Approximately 250,000 plants of table grapes ( Vitis vinifera L.) are grown in East Java, Bali, and Central Sulawesi provinces of Indonesia, at an elevation of 5-300 meters above sea level. Monthly maximum and minimum temperatures range from 31-33°C and 23-25° C. Optimum annual rainfall is 800 mm with a period of 3-4 dry months. Grapes were introduced into Indonesia by Dutch colonists in the 17th century. The major commercial cultivars grown are Bali 1 ( = 'Alphonso Lavallee'), and Probolinggo Biru (a land race). They are propagated monstly by cuttings and grown on a trellis 2.5 m in height. These cultivars produce 2-3 crops per year in June, October, and February and yield 50 kg/tree or 25 tons/ha/year. The lack of selected adapted superior varieties such as seedless and powdery mildew-tolerant varieties is one of the constraints on the development of viticulture.
