'Yukinohana' is a new rice cultivar developed from the cross 'Fukei 180' x 'Kakehashi' made in 1995 at Fujisaka Branch of Aomori Agricultural Experiment Station (The present name is Aomori Prefectural Agriculture and Forestry Research Center). The cultivar was intended for an early- maturing variety with cool weather tolerance and low amylose content characteristics. Several characteristics of 'Yukinohana' are as follows; (1) It belongs to the early-maturity group, and its date of maturity is nearly equal to that of 'Kakehashi'. (2) The plants are panicle weight type rather than intermediate with short culm length and nearly equal to 'Kakehasi' in panicle number. (3) It has moderate resistance to lodging, being inferior to that of 'Kakehashi', but the grain yield potential is nearly equal to that of 'Kakehashi'. (4) It has high tolerance to sterility caused by low temperature before heading, being equal to that of 'Kakehasi'. (5) It has the gene of Pia, Pii resistant to blast disease and has high resistance to leaf blast and panicle blast. (6) It has the characteristics of dull endosperm, its color is translucent and hazy white. (7) The amylose content is lower 5 to 12 percent than that of 'Kakehashi', depending on the air temperature during ripening period. (8) The eating quality is superior to that of 'Kakehashi', especially for softness and stickiness.
