The variety, non-glutinous, belongs to the middle-to-middle maturing group like Mine-asahi. The plant is of the partial panicle weight type. It possesses medium culms, medium panicles of a medium number, middle high stability in yielding. The kernel size is of the medium to medium long group with good appearance. The eating quality is excellent, comparable to Mine-asahi and Koshihikari. 2. The variety has very high field resistance to rice blast, which was not observed in known major paddy rice varieties in Japan, and we are able to grow the variety in middle area of Japan, without using agrochemicals for control of rice blast.
