The genus Vitis is one of the most important fruit tree groups worldwide and is widely used for table grapes, winemaking, raisin production, and various processed products, playing a significant role in agricultural production, the food industry, and economic development. Grape germplasm resources are abundant, with numerous cultivated varieties, complex genetic backgrounds, and diverse important agronomic traits, including fruit quality, stress resistance, ripening time, and storability and transportability. These resources provide essential materials for genetic improvement, molecular breeding, and germplasm innovation.

China is one of the important regions for the origin, cultivation, and utilization of grapes, with a long history of accumulating rich grape germplasm resources and achieving remarkable progress in variety breeding, cultivation, and basic research. With the rapid development of genomics, transcriptomics, metabolomics, and phenomics, the systematic integration of grape germplasm information with multidimensional biological data has become an important approach for elucidating the mechanisms underlying key traits, identifying functional genes, and supporting precision breeding.

Based on the conservation, evaluation, and utilization of grape germplasm resources, this database integrates germplasm information, phenotypic data, genomic data, transcriptomic data, metabolomic data, and related functional annotation information. It is dedicated to building a comprehensive data platform for grape genetics, biology, and breeding research. This database will provide strong data support and research tools for the identification of genes controlling important traits, the dissection of molecular mechanisms, the creation of elite germplasm, and industrial applications in grapevine.
