1. Bacterial wilt occured less in Non training than in Standard.
2. Standarb was more resistant to late blight than the other.
3. Yield in Non training was higher than the other.
(2) On the object of selecting the suitable varieties for either eating and maaufacturing, ten varieties of tomato were cultured by ordinary management.
1. Norin No. 2 variety reached highest yield and order of the yield was as followes ; Norin No. 2, Aichi tomato, Best of All, Norin No 1.
2. Marglobe and Sekaiichi were relatively resistant to Fusarium wilt and bacteria canker. Then Aichi and Kurihara were high suspectable for thes ediseases.
