Y-trellis was compared to open-center vase to evaluate training systems for reducing tree height of peach. The Y-trellis can restrict tree height to 3.5 m. Tree volume of Y-trellis was one third of that of open-center vase. Optimum tree spacing was considered to be a 4 x 6 m (approximately 40 trees/10a). Y-trellis increased orchard productivity and efficiency. Trees of Y-trellis had better fruit color and higher yields than that of the open-center vase. The Y-trellis needed 7-18% less labor on bagging and harvesting than the open-center vase. Pruning in September is the most important work for the Y-trellis. The pruning reduced the growth of trees and improved light penetration at the lower part of tree. No lateral shoots were observed after the pruning. Number of buds was increased and fruit quality in the following year was improved by this pruning
