Standard PT

Rounds and Results

For each PT round, the testing instruction is first released, followed by the heterogeneity result and summary report.

The first comparative test system organised by ISTA with the aim to estimate the technical competence of member laboratories and prepare them for ISTA accreditation. It includes traditional tests that are most common in the seed testing laboratories such as purity, other seed determination, germination, moisture, and viability tests.

PT Rounds

  • PT24-2 Matthiola longipetala Instruction

    Participants of test round PT 24-2 shall receive samples of Matthiola longipetala for germination test, as part of the ISTA Proficiency Test Programme for 2023-2025.

    In case there is any doubt as to the integrity of the samples (e.g. broken seal, inadequate quantity of seeds) the laboratory is requested to contact the ISTA Secretariat.

    Please test samples and report the results in accordance with the current ISTA Rules. Accredited laboratories are required to participate in all tests they hold a valid accreditation for. For non-accredited tests participation is voluntary.

    Seed storage and submitting results: Remaining seed shall be carefully stored, under the responsibility of your laboratory, for re-testing or follow-up corrective actions if required. There should be sufficient seed for one re-test. It is also forbidden to sow the seeds, outside your laboratory, in the fields.

    You are kindly asked to initiate the tests immediately after receipt of the samples and report the results by e-mail to pt@ista.ch.

    Deadline for reporting results: November 1, 2024

    Samples were dispatched in March 2024 and the deadline for reporting test results to the Secretariat was 1 July 2024. By this date 95% of the 213 participants submitted their test results.    

    Heterogeneity test results are provided on the ISTA website to allow the participants to review them. Heterogeneity results are the mean results of 10 samples that had been tested by the Test Leader prior to sample dispatch. The results are not necessarily the means that will be calculated but shall give a first indication of the seed quality parameters.   

    With publishing this heterogeneity test report, no further results are accepted for submission. Laboratories are kindly requested not to provide results of re-tests unless they wish to receive advice from the Secretariat or the Proficiency Test Committee Chair on issues encountered or specific questions arising.

    Samples were dispatched in July 2022 and the deadline for reporting test results to the Secretariat was 1 November 2022. By this date 92% of the 195 participants submitted their test results.

    Heterogeneity test results are provided on the ISTA website to allow the participants to review them.

    NOTE: 2 tubers were added to the Lot 2 sample and identified by many participants as other seed of Cyperus esculentus. According to the current ISTA Rules 3.3, tubers shall be classified as inert matter. This was confirmed by the ISTA Purity Committee and the identification of the Cyperus esculentus is therefore excluded from the OSD test. Reporting of 2 tubers of Cyperus esculentus was expected in the description of inert matter.

    These tubers are in some countries noxious. Therefore the participants may include them in their collection of noxious species. The images of the tubers are provided under the below link.
