In 2005, a new variety of tartary buckwheat [Fagopyrum tataricum (L.) Gaertn.], 'Hokuriku 4', which is adapted for cultivation in Honshu, was developed at the Hokuriku Research Center of NARO Agricultural Research Center (NARO/NARC) (formerly, the Hokuriku National Agricultural Experiment Station). 'Hokuriku 4' was selected from the variety 'DATTANSHU (Rotundatum)' preserved in the NIAS Genebank. The times to full flowering and maturity in 'Hokuriku 4' are 4 and 5 days earlier, respectively, than in 'Hokkai T8,' the tartary buckwheat well adapted to growing in Hokkaido. Although the height of full−grown 'Hokuriku 4' plants is approximately 10 cm shorter than that of 'Hokkai T8' plants, the grain yield of these two varieties is almost equal. The level of rutin in the grains of tartary buckwheat is typically higher than that in the grains of common buckwheat, and its level in 'Hokuriku 4' is approximately 80 times that in the 'Toyomusume' variety of common buckwheat.
