1. Seed yields of a California strain of Ladino white clover were tested for two years, 1962-63, with the same method of culture at thirteen experiment stations distributed over the country. 2. Climatic conditions of the test years were not favourable for seed production; especially in 1963, when heavy snowfall resulted winterkilling of the clover in the North and much rain checked seed setting in the South. 3. The stations where the yield of seed was 500 grams or more per are were located at Kitami (Hokkaido) and Yatsugatake (Nagano Pref.) in 1962, and Sapporo, Aomori and Yatsugatake in 1963. 4. High correlation was found between seed yields and number of flower head in a unit area, and the latter highly correlated with the latitude of the location of seed production except several stations in high altitudes. 5. In Japan, promising districts for the seed production of Ladino clover are Hokkaido, Tohoku and highland in Central Honshu; therefore suitable locations for obtaining good yield of seeds will be found in these districts with the number of flower head as indicator of seed productivity.
