This study was conducted to determine phenological, pomological, and yield of nectarine cultivars (Honeykist, Silver of Rome, Fairlane, Maria Laura, Armking, Orion, Stark Red Gold, Crimson Gold, Summer Super Star and Red Gold) which were grafted on GF 677 rootstock and grown in Sanliurfa ecological conditions, between the years of 2008-2011. Based on the results, the full bloom occurred in the studied varieties between the dates of 16 March - 04 April and harvested on 16 June- 04 September. The average fruit weights of the varieties were determined between 65.84 g (Fairlane) and 143.65 g (Silver Rome), fruit firmness between 2.03 kg cm(-2) (Silver of Rome) and 4.65 kg cm(-2) (Summer Super Star), the amount of TSS between 13.63 % (Stark Red Gold) and 16.97 % (Crimson Gold), and titratable acidity between 0.56 % (Orion) - 1.23 % (Maria Laura). According to the values of the four-years (2008-2011), the highest cumulative yield was determined from Armking as 243.94 kg tree(-1)) and as 226.62 kg tree(-1) from Red Gold. Yield per trunk cross-sectional area at the end of the 8th year was determined as 0.99 kg cm(-2) (Silver of Rome) - 2.88 kg cm(-2) (Stark Red Gold). As a result, fruit ripening of nectarine varieties that occur between the dates of 15 June to 15 July has been found to be superior in terms of fruit yield and quality in Sanliurfa ecological conditions.
