内容記述 |
Nikomaru is a new paddy rice variety developed by the National Agricultural Research Center for Kyushu Okinawa Region in 2005. The variety was selected from the cross between Hakei 626 (Kinumusume) and Hokuriku 174 conducted in 1996. Both parents are early-maturing varieties with fine eating quality of boiled rice. The line Izumi 722, selected from the cross at the F_6 generation, was named "Saikai 250" at the F_8 generation. Saikai 250 has undergone local adaptability tests, mainly in Kyushu, since 2002. It was recognized as a medium-maturing variety with fine eating quality, high yield, and tolerance to grain damage caused by high temperature during ripening and was recommended in Nagasaki Prefecture. It was officially registered as Nikomaru (Paddy Rice Norin 410), by the Ministry of Agriculture, Forestry and Fisheries of Japan in 2005. Its main characteristics are as follows. Nikomaru is a non-glutinous variety. The culm and panicle lengths are equal to those of Hinohikari, a standard medium maturing variety in Kyushu. Nikomaru has slightly fewer panicles per unit area than Hinohikari. Its lodging resistance is comparable to that of Hinohikari. The shattering property of panicle is classified as hard, and the density of grain is classified as medium. It heads three days later and matures three to five days later than Hinohikari. Its maturity is classified as medium in the Kyushu region, and its viviparity is classified as moderate. Nikomaru is expected to possess Pia and Pii true resistance genes to blast disease. Its field resistance to leaf and panicle blast is equivalent to that of Hinohikari, and it is classified as moderately susceptible. Its yield of brown rice is about 5 to 10% greater than that of Hinohikari. The shape of the grain is comparable, and the size and weight of the grain are slightly greater than those of Hinohikari. Nikomaru exhibits an outstanding grain filling ability and excellent grain appearance under high temperature weather conditions due to lower occurrence of chalky immature grain. The appearance grade of the grain is superior to that of Hinohikari. Its eating quality as boiled rice is equivalent to that of Hinohikari or Koshihikari, the finest varieties of eating quality in Japan. Nikomaru is considered to be adaptable to the plains of the warm and moderate regions of Japan. |

「にこまる」は, 「は系626 (きぬむすめ)」を母とし, 「北陸174号」を父として人工交配を行った雑種の後代から育成された。2002年より「西海250号」の系統名を付し, 関係各府県に配付して地域適応性を検討してきた。2005年に長崎県において奨励品種に採用され, 「水稲農林411号」として命名登録された。稈長は「ヒノヒカリ」と同程度で, 穂数はやや少ない。中稈中間型のうるち種である。出穂期は「ヒノヒカリ」より2～3日, 成熟期は3～5日晩生である。いもち病の真性抵抗性遺伝子型は "Pia, Pii" と推定され, 圃場抵抗性は「ヒノヒカリ」並の "やや弱" である。収量性は「ヒノヒカリ」を5～10%上回る多収である。 |
