Centralised test centres

Centralised Test Centres (CTCs) are officially authorised by us to conduct comparative growing trials for applicants.

An updated list of CTCs is published in each issue of the Plant Varieties Journal.

Benefits of using a CTC

The use of CTCs provides the advantages of testing a larger number of candidate varieties (with a larger number of comparators) in a single comprehensive trial. There is an increase in scientific rigour as well as overall cost savings.

When five or more candidate varieties of the same genus are tested simultaneously, each will qualify for the CTC examination fee, which is nearly 40 per cent less than the normal fee. Trials containing less than five candidate varieties don't qualify for CTC reduction of examination fees.

Becoming authorised as a CTC

Establishments wishing to be authorised as a CTC may apply in writing to us outlining their claims against the selection criteria. There is no cost for authorisation as a CTC.

Initially, only one CTC is authorised for each genus. Exemptions to this rule can be claimed due to special circumstances, industry needs and quarantine regulations. Authorisations are reviewed periodically.

Conditions and selection criteria to become an authorised CTC

To be authorised as a CTC, the following conditions and criteria need to be met:

Appropriate facilities - All establishments must have facilities that allow the conduct and completion of moderate to large-scale scientific experiments without undue environmental influences. A range of complementary testing and propagation facilities (e.g. outdoor, glasshouse, shadehouse, tissue culture stations) is desirable.

Experienced staff - Adequately trained staff and access to appropriately accredited qualified persons, with a history of successful PBR applications, will need to be available for all stages of the trial from planting to the presentation of the analysed data.

Substantial industry support - The establishment will be recognised by a state or national industry society or association, or a written commitment to use the facility from major nurseries or other applicants with a history of regularly making applications for PBR in Australia.

Capability for long-term storage of genetic material - Depending upon the genus, a CTC must be in a position to make a long-term commitment to collect and maintain, at minimal cost, genetic resources of vegetatively propagated species as a source of comparative varieties.

Contract testing for third parties - Unless exempted in writing by us, operators of a CTC must be prepared to test varieties submitted by third parties.

One trial at a time - Unless exempted in writing by us, all candidates and comparators should be tested in a single trial.
