Achievements made in past decade in cotton genetic engineer ing were described in this paper.Transgenic cotton with single Bt gene of double Bt+CpTI genes were generated.The registered varieties of Bt cotton have been widely ado pted by farmers and total acreage of Bt cotton was approximately 120,000 hectare s in 1999.Meanwhile,a series of related techniques,including the genetics,cultiv ation and propagation of selected lines,the bioassay of insecticidal activities. the detection of Bt protein espression in transgenic plants,the resistance of co tton bollworm to Bt protein,the integrated pest management in cotton fields,and the biosafety assessment of Bt cotton etc,were developed that could be practical ly used in commercial production.In addition,the progrss in genetic engineering of cotton with resistance to fungal diseases and better fiber quality was also r eviewed.
