Test round 17-1 F.aru started with the shipment of three samples of Festuca arundinacea seed for purity, other seed determination and germination testing.
The F.aru mixture for seed identification were are also shipped to the participants at that time.

Dispatch date was July 24, 2017 and the deadline for reporting test results to the Secretariat was November 1, 2017. The deadline was extended to December 1, 2017.
By this date 92% of the 152 participants had submitted their test results.Heterogeneity test results are provided on the ISTA web site 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.

The list of other seeds added in the seed mixture (voluntary participation for all laboratories) is also published.
The photos of the seeds from the seed mixture will be published later.

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.
