Mediterranean Germplasm Database (MGD)

The Mediterranean Germplasm Database (MGD) is the digital twin of the agri-food plant seed collection (Mediterranean Germplasm Genebank - MGG) maintained at the Institute of Biosciences and BioResources (IBBR) of the Italian National Research Council (CNR) in Bari, Italy. Overall, the collection preserves more than 59,000 accessions of 870 species from 203 genera and 39 families (mainly Poaceae, Fabaceae, Solanaceae, Brassicaceae, Asteraceae, etc.). Over 13,000 samples have been directly collected through time and georeferenced by IBBR exploration teams, while others have been acquired from other Institutions through exchange activities. The main objective of MGG is the preservation of genetic resources of herbaceous plants of interest for the Mediterranean agriculture. Particular attention is dedicated to specific segments of plant genetic resources, such as local varieties (including "typical products") or endangered agro-ecotypes, wild relatives of crops and plants potentially useful for the extraction of bioactive or biotechnological compounds. The main commitments of MGG since 1970 are: (i) the collection, conservation and distribution of PGR; (ii) the characterization and evaluation of PGRs and the analysis of their genetic structure; (ii) the selection and pre-breeding of PGR, and the recognition of useful genes.

地中海种质数据库（MGD）系意大利国家研究委员会（CNR）巴里生物科学与生物资源研究所（IBBR）所维护的农业植物种子收集库（地中海种质基因库 - MGG）的数字化孪生。总体而言，该收集库保存了来自203个属、39个科（主要包括禾本科、豆科、茄科、十字花科、菊科等）的870个物种的超过59,000份遗传资源。超过13,000个样本已由IBBR的探险队直接采集并进行了地理参考，其余样本则通过交换活动从其他机构获得。MGG的主要目标是保护对地中海农业具有兴趣的草本植物的遗传资源。特别关注植物遗传资源的特定领域，例如地方品种（包括“典型产品”）或濒危农业生态型，以及作物和植物的野生近缘种，这些可能对提取生物活性或生物技术化合物具有潜在用途。自1970年以来，MGG的主要承诺包括：（i）遗传资源的收集、保存和分发；（ii）遗传资源的特征描述与评估及其遗传结构的分析；（iii）遗传资源的选育和预育种，以及有用基因的识别。
