[Author abstract]This experiment was conducted on fertilized paddy field and non-manured paddy field. And the growth responses of rice varieties were compared in relation to their characteristics under both growing conditions. The following results were become evident after this experiment. 1). The characters controlled by vegetative growth, such as number of stems, number of heads, weight of straw per a hill, and as well as heading date, were showed considerable variations on both fields. 2). The panicle weight type varieties adapted advantageously under the non-manured condition, and the panicle number types did under the manured condition, respectively. "Beniasahi", grown and selected on the non-manured condition every years since 1951, showed more satisfactory adaptability in the non-manured paddy field. 3). On non-manured paddy field, it is not necessary to consider the adaptability to heavy fertilizing for selecting of the planting variety.[著者抄録]1.本報告は,無施肥田と施肥田における品種特性の発現程度を比較検討し,両水田における生育反応と品種との関係を明らかにしたものであって,結果の大要は次の様であった。2.施肥の有無によって大きく変動する形質は,1株茎数,1株穂数,出穂日,1株わら重などの栄養体にかかわる形質であった。3.無施肥田では穂重型品種が,施肥田では穂数型品種がそれぞれ収量性は高かった。4.施肥田では,品種の耐肥性が重要な特性となるが,無施肥田では,品種の早晩性が重要な特性となった。5.本実験に用いた6品種中で,ベニアサヒの無施肥田への適応性の高さが注目された。
