'HARUSHIZUKU' was a two-rowed spring barley (Hordeum vulgare L.) cultivar developed by the Fukuoka Agricultural Research Center by using the pedigree breeding method and released in 2005. 'HARUSHIZUKU', tested as 'KYUSHU NIJO 17', was derived from the cross of 'KYUSHU NIJO 11'/'TOCHIKEI 225'. The heading time of 'HARUSHIZUKU' was one day earlier than standard cultivar 'NISHINOCHIKARA' and maturing was same to 'NISHINOCHIKARA'. Culm and spike length were shorter than 'NISHINOCHIKARA' and exceeded 'NISHINOCHIKARA' and 'NISHINOHOSHI' in producing spike number. 'HARUSHIZUKU' was similar to 'NISHINOCHIKARA' in 1000-grain weight. Percentage of plump grains was slightly less than 'NISHINOCHIKARA'. Grain yield exceeded 'NISHINOCHIKARA' and inspection grade was similar to 'NISHINOCHIKARA'. 'HARUSHIZUKU' had good resistance to barley yellow mosaic virus (BaYMV) type I, III by single recessive gene of rym3 and powdery mildew, and moderately resistant to scab. The resistances to wet injury and pre-harvest sprouting were higher than 'AMAGI NIJO'. The overall pearling quality of 'HARUSHIZUKU' was superior to 'NISHINOCHIKARA' and is suitable as a material for Japanese spirit, "Shochu". Based on yield trials performed in several prefectural experiment station, 'HARUSHIZUKU' was expected to be adapted to plain land of the Kyushu areas in Japan. This cultivar has been registered as a recommended cultivar for Fukuoka Prefecture since 2005 and for Kumamoto Prefecture since 2004.
