  PT17-2 Trifolium repens heterogeneity and summary results        
  Standard Proficiency Test | GMO Proficiency Test | Seed Health Proficiency Test
Test round 17-2 T.rep started with the shipment of three samples of Trifolium repens seed for purity, other seed determination, moisture and germination testing.

Dispatch date was July 27, 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 93% of the 162 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.

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.
