  PT19-2 Brassica napus heterogeneity and summary results        
  Standard Proficiency Test | GMO Proficiency Test | Seed Health Proficiency Test
Test round 19-2 B.nap started with the shipment of three samples of Brassica napus seed for purity, other seed determination, germination and viability testing.  

Samples were dispatched in July 2019 and the deadline for reporting test results to the Secretariat was November 1, 2019. The deadline has been extended until November 8, 2019. By this date 93% of the 200 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.
