Abstract: In this research the killing curve of mannose was tested at the subculture,differentiation and rooting stages of sugarcane cultivar ROC22. Then the expression cassette containing a pmi selection marker gene and a GFP report gene was transformed into sugarcane embryonic callus by Agrobacterium-mediated method. Resistant plants were obtained after selection by Mannose. The PCR detection result and GFP microscope observation result both show that our lab had established a high efficiency PMI/Mannose selection system in sugarcane transformation.

Key words: sugarcane transgenic, mannose, pmi gene, GFP gene
