Abstract:

China is one of the most abundant countries in the world in terms of livestock and poultry germplasm resources. The protection and utilization of the germplasm resources are of great significance for breeding new varieties of livestock and poultry, promoting the sustainable development of China's animal production and ensuring the effective supply of animal products. However, the current insufficient development and utilization of livestock and poultry germplasm resources have seriously affected the security of livestock products in China. Therefore, it is one of the key strategies to ensure the security of national livestock products in the long term in China to comprehensively collect and reserve livestock and poultry variety resources, especially digital sorting of germplasm resource characteristics, data sharing of germplasm resources, and consequently, promoting physical sharing of germplasm. In this study, the species and spatial distribution of the existing domestic animal variety resources and germplasm resources, the characteristic data of various traits divided by characteristic types, the appearance characteristics of different varieties and sexes, pictures and videos in specific habitats, as well as the gene map of some germplasm were digitally categorized. The system provides visual query and full-text retrieval of various types of data in the above, as well as the query and statistical analysis of spatial distribution and attributes of variety resources based on GIS technology. Therefore, it provides a convenient platform and analysis tool for the query and sharing of existing germplasm resource data. This study also points out that the future development direction of the platform is to carry out statistical analysis of germplasm resource character data on the basis of further expanding the evaluation data of germplasm resources, make early warning and prediction for the rescue protection of rare and endangered germplasm resources, and finally safeguard China's livestock and poultry germplasm resources, especially the core germplasm resources serving the animal industry.
