This study was performed in the Research and Training Vineyard of Ankara University, Faculty of Agriculture, Department of Horticulture. In this experiment the effects of five different tying methods [“horizontal form” (←→, 0o ), “vertical form”(↑↑, 90o ), “angled form (45o )”, “arc form”(∩), “loose form” (γ)] of fruiting canes on yield and quality parameters were evaluated on retained ten buds of double Guyot trained Kalecik karası grape cultivars after winter pruning. As a results of the study, the effect on yield parameters such as yield (kg), cluster weight (kg), number of cluster/shoot (n), bud burst ratio (%) and quality parameters such as 100 berries weight (g), total soluble solids (%), titratable acidity (g/l), grape juice pH were determined. The results suggested that angled form and arc form tying methods have positive influence on yield and qualtiy parameters and can be used in practice. 1
