A Database for Triticeae and Avena
The European Barley Database (EBDB) of the European Cooperative
Programme for the Conservation and Exchange of Crop Genetic Resources
(ECP/GR) has been maintained at the Zentralinstitut für Genetik und
Kulturpflanzenforschung (ZIGuK) of the Academy of Sciences of the German
Democratic Republic at Gatersleben since 1985. The third meeting of the
ECP/GR Barley Working Group (Gatersleben, 18-20 April 1989) recommended
to widely publicize information about the EBDB among barley breeders and
The EBDB has the following objectives: (1) to catalogue the barley
germplasm in European genebanks; (2) to provide information on the barley
germplasm on request; (3) to facilitate the identifaction of duplicates in
order to rationalize the maintenance and evaluation of the material in
genebanks; (4) to identify geographical gaps in European collections as
a basis for further collecting strategies.
Present state of the EBDB
The EBDB is maintained under the database management system dBASE
II. It contains passport data of 55,369 accessions from 35 barley
collections in 26 countries, the largest collections being Gatersleben
(10,266 accessions), Cambridge, U.K. (9,458), Braunschweig, F.R.G.
(8,274), Addis Ababa, Ethiopia (5,335), and Wageningen, Netherlands
(2,912). In addition, information on 5142 barley cultivars and lines
extracted from Arias et al. (1983) is incorporated for reference. Data
on the following descriptors are stored in the EBDG: EBL Number (unique
identifier in the EBDB), Genebank, Accession Number, Donor, Donor's
Number, Seasonality, Row Number, Country of Origin, Accession Name,
Breeder, Other Numbers, Species, Subspecies, Convarietas, Varietas,
Subvarietas, Expedition/Collector, Collector's Number, Province, Site,
Latitude, Longitude, Altitude. Data on Country of Origin, Genebank,
Donor, Breeder, and Expedition/Collector are stored as codes or
The European Barley List (EBL) (Knupffer, 1987) presents the barley
germplasm in three parts:
Part 1 (23,418 accessions): cultivars, lines and special resources
of Hordeum vulgare L., sorted alphabetically by accession name.
Part 2 (29,166 accessions): collected (primitive) material and
unnamed accessions of H. vulgare,, sorted by country of origin and
geographical information (province/site).
Part 3 (2,785 accessions): wild species of Hordeum, sorted by
scientific name, country of origin and geographical information.
A survey of the provenance and botanical composition of the
material documented in the EBDB is given in Knupffer (1988).
Access to information from the EBDB
Information from the EBDB is open to genebanks, breeders, and
scientists free of charge. The complete contents of the database is
available on magnetic media (preferably diskettes) and in printed form
(European Barley List, some copies available from IBPGR: Mr. P.M.
Perret, IBPGR, Via delle Terme di Caracalla, I-00100 Rome, Italy).
Searches in the database will be conducted on request; the resulting
data are provided as printouts or on diskettes. Common types of
inquiries are "Print a list of all two-rowed winter barleys originating
from the Far East" or "From where could I obtain living seeds of the
cultivars and strains listed below?"
If data are requested on diskettes, an appropriate number of empty
diskettes should be sent to the EBDB in advance. Data are available on
5.25" MS-DOS diskettes (360 or 720 kBytes) in ASCII fixed format files
or as dBASE III files. The complete database occupies approximately 20
MBytes. Please contact the author of this note for more details and the
required number of diskettes.
Future development of the database
As soon as appropriate hardware becomes available, the database
will be transferred from dBASE II to dBASE III. The following
activities will be undertaken:
More detailed information on the EBDB is presented in the Reports of
the Barley Working Group meetings (1983, 1986, 1989) and of a Barley
Workshop (1985), which are available from the IBPGR, and in Knupffer et
al. (1987), Knupffer (1988, 1989).
