概要

• 論文の詳細を見る

• Ninety-nine recombinant inbred lines (RILs) were grown for three years and yield components were evaluated. Composite interval mapping showed that the <I>vrs1 </I>and <I>uzu </I>genes consistently controlled grain weight per plant. The analyses also identified a new QTL of kernel length on chromosome 3H, a QTL for kernel width on chromosome 6H and a QTL for thousand-kernel weight on chromosome 2H. The QTL generated in this study may be a useful target for marker-assisted selection in breeding programs.
