The invention relates to the virus detection technologies in the fields of molecular biology and molecular virology, and in particular relates to a reverse transcription fluorogenic quantitative PCR primer for rapidly identifying a high virulent Newcastle disease virus (NDV) strain and a method for identifying the high virulent NDV strain by adopting the PCR primer. The method comprises the following steps: extracting RNA of a to-be-identified virulent strain, carrying out RT-qPCR amplification, and identifying that the to-be-identified virus is the high virulent NDV strain when viral nucleic acid is successfully amplified; and identifying that the to-be-identified virus is not the high virulent NDV strain when the viral nucleic acid is not successfully amplified. According to the identification method, only once RT-qPCR amplification is needed, whether the to-be-identified virus is the high virulent NDV strain or not can be judged, and the detection method is simple, convenient and flexible, and is easy to operate; the detected minimum concentration of RNA is 1 copy/mu L, and the detection sensitivity is high; the design primer only can amplify the high virulent NDV strain, and can not amplify low virulent strains and other virulent strains, and therefore, the specificity is strong.
