We selected this cultivar from a cross between Tashukei 175 and Akenohoshi. Akenohoshi is a high yielding cultivar with numerous setting of grain per each panicle and Tashukei 175 is a high yielding breeding line of long culm and good plant statue. Crossing was carried out in 1987 and the promising progeny line was named as Chugoku 147 at F_8 generation in 1995. Chugoku 147 had been subjected to local adaptability tests and feed tests for livestock since 1996. Chugoku 147 was recognized to be suitable for whole crop silage from its yielding, and feeding value. It was officially registered as Paddy rice Norin No.380 and named Kusanohoshi by the Ministry of Agriculture, Forestry and Fisheries (MAFF) in 2002. The main characteristics of Kusanohoshi are as follows ; 1. Heading date of Kusanohoshi is 13 days later than that of Nipponbare. Its maturity is classified into late maturity in the plain area along Seto Inland Sea. Its lengths of culm and panicle are longer than those of Nipponbare. The panicle number per unit area is less than that of Nipponbare, and the plant type is superheavy panicle type. The culm is thick and hard. Shuttering habit is hard. 2. Its yielding abilities as whole crop and as grain under transplanting cultivation are about 20% and 30% superior to those of Nipponbare, respectively. Under direct seeding cultivation tests, its yielding ability is superior to that of Nipponbare. 3. Kusanohoshi seems to be possessed of the true resistance genes Pita-2 and Pib for blast disease. Its field resistance for leaf blast and for panicle blast are unknown. The resistance level to bacterial leaf blight is high and Kusanohoshi is resistant to rice stripe disease. The lodging resistance of Kusanohoshi is superior to Nipponbare. 4. Total digestible nutrients (TDN) content per dry matter weight of Kusanohoshi is about 60% by nearinfrared spectroscopic analysis, it is similar to that of Nipponbare. As its higher whole crop yield, the TDN yield per unit area (TDN content × whole crop yield) of Kusanohoshi is superior to that of Nipponbare. 5. Its appearance grade of brown rice is inferior to that of Nipponbare and eating quality of Kusanohoshi is also inferior to that of Nipponbare.}, pages = {99--113}, title = {飼料用水稲新品種「クサノホシ」の育成}, volume = {2}, year = {2003}, yomi = {スノハラ, ヨシヒロ and イイダ, シュウイチ and マエダ, ヒデオ and マツシタ, ケイ and ネモト, ヒロシ and イシイ, タクロウ and ヨシダ, タイジ and ナカガワ, ノブオキ and サカイ, マコト and ホシノ, タカフミ and オカモト, マサヒロ and シノダ, ハルミ} }
