  PT18-2 Daucus carota heterogeneity and summary results        
  Standard Proficiency Test | GMO Proficiency Test | Seed Health Proficiency Test
 
Test round 18-2 D.car started with the shipment of three samples of Daucus carota seed for purity, other seed determination and germination testing.  
Dispatch date was July 20, 2018 and the deadline for reporting test results to the Secretariat was November 1, 2018. The deadline was extended to November 25, 2018. By this date 97% of the 170 participants had submitted their test results.   

Heterogeneity test results are provided below, 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.
