In situ on farm conservation of maize

Bucovina, Maramures and Apuseni Mountains are considered as last refuges of the Romanian traditional agriculture

Ex situ conservation of maize genetic resources in

Suceava Genebank

Mandate:

exploration, inventorying, collecting and

studying of plant genetic resources in

order to appropriately conserve them, as

a precondition for food security, poverty

eradication and environmental protection.

Structure of maize collection

- Number of collected or received

accessions: 5391 (40%)

- Biological status:

- local landraces – 3591 acc.

- inbred lines – 1955 acc.

- synthetics – 113 acc.

- obsolete cultivars – 32 acc.

- Origin of accessions:

- Romania - 5034 acc. (88%)

- Other countries - 657 acc. (12%)

Maintenance of maize seed samples in Suceava Genebank

Active collection at a temperature of + 40C 5108 accessions

Base collection at a temperature of - 200C 2094 accessions

CONSTRAINTS TO

EFFICIENT CONSERVATION

No support for locale people who maintain in small farmers the

maize landraces.

Lack of financial resources and technical staff for multiplication and

regeneration of more maize accessions .

Lack of financial resources for secondary evaluation of all maize

accessions preserved in Suceava Genebank

No On - line accessibility for agricultural research institutions to

update information from the national database;

No safety duplication in other similar institutions.
