Moeminori is a new rice variety suitable for direct seeding cultivation developed at the National Agricultural Research Center for Tohoku Region and registered as Norin 416 by the Ministry of Agriculture, Forestry and Fisheries (MAFF) of Japan in 2006. This cultivar was selected from progenies of the combination Nankai128/Haenuki. One of the parents, Nankai128, is a strain with high eating quality and high-yielding ability, and another, Haenuki, has lodging resistance. The duration to maturity of Moeminori is almost the same as that of Hitomebore and Haenuki and is classified as moderate to late in the Tohoku region. It has complete resistance genes to blast Pia and Pii, while its partial resistance to leaf and panicle are slightly weak and moderate, respectively. Its cool weather tolerance at the reproductive stage is high and its seed dormancy is strong. Its culm length is shorter than that of Hitomebore, and its lodging resistance is greater. In direct seeding cultivation, its root lodging is less than that of Hitomebore and the same as that of Haenuki, and its grain yield is higher than that of both. Furthermore Moeminori shows less lodging and a higher yield even when broadcasted. The translucency of the grain is slightly lower than that of Haenuki, while the whiteness of its polished rice is greater. As for its eating quality, the taste of its cooked rice is excellent, at a level no less than that of Hitomebore. Since it exhibits lodging resistance and high yield potential under a direct seeded condition, it is expected that it can stabilize the yield of direct seeded rice and contribute to the production of rice of excellent eating quality at lower cost in the Tohoku region. It is adapted to the lowland area below middle region of Tohoku of Japan.
