1. The greater part of leaves of 6 varieties among 265 varieties of soybean plant preserved at the Odate Agricultural Improvement Experiment Station of Ministry of Agriculture and Forestry did not fall off even in autumn. 2. It is considered that the non-leaf-fall varieties originated in U.S.A. 3. Through surveying the duration from seeding to flowering and the length of the growing season, I saw that the non-leaf-fall varieties were admitted into the medium and late varieties except one very early Chestnut. 4. The starch was almost entirely absent in the seed and in the main pulvinus at the yellowish leaf stage of non-leaf-fall varieties. But the starch was not found completely in the grain of the other non-leaf-fall varieties. 5. The weight of gains of non-leaf-fall varieties was more light than that of any other varieties in general. 6. The seed coat and the hilum of gains of the non-leaf-fall varieties put on a dark colour.
