Abstract  Genetically modified Brassica napus NS-B50027-4 is a new variety containing a high proportion of ω3 fatty acids and LC-ω3 fatty acids approved by the Australia-New Zealand Food Standards Agency. So far there is no literature report on the detection method of this new genetically modified B. napus variety. Therefore, it is necessary to establish a qualitative and quantitative detection method for this species. In this study, primers and probes were designed according to the internal reference gene HMG (high mobile group protein) of B. napus and A02 chromosome of transgenic B. napus NS-B50027-4, respectively. The specificity, sensitivity and accuracy of the primers and probes were determined by conventional PCR and qPCR technology to determine the detection limit and quantification limit of the detection method. The experimental results show that the two designed primers could only amplify the target, the detection limit of hmg primer can reach 5 copies/μL, and the detection limit of A02dn2 primer is 1 copy/μL. Therefore, the established qualitative and quantitative detection method of genetically modified B. napus NS-B50027-4 has high specificity and selectivity, excellent sensitivity and accuracy. The research results provide technical support for the qualitative and quantitative detection of genetically modified B. napus NS-B50027-4.
