It is,very impotant problem for the seed production to clarify the effe,cts ,of environmental factors on the characters, of rice seeds, phisiologically and genetically, during the, growing and fruiting periods. For the clarification of this problein, we cultivated 3 varietes of the same origin at different localites for 3 years and compafedthem for the characters of their seeds and tested their after effects in regarding to their growth and yields in the next generation in every year. The results may be summarized as follows. 1 It has been confirmed tha:t t'he characters of rice seeds cultivated at , different localities and their seedlings growth in the next generation were remarkably different. 2. In general, the large seeds were produced in the intermountainous regions and in the level lands under the favorable environmental conditions and their plant grovrth in the next generatiori enzymes. wer e remarkable.
