Mediterranean Germplasm Genebank - Hordeum dataset (ITA436-MGG-Hordeum)

Citation

Description

The dataset contains about 2000 accessions of several species of Hordeum (barley) from the Mediterranean Germplasm seed bank in Bari (Italy). Seeds have been collected by the personnel of CNR-IBBR throughout the Mediterranean Basin (Spain, Italy, Greece, Cyprus, Morocco, Algeria, Tunisia, Egypt, etc.), middle East (Syria, Yemen, Iraq, Iran, etc.), and Eastern Africa (Ethiopia), but also provenances from Asia (India, Nepal, etc.) are included. Seeds are maintained in sealed cans at -20 °C (long-term storage) and paper bags at 4 °C (short-term storage), and periodically checked for germination and refreshed. Seed lots are available upon request at https://ibbr.cnr.it/mgd/ or by contacting mgd.staff@ibbr.cnr.it.

Purpose

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 collected over time and georeferenced by IBBR exploration teams, while others have been acquired from other Institutions through exchange activities.

The main objective of MGG is to preserve the genetic resources of herbaceous plants of interest for Mediterranean agriculture. Particular attention is dedicated to specific segments of plant genetic resources, such as local varieties (including "typical products") or endangered agroecotypes, wild relatives of crops, and plants potentially useful for extracting 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.

The seed bank is endowed with refrigerated rooms at 4 °C, 0 °C, and -20 °C, where more than 14,700 kg of seeds are currently stored.
