Özet:

In this research, it was aimed to determine the yield and quality characteristics of Bozcaada Cavusu (Vitis vinifera L.) grape variety using Kuntra (Karasakız) and Vasilaki grape varieties as pollinators. In this context average yield (g vinestock–1), cluster width (cm), cluster length (cm), cluster compactness (1–9), cluster weight (g cluster–1), cluster length/width, cluster number (number vinestock–1), berry width (mm), berry length (mm), berry weight (g berry–1), berry length/berry width, number of berry (number cluster–1), average number of seeds (number berry–1), the thickness of grape skin (mm), color of grape skin (L, Chroma and °Hue), total soluble solids (%), pH, acidity (%) and maturity index (TSS% acidity%–1) parameters were investigated. The research was planned as 10 replications with one vinestock in each replication. In the vineyard established with Kuntra variety as pollinator, average yield (2756.1 g vinestock–1), cluster width (10.22 cm), cluster length (13.85 cm), cluster weight (280.16 g cluster–1), berry width (20.73 mm), berry length (23.12 mm), berry weight (6.63 g/berry) and the number of berry (40.36 number cluster–1) of Bozcaada Cavusu grape variety were found to be higher than those from the vineyard established with Vasilaki variety as pollinator. Alternatively in the vineyard established with Vasilaki variety as pollinator, cluster length/cluster width (1.498), berry length/berry width (1.140), the thickness of berry skin (0.086 mm), TSS% (18.17%), pH (3.51) and maturity index (31.42) of Bozcaada Cavusu grape variety were higher than those from the vineyard established with Kuntra variety as pollinator. The higher berry number and average yield of Bozcaada Cavusu grape variety in the vineyard established with Kuntra variety as pollinator relatively delayed the development of berry and maturity. Thus, it was concluded that with the later harvest of the Bozcaada Cavusu grape variety, it could contribute to the extension of the limited harvest period in Bozcaada.
