Adaptability of two-shoot training and four-shoot training was investigated in winter and spring croppings, in order to reduce the number of nursery plants in single-truss tomato cultivation. Cultivation period was prolonged in proportion to the number of trained shoots. Fruit yield was slightly reduced by two-shoot training in the winter cropping, but was not affected in the spring cropping. Four-shoot training decreased the fruit number per shoot, resulting in a decline in yield. In addition, frequent occurrence of abnormal fruits was observed in four-shoot training. Training method did not affect the soluble solid contents of the fruits. Thus, two-shoot training showed a similar level of fruit productivity to that of single-shoot training, although the harvest time was delayed to some extent. Two-shoot training could be suitable for single-truss tomato cultivation, where a large number of nursery plants are needed
