| Research Abstract |
We examined main factors for achieving a high yield in a new type of high-yielding and large-grain rice cultivar, Akita 63. The field experiments showed that a large grain size without reducing the grain number in Akita63 directly leads to high yield, although the grain number largely declines in a mother cultivar, Oochikara. We have identified gs3 as a QTL for grain length in Akita-63, and we are determining a QTL for reducing the grain number in Oochikara.
