Research Abstract

In order to investigate important loci for rice domestication, QTL analysis of domestication-related traits was carried out with four backcross recombinant inbred populations derived from the reciprocal crosses between two rice cultivars (Japonica and Indica types) and an Asian wild rice accession. The results suggest that QTLs, commonly detected in the two populations having cultivated or wild genetic backgrounds, may have played important roles in the early phase of rice domestication.
