Plant seed origin is the most basic material for variety improvement, and the polymorphism and genetic variation of seed origin are the driving force behind the continuous progress of crop breeding. In recent years, as agricultural operations are moving towards a specialized economic production model, crop cultivation is mostly based on a generation of hybrid seeds or fixed commercial varieties, causing wild or local species to be neglected and disappearing day by day. However, these wild species are often resistant to pests and diseases. Genes such as tolerance to stress (such as tolerance to high, low temperature or drought) are precious materials for human beings to respond to changes in the cultivation environment or special goals in the future. In view of the need for sustainable agricultural development, countries around the world have established crop seed banks to preserve a large number of plant genetic substrates and continue the divergence of crop genetics. The preserved seeds can be used for breeding improvement, technology and other academic research; on the other hand, they can be fed back and restored in the natural biological ecology to maintain ecological balance.
