This study was performed to assess the yield sustainability of some grapevine varieties of Russian, Turkmenistan, and Azerbaijan origin by the univariate parametric method. The yields of 15 grapevine varieties were evaluated in full irrigation and deficit irrigation (60% of field capacity) conditions for two years (overall 4 environments) in Takestan Grapevine Research Station from 2017 to 2019. The experimental design was a randomized complete block with three replications. The training system was bilateral Cordon with 2×3.5 meter space planting and two vines in each experimental unit. The combined fixed model analysis of variance and parametric univariate analysis of yield (environmental variance, coefficient of phenotypic variations, Rick ecovalance, stability variance, stability parameter of regression analysis, stability Eberhart and Russell regression, coefficient of determination and Hanson’s stability parameter) were performed for all varieties. The effects of the environment, genotype × environment and varieties were significant at 1% probability in yield analysis of variance. Muscat Yamtazini had yield stability in five parameters and a higher yield than average.
