【Abstract】 Utilizing the DGWG extensively as a source of semidwarfism in the production of rice may causes genetic vulnerability. It is great significant to broaden the genetic base and create new useful semidwarf germplasm. Some problems in current rice semidwarf breeding and the significunce of induced additional semidwarf source were analyse as well in the present paper.更多还原
