 note = {'Tachisuzuka', a new whole-crop rice cultivar for silage use developed at the NARO Western Region Agricultural Research Center, shows high straw yield, high sugar content and high digestibility of fiber. 'Tachisuzuka' was bred from the progeny of a cross performed in 2001 between 'Gokutansui (00kosen11)' and 'Chugoku 147' (the former name for 'Kusanohoshi') to develop a whole-crop rice cultivar with high straw yield for silage use. The short panicle of 'Gokutansui (00kosen11)' was caused by a spontaneous mutation. The hybrid line was bred using a bulk breeding method. A promising progeny line was named 'Tashukei 1072' ; productivity and adaptability tests of strains began in 2007. In 2008, the line was named 'Chugoku-shi 198' and adaptability testing was initiated. In 2010, it registered under the cultivar name 'Tachisuzuka'. The following results were obtained from analyses of this cultivar. 1. The heading date of 'Tachisuzuka' was almost 4 days later than that of 'Kusanohoshi'. Its maturity is classified as 'extremely late' when grown in plains along the Seto Inland Sea. The culm length was 121 cm, which is longer than that of 'Kusanohoshi'. The panicle length was shorter than that of 'Kusanohoshi', and its appearance seems to be even shorter because several rachis branches close to neck node are degenerate as a result of a mutation inherited from 'Gokutansui (00kosen11)'. The panicle number per unit area is much higher than that of 'Kusanohoshi'. 2. Lodging resistance of 'Tachisuzuka' is classified as 'extremely high'. No lodging occurs at the yellow ripening stage, and little lodging was observed in the two-month period following this stage. 3. The whole-crop yield of 'Tachisuzuka' was slightly higher than that of 'Kusanohoshi'. The unhulled rice yield of 'Tachisuzuka' was lower than that of 'Kusanohoshi', and the straw yield of 'Tachisuzuka' was higher than that of 'Kusanohoshi'. 4. No distinct differences in contents of crude protein, crude fat, crude ash, neutral detergent fiber and nonfibrous carbohydrate were observed between 'Tachisuzuka' and 'Kusanohoshi'. The sugar content of 'Tachisuzuka' was distinctly higher than that of 'Kusanohoshi'. 5. 'Tachisuzuka' apparently possesses three true resistance genes effective against rice blast-Pita, Pib and Pi20(t). The field resistance of 'Tachisuzuka' against leaf blast is classified as 'susceptible'. 'Tachisuzuka' showed high resistance to bacterial leaf blight, a response comparable to that of 'Kusanohoshi' and moderate resistance to sheath blight. 'Tachisuzuka' is susceptible to rice stripe virus. The shattering habit of 'Tachisuzuka' is classified as 'resistant', and viviparity is classified as 'resistant'. 6. Based on its growing period, 'Tachisuzuka' is suitable for cultivation in Kanto and west to Kanto regions in Japan.},
