Nice find Mexcurandero!
Who sold these? The farmer himself?

........ To: Etienne de Meijer and the IHA
Let me compliment you on your thorough discussion of breeding genealogies in the December issue of the Journal of the International Hemp Association. You drew your discussion of Lyster Dewey's breeding from the 1927 piece, which means you did not mention the last cultivar which was his crowning accomplishment, ‘Chinamington’. Writing retrospectively after his retirement in 1935 (his program was terminated in '33), Dewey wrote of Chinamington: "The hemp breeding work, carried on by the Bureau for more than 20 years, was discontinued in 1933, but practical results are still evident in commercial fields. A hemp grower in Kentucky reported a yield of 1,750 pounds per acre of clean, dew-retted fiber from 100 acres of the pedigreed variety ‘Chinamington’ grown in 1934. This is more than twice the average yield obtained from ordinary unselected hemp seed."
I was told by Dr. Bocsa of the GATE Research Institute at Kompolt in Hungary, that Dewey sent Chinamington to Fleischmann (the founder and director of the GATE Institute from 1918 to 1951) and that it was used as one side of the first hemp hybrid, the other side was Kompolti. Dr. Bocsa said that Chinamington was later than Kompolti and photoperiod manipulation was required to make the cross, so it was not amenable to large scale production, but the hybrid grew quite tall. Of course, ‘Chinamington’, as the entire Kentucky Hemp lineage, is lost. ....."

if lets say you have grown cannabis outdoors in the midwest last few years bud rot has been very bad along with leaf spot disease that attacks many species in our area .....
just like inbreed lines s1/fem this does not combine well with acclimation. so many inputs besides the sun, temp., humidity, latitude triggering new expressions many dormant or now lost

& crop rotation ( pesticide ) usage by farmers.
can bulk seed sales take place across state lines ? will they state / governments switch from THC and seek other parameters for definition of hemp / medical cbd / thc etc. in the future ?
many questions still as hemp markets open up as competition itself breeds reactions. many counties, states, governments w/ balance sheets in taters. expect new regulation across the globe as this longterm liability thingy has said entity painted into corner~

I don't know how it is in the EU but think it is the same as it is in Switzerland: There are no pesticides approved for hemp and hence farmers are not allowed to use any kind of (chemical) pesticide on hemp no matter what. But then again, the varieties grown in the EU are well adapted to the local climate and usually don't need treatments. Sure, the density of hemp fields is rather low and at least hemp specific pests can't readily spread.
Given that non-EU approved varieties such as the new high CBD breeds are only allowed to be grown indoors (usually in industrial zones) in order to avoid/circumvent agronomic regulations (it's some sort of grey area taking advantage of a loophole in the current regulations) makes pesticide regulations kind of impossible to control other than the produce needs to be conform to corresponding requirements (basically food, tobacco replacement, and as raw chemical).

thanks! my friends in slovenia are expanding quickly on a few fronts and told me about organic practices
but across the usa farming belt things are different and must be considered. and many run hemp year after year without rotation so balance is key. IMO - crop rotation w/ forward planning w/ neighbors will be key regarding pollen. im talking massive areas now growing corn across midwest.

Can you quote me the law that prohibits using pesticide on a hemp crop? I never heard of this and I have grown hemp in the EU & Switzerland and elsewhere for decades outdoors by the hectare. Do "you" really grow hemp by the multi hectare in the EU or Switzerland? If yes for how many years?
Non-EU approved hemp varieties can be grown outdoors. I do it all the time.
Are you really a hemp farmer Only Ornamental? I am.
You talk like you have limited experience actually growing large quantities of hemp, excuse me if I am wrong.

thats interesting. so they are not allowing farm trials w/ high CBD strains, i figured so.
i expect the same type of rules soon in usa. the green rush underground > community > has not unfolded as expected when states opened up and i expect some new regulation will toss the new strain production assumptions into limbo

Different countries have different regulations on what is allowed, Switzerland I believe allows 1% THC? But if a variety is less then .3 or .2% THC it can be allowed in most of the EU. You can only get EU subsidies for EU listed hemp varieties, and as most hemp growers made more from the subsidies then from selling the crop, EU listed varieties are important to farmers.
In the end CBD will be produced by high CBD varieties with very low THC levels, why grow 10 times the area of plants to get the same amout of CBD? I have seen 25% CBD varieites and have heard of 30% CBD varieties, why grow hemp that yields 1-2% CBD?
Hemp is for fiber, hurds, seeds, CBD is a small by product that can be produced more efficently by very high CBD varieties and in the end will be. I also believe that any CBD production will be from all female seeds or clones, seeded Cannabis does not produce as high of levels of Cannabinoids as unseeded Cannabis.

When is it for food within the EU certain pesticides are not allowed to use and if it is, the farmers should keep to the strict MRLs, from what is allowed.
Better you can ask yourself is pesticide use needed when hemp is grown?If you have grown 1000s of hemp plants, which pesticide did you use in the field?
Never used any pesticides on Hemp or Cannabis, I only use IPM if anything.
And I would advise others to do the same.
Can you list the Swiss or EU laws that prohibit pesticides on Hemp?
I never heard of them, to be honest.

Don't know if any pesticide is used in Chinese hemp cultivation, but so far as i know the Swiss keep also to the EU regulations because of the trade.
I don't think that the EU has banned pesticides special for hemp cultivation, but several pesticides are not allowed to use when hemp is grown for food like Malathion, Parathion, 2,4-D as examples and it seems that neonicotinoids will be banned also in the near future.Pesticides which can disrupt the hormone system are not allowed either.
how about
biotic
abiotic stresses
breeding in artificial conditions ( indoors ) / lost directional selection towards environmental, natural inputs lost, change guiding diversity anything being lost ??
genetic variability lost. problems will " roost " in later generations and possible crop failure ie: pest, quality, yield, vigor, etc
