Oochikara is a nonglutinous rice cultivar, which was released in Japan in 1989. It is characterized by its large-sized grains, i.e. 36.0 g/1,000 grains in brown rice, which is approximately 60% heavier than the check varieties in Japan such as 21.5 g of Sachiminori and 22.3 g of Kochihibiki. Oochikara has very high yielding ability, the average yield of which was 7.17 t/ha in brown rice under the experimental conditions during the period of 1984 to 1988. It is resistant to leaf blast disease, but susceptible to bacterial leaf blight and stripe virus. Since its grain and eating qualities as a staple food are rather low, it is expected that Oochikara would be utilized as a raw material for food industry such as rice confectionery.
