For how many years in the past has the Turkish government enforced this? The reason I ask is that many of the Turkish entries in the ARS-GRIN database say something like, "growing near Yayladag." Since each accession is dated, then the varietal purity might be implied by the government regulation, if it was in force at that time.
This would be more meaningful than a statement like, "growing near Danville, Virginia," where many varieties have been grown.

This seed regulation finished in 2002, after 2002 according to the contract farming system, company (which signs the contract with the farmer) have to provide seeds to the farmer. This is a very painful process because of the bureaucratic procedures like import permits (if it's a foreign variety), tobacco trade permits and other permits from ministry of agriculture, etc. Also the company have to certificate the purity of the seeds and the plants otherwise the crop will not be eligible for a trade (both domestic and foreign market). What ever it is, this is not our case.
But the seeds which were donated from Turkey to ARS-GRIN are not directly related with this agricultural policy (for some). Why ? Because some of them are donated by research institutes. For example, there're three Bitlis seeds in ARS-GRIN which were donated from Turkey. One of them was donated by Aegean Regional Agricultural Res. Inst. (this is the old name of the institute, new name is Aegean Agricultural Res. Inst.) and other one was donated from Plant Genetic Resources Res. Inst.. (third Bitlis seed explanation is below). Seeds were not donated for favor, these institutes have some cooperations directly with ARS-GRIN or with other institutes in the US for some scientific studies. So these seeds have to be pure according to science ethics.
But for Yayladağ (PI 481856) (and some others like there's an other Bitlis (PI 481859) there (third one)) it's written in the related ARS-GRIN page, "
Accession was collected. Turkey.". This means there was a collection without a permit or cooperation. These seeds like Yayladağ or Bitlis were probably collected directly from a farm so it should be open pollinated so I have some doubts about these seeds' purity. Although different growing areas are set for specific varieties, this won't be enough for calling them pure seeds, this why government used to give seeds to farmers here.
EDIT: I requested Yayladağ from FTT seedbank and leverhead sent me some Bitlis seeds (they didn't arrived yet). I also have my own Yayladağ and Bitlis (old) seeds. So I'll probably have a chance to compare them this year and you'll all know the comparisons about them app in 6-7 months.
EDIT 2 : I just saw the expression for Yayladağ (PI 481856) in the related ARS-GRIN page. "
Idtype : UNVERIFIED" but there's same expression for some seeds donated from the Turkish Institutes (for example Bitlis (PI 494149). Interesting stuff ...
