For the purpose of developing labor saving cultivation system of the fresh market tomato, the following were examined: multi-shoots training and whole truss-harvesting in single-truss tomato plants.1. To keep the high uniformity of shoot growth and flowering between lateral shoots regardless of the cultivation time, the double shoot-training method which used two lateral shoots developed from first and second node of primary shoot of seedlings was suitable.2. The occurrence of malformed fruit increased, when number of trained lateral shoots were increased.3. By topping and transplanting of seedlings at the same time, it was possible to raise uniformity of the flowering on suppressing the generation of the malformed fruit.4. By utilization of cultivar which did not became soft easily even if ripening and ethephon spraying of 400ppm for the truss before the harvesting, simultaneity harvesting by the bunch take was possible.5. We proposed the laber saving cutivation system of fresh market tomatoes which consisted of main element techniques such as mechanical transplanting of plug seedlings, double-shoots training of single-truss plants, whole-truss harvesting and fruit selection with color sencer.
