diversity among genotypes and species. In order to study the adaptability of some Iranian grape cultivars in dryland farming, this research was conducted as a RCBD design in west Azerbaijan provinces (Sardasht region). Cuttings of Rasha, Mambraima, Yaghoti, Askari, Khalili, Kolahdary, Kajangoor, Fakhri, Shahani, Perllete and Flame seedless cultivars was planted in field and trained as head prune training system. After three growing years, some quantitative and qualitative traits such as yield, berry and bunch weight, TSS, cold winter tolerance, viability percent in vineyard and harvest time was recorded. Results showed that Perllete and Flame seedless cultivars had the higher yield in two studied years than other cultivars. Yaghoti, Khalili, Flame seedless and Perllete were the early ripening cultivars, respectively. Based on earliness in ripening, higher yield with better fruit quality for marketing, Khalili, Yaghoti, Perllete and Flame seedless cultivars were superior and may be introduced as adapted and more suitable new cultivars for Sardasht region.
