This invention provides a method for storing mango seeds, belonging to the field of seed preservation technology. The method involves cutting off mango fruits with embryos, along with their pedicels and branches, 77-84 days after fruit set. A mixture of pyraclostrobin, lambda-cyhalothrin, and chlorothalonil is sprayed on the fruit, pedicels, and branches. After drying, styrene-butadiene latex is applied to the pedicels and branches. Once the latex dries, a mixture of guanidine-copper acetate and benzoyl-pyraclostrobin is sprayed on the fruit, pedicels, and branches again. After drying, the mango fruits with petioles and branches are placed in a sealed box and stored at 10-14°C. The mango variety used is the Golden Phoenix mango. This invention increases the storage period of Golden Phoenix mango seeds from 1.5 months to 5 months, which is of great significance for the genomics and cell biology research of Golden Phoenix mangoes.
