Wheat transformation efficiency is closely related to several factors such as receptor genotype, constructed plasmid and selection procedure after bombardment or co-cultivation. In our study, several kinds of antibiotics, which were normally used in plant transformation to the selection genes of nptII, bar and hpt, were tested for the optimal concentrations for wheat transformation. The results showed that 25 - 50mg/L of geneticin (G418) was suitable for the selection of nptII, kanamycin or neomycin was not suitable for use. 3 - In our study, several kinds of antibiotics, which were normally used in plant transformation to the selection genes of nptII, bar and hpt, were tested for the optimal concentrations for wheat transformation.
