Analysis on the Important Problems of Crop Germplasm Resources Zhejiang Province has abundant crop germplasm resources. After the founding of the country, more than 10,000 kinds of germplasm resources have been investigated. Including rice, vegetables, fruits, edible fungi, tea, silkworm, Chinese herbal medicines, green manure, flowers, beans, barnyardgrass, hemp and other agricultural species. Long-term farming traditions have nurtured and formed regional distribution characteristics with comparative advantages. The establishment of a crop germplasm resource bank has a high value for the preservation of planting resources. At the same time, it also has great significance for the deletion and evolution of crops. There is a certain basis for the collection, protection and utilization of germplasm resources. Early selection of excellent varieties directly from farm breeds and genebanks, or systematic breeding of new varieties, later used as parental materials to cross breed new varieties and other means, breeding promoted a large number of new varieties, and promoted the sustainable and healthy development of agricultural production. . However, there are certain difficulties in the establishment of the crop Germplasm Bank. Below we mainly analyze the main problems. 1. Not enough understanding of the importance of germplasm resources: especially the municipal and county-level agricultural administrative departments have not paid enough attention to the protection of germplasm resources, and some have little knowledge of the resource conditions in the region, let alone effective. Protection and utilization. 2. The lack of germplasm resources sharing mechanism is based on the collection of germplasm resources that are mainly collected by scientific research units as the “private resources†for new breeding varieties. The lack of information sharing and collection systemicity makes it impossible to collect germplasm resources on the one hand. Complete, on the one hand, some of the same germplasm resources are repeatedly stored in different units. 3. Insufficient investment in protection of germplasm resources: Protection work lacks research on human resources, infrastructure, and technology routes. The "Administrative Measures on Crop Germplasm Resources" of the Ministry of Agriculture stipulates that the work of crop germplasm resources is a public welfare undertaking, and it is necessary to guarantee the stability of work and sources of funding. At present, there is no special and stable investment in Zhejiang Province. Scientific research units use germplasm resources such as refrigerators and other simple methods to preserve germplasm resources. The number of conserved germplasm resources is limited, the time is short, and they are easily lost.
