The importance of the construction of core collection of castor As a special crop in China, the use of ramie has been continuously expanded. The versatile uses of ramie, such as medicinal value, feed use, soil and water conservation, industrial raw materials, and bio-energy, have begun to attract attention. For example, the Ministry of Water Resources has established ramie as a soil and water conservation crop in the hilly region of the South; ramie leaf has entered the pilot stage as animal feed; the medicinal value of ramie leaf extract has obtained important results. For the genetic improvement and gene mapping of these new uses of castor, the role of germplasm resources as the basis for scientific research is indispensable. However, the amount of ramie germplasm is large, and the screening work for specific purposes is large. The core germplasm can represent the genetic diversity of the entire germplasm resource and can improve the identification efficiency. For example, Holbrook identified the leaf spot resistance of peanut core collections and doubled the efficiency compared to using all germplasm identification. After Jiang Huifang and others established the core germplasm of peanut, they analyzed the resistance to infection and production of Aspergillus flavus. Eight samples of the infection and 8 toxin-producing germplasms against Aspergillus flavus were identified and analyzed. Than to improve efficiency. Therefore, the construction of ramie core germplasm can lay a solid foundation for the new use of ramie. From the above, it can be seen that the establishment of a germplasm resource bank has great effects on various practical uses of crops and can provide a wider range of species. In addition, it also provides more possibilities for survival of the fittest. The crop Germplasm Bank just meets these needs. The germplasm resource bank of crops is designed to excavate and collect seeds of various crop varieties and scientifically store them so that the germplasm still has original genetic characteristics and high germination power after more than ten years or even decades. For breed improvement, it is of great significance to cultivate new varieties with high yield, good quality, and strong resistance, and to provide rich germplasm and research materials for biological theoretical research. The seed storage is the most frequently used equipment and is divided into long-term storage, medium-term storage and short-term storage.
