DNA Proficiency Test

2nd ISTA DNA Proficiency Test on Wheat (Triticum aestivum subsp. aestivum)

The aim of the proficiency test is to check the ability of individual laboratories for obtaining DNA profiles for wheat using the marker set in the Rules. These DNA profiles will be compared against a Reference Matrix using two parameters, the number of varieties wrongly rated and the number of markers with wrong results.

PT2 is aimed to test laboratory performance and is mandatory for ISTA accredited laboratories performing DNA tests on wheat and having this test in the accreditation scope. This PT is also open for not accredited laboratories willing to test their performance.

The registration fee for the participation is charged in Swiss Francs (CHF) and must be paid prior to submission of the samples to the laboratory. At the moment the registration fee for non-members of ISTA is CHF 1000. The fee covers the costs for seed material, sample preparation, packaging and shipment. ISTA Member Laboratories do not have to pay a participation fee as this service is covered in their yearly membership fee. They must identify themselves on the registration form by referring to their ISTA member code.

Laboratories interested in participating should please send a completed registration form to the ISTA Secretariat nadine.ettel@ista.ch before November 30, 2026.
