Introduce Some Grapevine Cultivars (Vitis vinifera) Tolerated To Drought Stress

Identification and using of grapevine (Vitis vinifera) with tolerance to the drought stress is one of the most importance aims in grape breeding programs in Qazvin province. Indirect selection of drought tolerance among varieties on the base of morphological characteristics with update the drought stress tolerance were identified and selected. For this object, a design in RCBD, and 4 replications in grapevine varieties of Qazvin province were done. The studied characteristics were: relative capacity of leaf water, leaf diameter, leaf area index, leaf hair and ripening time. Data were analyzed that genotypes with morphological phenotypes to drought tolerance were Chafteh, Molae and Syah angoor. Then from those genotypes cutting were obtained and planted in nursery for 2 years. Plants were planted in experimental field in RCBD. In the next year those genotypes treated with 4 drought stress treatment. Drought stress treatments were irrigation to end of May, June, July and August. Data from this stage were analyzed with SPSS software and sensitivity index to the drought stress were calculated. Chafteh was known as the best tolerable genotype to the drought stress in Qazvin province.
