Seed Conservation Unit

Seed Conservation unit/Gene bank

Seed conservation unit (Gene bank) is a vital unit of the PGRC. The main activities of the unit are processing seed materials and storage for conservation, maintenance and monitoring viability and distribution of conserved gremplasm. Currently, two types of collections are held at seed conservation unit.

  1. Active Collection: - active collection is stored for short to medium term. The collection generally held at temperature 5 C0 and Relative humidity (R/H) 25% -30%.Samples/Accessions consist in active collection are used for regeneration ,evaluation, research and distribution purposes.
  2. Base Collection: - Base collection is stored under conditions which retain viability for long periods of time .the collection is held at temperature 1 C0 and Relative humidity (R/H) 25% -30%. Samples/Accessions in base collection do not use for distribution or research purposes, but only use to regenerate and viability monitoring when necessary.

The unit has 16 storage modules /cooling room to store the seed collection. Currently seed conservation unit has conserved approximately 14,406 accessions of plant genetic resources of about 16 crop groups.

The present conservation status of the gene bank(up to 31st December 2017)
