 note = {'Mizuhonoka', a new low-glutelin brewer' s rice cultivar developed at the Chugoku National Agriculture Research Center for the Western Region (formerly the Chugoku National Experimental Station), is useful for brewing high-quality sake. 'Mizuhonoka' was bred from the progeny of a cross performed in 1995 between LGC1 and 'Hyogokitanishiki' to add the low-glutelin-content trait to the paternal cultivar. The promising progeny line was named 'Tashukei 1000' ; investigations into its use and suitability for brewing began at Kizakura Co. Ltd. in 2000. In 2004, the line was redesignated 'Chugoku-sake 185' and entered adaptability testing. In 2008, it was registered officially as 'Paddy Rice Norin 426' and named 'Mizuhonoka' by the Ministry of Agriculture, Forestry and Fisheries. The following results have been obtained for this cultivar : 1. 'Mizuhonoka' has a heading date that is 7 days later than that of 'Hyogokitanishiki' and equivalent to that of 'Nipponbare'. Its maturity date is 4 days later than that of 'Hyogokitanishiki' and is equivalent to that of 'Nipponbare'. Its maturity is classified as medium-medium in flatlands along the Seto Inland Sea. Its culm length is 86 cm, which is 2 cm shorter than that of 'Nipponbare' and 6 cm longer than that of 'Hyogokitanishiki'. Its panicle length is 2 cm longer than that of 'Nipponbare' and equivalent to that of 'Hyogokitanishiki'. Its panicle number per unit area is less than that of 'Nipponbare', but more than that of 'Hyogokitanishiki'. Plant type of this cultivar is semi-panicle type. Its culms thickness is medium and hardness is slightly soft. Its tolerance for lodging is slightly strong, equivalent to that of 'Nipponbare' and weaker than that of 'Hyogokitanishiki'. The awns are few, very weak, and short. The apiculus is white, and the lemma is light gold. The shattering resistance is strong, and the grains are non-glutinous. 2. The thousand-kernel weight of 'Mizuhonoka' is about 26 g, which is greater than that of 'Nipponbare' but less than that of 'Hyogokitanishiki'. The brown rice appears to have visual quality superior to that of 'Hyogokitanishiki'. 3. Yield of 'Mizuhonoka' in standard fertilized plots at breeding sites was 61.2 kg/a, which is superior to that of either 'Hyogokitanishiki' or 'Nipponbare'. 4. Polishing time is longer than that of 'Hyogokitanishiki' and shorter than that of 'Nipponbare'. The rice cracks more easily than that of 'Hyogokitanishiki' but is more difficult to break than that of 'Nipponbare'. The ratio of white cores is slightly lower than that of 'Hyogokitanishiki'. Total protein content is lower than that of 'Hyogokitanishiki' and higher than that of 'Gin-oumi'. The water-absorption ratio is equivalent to that of 'Hyogokitanishiki'. Application of classical brewing techniques produces an unpleasant odor, but adding enzymes for brewing of sake mash prevents the occurrence of this odor. Application of this technique to rice brewing produced good-quality sake with improved production efficiency with low volume of sake cakes. 5. 'Mizuhonoka' apparently possesses the true resistance gene (Pii) against rice blast, but its field resistance against leaf blast is weak and that against panicle blast is moderate. Its resistance against bacterial leaf blast is weak. Its viviparity is slightly hard. 6. Judging from its maturation characteristics, 'Mizuhonoka' can be grown in regions from Kanto to western Japan.},
