  Standard Proficiency Test | GMO Proficiency Test | Seed Health Proficiency Test
Test round 17-1 B.nap V started with the shipment of three samples of Brassica napus seed for radicle emergence testing.
Dispatch date was April 1, 2017 and the deadline for reporting test results to the Secretariat was July 1, 2017.
The deadline was extended to August 10, 2017. By this date 80% of the 71 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 the 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.
