This research work has been conducted in the „Research Vineyard of Table Grape Varieties‟ area of „COMU Dardanos Campus‟ in the years 2012 and 2013 aimed to determine the effects of different level of axillary shoot removal applications on the yield and quality characteristics of the different varieties of Vitis vinifera L. Grape varieties namely, „Yalova İncisi‟, „Cardinal‟, „Yalova Çekirdeksizi‟, „Ata Sarısı‟, „Amasya Beyazı‟ and „Kozak Beyazı‟ were used as material during this research work. High level axillary shoot removal (YDKA), normal level axillary shoot removal (NDKA) and none axillary shoot removal (YDKB) applications were carried out by performing other cultural practices in a standard manner to all grape varieties. As a result of this research, it was noticed that the axillary shoots left on vine stocks made a positive impact on yield and quality characteristics in all grape varieties. YDKB application has led to a significant increase in vine yield especially in the second year of implementation (2013) by raising the overall potential of vine stocks. As far as the YDKA application is concerned, it reduced the yield of table grape by causing a decrease in the potential of vine stock in all grape varieties especially in the second year of research (2013). Consequently, this application in which all of the axillary shoots are taken from the bottom of vine stock is not recommended for any variety of table grapes. In the case of well–organized spraying program, YDKB method of application will contribute to high yield, good quality and early grape production in all table grape varieties.
