"Botansoba" and an F_1 plant that was produced by crossing "Botansoba" and F. homotropicum from Yunnan, China. "Botansoba" is a summer ecotype that is photoperiod-insensitive with a short growth period, and F. homotropicum is a wild relative of common buckwheat. The flower of "Buckwheat Norin-PL1" is a long-homostyle, in which the lengths of styles and stamens are almost the same. Self-compatibility or incompatibility can be identified by the flower morphology. Because "Buckwheat Norin-PL1" does not possess an allele of brittle pedicels derived from F. homotropicum, the progeny produced using "Buckwheat Norin-PL1" do not exhibit brittle pedicels. The seed size of "Buckwheat Norin-PL1" is similar to that of "Botansoba". "Buckwheat Norin-PL1" does not grow so vigorously, but it is very useful as a parental line for producing self-compatible buckwheat., 「そば中間母本農1号」は夏型品種の「牡丹そば」に普通ソバの近縁自殖性野生種 Fagopyrum homotropicum を交配し, その後「牡丹そば」を戻し交配して選抜育成された自殖性の普通ソバである。「そば中間母本農1号」の花はおしべとめしべの長さがほぼ等しい花形をしており, この花形から自殖性が識別でぎる。「そば中間母本農1号」は F. homotropicum 由来の子実脱落性対立遺伝子を除去してあるため, 普通ソバと交配した後代でも子実が脱落することはない。「そば中間母本農1号」の種子の大きさは「牡丹そば」並みである。生育は旺盛でないが, 自殖性の育種素材として利用できる。}, pages = {11--17}, title = {自殖性の普通ソバ「そば中間母本農1号」の育成とその特性}, volume = {49}, year = {2008}, yomi = {マツイ, カツヒロ and テツカ, タカヒサ and ハラ, タカヒロ and モリシタ, トシカズ} }
