  Standard Proficiency Test | GMO Proficiency Test | Seed Health Proficiency Test
Test round 20-3 F.sp started with the shipment of three samples of Felicia sp. for germination testing.

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, 90% of the 113 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.
