1. As the results of comparative cultivation tests of rice plants raised from semi-transparent seeds and opaque ones of each of five glutinous upland strains, it was found that number of days from the date of protrusion of panicle to that of maturation varied in accordance with the differences in the practice of irrigation, and the use of different amount of phosphorus manures supplied, and the disuse of manure. But no constant relations could not be found between transparency of seeds grains and time of maturation. 2.
