Rice cultivar 'Mochidawara' for processing was developed from a cross between 'Hokuriku-mochi 181' and 'Hokuriku 193'. The cross was carried out in 2001 to develop high yield cultivars. The promising line was named as 'Kanto-mochi 243' and distributed to yield performance test in 2008. The superiority of 'Kanto-mochi 243' was confirmed in the performance tests, and applied to official registration as 'Mochidawara' in the Ministry of Agriculture, Forestry and Fishereries in 2010. 'Mochidawara' belongs to a moderate maturation group. Its heading date and ripening stage are 2 days later and 9 days later than those of 'Odorokimochi', respectively. 'Mochidawara' has medium thick culms and fewer panicle number, belongs to a group of panicle weight type. Its grain yield is higher to that of high yielding cultivar 'Odorokimochi'. The resistance to lodging is 'very strong'. Its resistance gene to blast is unknown and its level of field resistance is unknown. The resistance to bacterial leaf blight is 'moderate' and the reaction of rice stripe is 'resistant'. The preharvest sprouting tolerance is 'high'. According to its superior productivity and stability, 'Mochidawara' is expected to play an important role in glutious processing porpose in Japan.
