Test round 20-3 F.pra started with the shipment of three samples of Festuca pratensis for purity, determination of other seeds, and germination testing. Completion of an ISTA Orange Certificate has also been requested. Participants will soon receive their provisional results by e-mail.

Samples were dispatched in November 2020 and the deadline for reporting test results to the Secretariat was 1 March 2021. This deadline was extended until 15 March 2021. By this date, 94% of the 164 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 Leader on issues encountered or specific questions arising.
