Great progresses of gene transfer to wheat (Triticum aestivum L. ) have been made since 1992, the birth of the first transgenic wheat in the world, and in pedicular for the recent five years. The system for wheat genetic transformation, represented by particle bombardment has been established, a breakthrough has been made at Agrobacterium-mediated gene transfer to wheat, and the transgenic wheat by Pollen-tube pathways has been ready to commercial production. The main topics of research in the wheat transformation begin to shift from establishment of gene-transferring system to improvement of the wheat by genetic transformation, and this is marked by the success in obtaining transgenic plants with engineering male sterility resistance to diseases and higher quality of flouL These progresses with other major events in the gene transfer to wheat have been reviewed in this papeF, and the problem existed and the prospects have been discussed.
