Objective To improve the testing ability and experience of laboratory for genetically modified ingredients in major crops, and be ready for the supervision and testing of major crops. Methods According to the organizer’s proficiency testing operation instructions and announcements of the Ministry of Agriculture, 20 samples of four major crops including Zea mays, Glycine max, Oryza sativa, Brassica napus were tested for genetically modified ingredients. Results The proficiency testing of CaMV 35S promoter, NOS terminator and corresponding internal standard genes of all the 20 samples had been satisfactorily evaluated. Conclusion The laboratory has obtained same results through ordinary PCR and real-time fluorescent PCR, which proves that the laboratory has mastered the relevant testing standards and methods, and has the ability to detect genetically modified components in major crops.
