Abstract: A great progress has been made in the research and development of plant genetic engineering in China since last decade. Diverse methods and systems for gene transfer into plants have been developed and optimized, and the research emphasis has been shifted from establishment of the genetic transformation system to introduction of genes responsible for new economic and/or agronomic trails into targeted plants. More than 145 genes, single or combined, have been transferred into no less than 90 crop species including rice, wheat, maize, rape, soybean, cotton, etc., and expressed in the transgenic plants. More than 90% of the genes used were of economic and/or agronomic importance and distributed in nine major sections: pest-resistance, disease56-resistance, stress-resistance or tolerance, herbicide-resistance, quality and productivity improvement, artificial male sterility, factory plant (bio-reactor), environment protection and GMO safety. Up to now, 10 species of transgenic crops have been released to environment testing and 4 to commercial production. The total commercially cultivated area of transgenic crops reaches 1 500 000 ha/year, which takes the 5th position in the world. Based on these progresses, prospective achievements for next five years in the research and development of plant genetic engineering are discussed.
