Primer and SRAP molecular marker garlic variety identification method and DNA extraction device

The invention relates to a garlic variety identification method based on primers and SRAP molecular markers and a DNA extraction device, and relates to the technical field of molecular biology, and 22 pairs of SRAP molecular marker primers can be used for identifying different garlic varieties. The identification method comprises the following five steps: collecting and cultivating garlic resources, extracting DNA, establishing a PCR amplification system, screening core primers, and establishing a fingerprint spectrum. The DNA extraction device comprises an extraction mechanism, an extraction mechanism, a heat preservation mechanism, a drying mechanism, a clamping mechanism, a first box body and a first box cover, the extraction mechanism, the extraction mechanism, the heat preservation mechanism and the drying mechanism are sequentially arranged at the bottom of the first box body, and the clamping mechanism is arranged at the top end of the inner wall of the first box body; and the first box cover is arrang
