15 hectares. Gaozhou wild rice is known as the
excellent characters and favorable traits that are worth
mining and utilizing. We are the first research group to
construct an advanced backcross population using
Gaozhou wild rice for genetics and breeding studies in
China.
Although overall agronomic characteristics of wild
rice is inferior to that of the cultivated rice, our results
demonstrated that wild rice alleles had a significant
effect on yield and yield related components in the
