EUROPEAN PISUM DATABASE

Through the support of IBPGR the first steps have been taken to establish a European Pisum database. To date, passport data from 18 collections have been obtained and collated. Selected descriptors have been used to prepare a common catalogue of Pisum accessions. Currently this catalogue contains 22,850 entries. It includes data of the World Base Collection for Pisum (Nordic Gene Bank, Alnarp).

A set of nine descriptors has been used for the identification of accessions in the catalogue:

1.

Country............

country where collection is maintained.

2.

Institute..........

institute where collection is maintained.

3.

 

 

Accession..........

 

 

institute collection number and identifying prefix e.g. WBH, WL, VIR, PI, JII, PIS, BO, CGN etc.

4.

 

Name...............

 

species, sub-species, convar, variety names, etc.

5.

 

 

Synonyms...........

 

 

includes collection prefixes, numbers, donors codes, and true synonyms where known.

6.

 

Origin.............

 

country from which accessions were obtained, not collected.

7.

Donor..............

name, and institute.

8.

 

 

Donor Number.......

 

 

will often be an institute collection number with prefix e.g, WL, WBH, PI etc.; may be equivalent to synonyms.

9.

 

Country Origin.....

Preliminary observations indicate that considerable duplication occurs both within and between collections.
