This invention relates to a method for rapidly screening filamentous fungi that produce high levels of triglycerides and polyunsaturated fatty acids, belonging to the field of microbial technology. The method employs a two-stage screening strategy of "resistance primary screening – fluorescence secondary screening." In the primary screening stage, strains with strong lipid synthesis capabilities are initially screened by adding a combination of phytocyanin and quizalofop-p-ethyl inhibitors to the culture medium. In the secondary screening stage, cellophane culture technology and Nile red fluorescence staining are combined to quantitatively assess the triglyceride content of the colonies, achieving rapid and non-destructive screening. This method is simple to operate, highly efficient, and shows a significant positive correlation between fluorescence intensity and triglyceride content. It is suitable for mutagenesis breeding and industrial strain selection of oil-producing filamentous fungi such as *Morchella alpineensis*.
