The invention discloses a specific amplification primer and a fluorescent probe for detecting the resistance mutation of influenza A H1N1 viruses, application thereof, and a method for detecting the resistance mutation of the influenza A H1N1 viruses. When the method of the invention is in use, an operation process is simple and a result is visual and clear; the primer and the probe have high sensitivity and high specificity; whether the influenza flu is a resistant mutant can be identified in the influenza detection and monitoring quickly; and thus, labor and material consumption is greatly reduced.
