          <datacite:description descriptionType="Abstract">The Tohoku Agricultural Research Center of Japan's National Agriculture and Food Research Organization (NARO) has released a new buckwheat cultivar 'Nijiyutaka'. 'Nijiyutaka' was derived from a line selected from the progeny of a cross between 'Kuzuu-zairai' and 'Togakushizairai'. 'Nijiyutaka' has the following major agronomic characteristics : high to very high lodging resistance, black hull color, and large seed size. 'Nijiyutaka' also matures a few days later than 'Hashikami-wase' and at the same time as 'Iwate-wase' in the Morioka area of Iwate prefecture, in northern Honshu. Plant height is about 10cm more and seed yield is a little higher than in 'Hashikami-wase'. The thousand-grain weight is about 36g, and 1 L of seeds weighs about 630g. In processing tests by three flour milling companies, 'Nijiyutaka' was judged to be more suitable than 'Hashikami-wase' for making buckwheat flour and noodles. 'Nijiyutaka' appears to be most suitable for the Tohoku region and southern Japan, and can be sown in summer for harvesting in autumn.</datacite:description>
          <datacite:description descriptionType="Abstract">「にじゆたか」は耐倒伏性が '強～極強' で東北地域で栽培されている既存品種に比べ倒れにくく、大粒で子実外観に優れるソバ新品種である。2001年度に「葛生在来」と「戸隠在来 (秋) 」を交配し、雑種第2世代で個体選抜を行った後、系統選抜により育成された。主に東北地域以南の夏播き栽培に適する。育成地 (岩手県盛岡市) における本品種の成熟期は「階上早生」より数日遅く「岩手早生」並の 'やや早' で、草丈は「階上早生」より10cm程度長く、収量は「階上早生」をやや上回る。子実は黒く千粒重は約36g、容積重は約630gである。実需試験により、加工適性や食味について「階上早生」より 'やや優る' との総合評価を得ている。2011年に秋田県、岩手県、宮城県で栽培に着手したほか、2012年以降は東北各地をはじめ関東・中部地方においても栽培予定となっており、今後広範囲に普及することが期待される。</datacite:description>
