  PT16-1 H.ann heterogeneity results        
  Standard Proficiency Test | GMO Proficiency Test | Seed Health Proficiency Test
Test round 16-1 H.ann started with the shipment of three samples of Helianthus annuus seed: purity, other seed determination and germination testing. 
Dispatch date was February 8, 2016 and the deadline for reporting test results to the Secretariat was My 1, 2016. The deadline was extended to May 15, 2016.
By this date 92% of the 177 participants had submitted their test results.    
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.
