Abstract This study was performed to determine the fruit quality losses in ‘Granny Smith’ and ‘Spur Granny Smith’ apple cultivars grown in continental climate conditions having hot and dry summer months in 2007 and 2009 in Ankara. Full bearing trees of cultivars ‘Granny Smith’ on M9 and ‘Spur Granny Smith’ on MM106 rootstocks were used in the experiment. Fruits were harvested at harvest maturity. Yield, sunburn damage on fruits, skin color, fruit size, fruit firmness, soluble solids content and titrable acidy were determined. The most of the attention was given to year of 2007 because of observed extremely hot and dry summer months in this year, and the data was compared with the data of 2009. The amount of apples affected by sunburn damage was quite large in 2007 that the damage was 47.4% in ‘Granny Smith’ and was 73.7% in ‘Spur Granny Smith’. The results showed that growing quality ‘Granny Smith’ apples in regions having such climates is risky, and it stresses the use of additional protective measures.
