This study was designed to select grape varieties suitable for cultivation by beginners in a rural work experience program. Five grape varieties, 'Campbell Early', 'Red Port', 'Steuben', 'Muscat Bailey A', and 'Neo Muscat', were compared for ease of cultivation and fruit productivity. The vines were grown in 10-liter containers during the 1st year and in 50-liter containers during the 2nd-3rd years, under condition of shelter from rain. They were trained by unilateral horizontal cordon training with spur pruning. The uniform shoot growth of 'Red Port' and 'Steuben' was well suited to pattern working. The weaker shoot growth of 'Muscat Bailey A' meant that less labor was needed for shoot management. After 2nd year the shoots of all varieties, apart from 'Neo Muscat', bore flower clusters. The greater berry setting proportion of 'Steuben' gave rise to compact and well-regulated clusters. More insect pests attacked 'Campbell Early', 'Red Port' and 'Steuben', and it was necessary to control them. More diseases occurred in 'Muscat Berry A' and 'Neo Muscat', but were unimportant and no action was needed. Laborsaving plant protection is likely to be needed for 'Muscat Berry A' and 'Neo Muscat', if grow under rain shelter to inhibit disease. It emerged that, 'Steuben' and 'Muscat Bailey A' were the varieties of grape best suited to cultivation by beginners.
