Benigorimo is a new rice cultivar developed at the National Agricultural Research Center for Tohoku Region, NARO, and was registered as "Norin384" by the Ministry of Agriculture, Forestry and Fisheries (MAFF) in 2002. This cultivar was selected from the progenies of the combination of Ouu 331/A5//Ouu 331. "A5", one of the parents, is a local variety of nonglutinous red grain in the Tohoku region, named "Akamuro". "Benigoromo" is characterized as a Japonica type rice with early maturity in the Tohoku region. When compared to the local variery of red grain rice, the culm is shorter, the awn is shorter and the grains are harder to shatter. It has a true resistance gene "Pia" to blast, and the field resistance to leaf and panicle blasts are slightly weak and moderate, respectively. Its cool weather tolerance at the reproductive stage is moderate, and the seed dormancy is also moderate. The grain yields are slightly higher than "Akitakomachi," and the 1000 grain weight is about 25g. The grains have higher dietary fiber, sodium, tannin, catechin, and anthocyanidin content than "Akitakomachi", and the anti-oxidant activity of the grains is high. In eating quality, the taste becomes better when mixed with "Silky Pearl," which is a low amylose content cultivar. Since "Benigoromo" has a large red grains, it can be used for "colored rice" without the need for adzuki beans, colored rice wine, or other additives. It is adapted to fertile lowland areas in the Tohoku region.
