| Outline of Final Research Achievements |
We conducted a quantitative trait loci (QTL) analysis to clarify the genetic mechanism of plant type such as epicotyl length and stem twining in adzuki bean. From result of QTL analysis, we detected two QTLs for longer epicotyl length. In addition, the segregation patterns revealed that longer epicotyl length is controlled by recessive genes. Furthermore, it was clarified that there was epistatic effect between two QTLs. We identified a QTL associated with stem twining that was co-located on epicotyl length QTL.

| Academic Significance and Societal Importance of the Research Achievements |
農家戸数の減少と高齢化が進みつつあり、農作物の省力機械化栽培技術の開発に対する期待は非常に大きい。特に、機械収穫適性の低いアズキ では新品種の開発が望まれている。本研究課題は、アズキの機械化栽培適性と大きく関わる発芽後の植物の形態形成および生育後期の草型の遺伝機構を明らかになった。本研究成果は、活用して新品種の開発をとおしてアズキの新しい栽培技術の確立に貢献すると考えられる。
