Heat summation requirements and number of days from budbreak to flowering, flowering to maturity and budbreak to maturity were compared in 13 grape cultivars under subtropical conditions in Antalya. Phenological stages such as budbreak, blooming and maturity were observed for each cultivar for two years. 10 degrees C was accepted as base temperature. Heat summation requirements of cultivars for the period from flowering to maturity were considerably higher than the those for budbreak to flowering. The earliest cultivars were Uslu and Trakya Ilkeren. Heat summation requirement for budbreak to maturity was 1086 degree-days in Uslu and 1088 degree-C.days in Trakya Ilkeren. Number of days varied from 57 to 63 for the period from budbreak to flowering and from 53 to 95 for the period from flowering to maturity.
