Great points have been brought up. I’m going to add this old link discussing the differences in hybrid versus open pollinated
The book referenced is of value not the link
"I was reading a book called Eco-Farm by the late Charles Walters of Acres magazine and I read something about corn hybrids and I wondered if it would pertain to Cannabis or other vegetable hybrids.
In discussing Open Pollinated corn versus hybrid corn, two samples were taken by a farmer from his field and showed the OP corn contained 19% more crude protein, 35% more digestible protein, 60% more copper, 27% more iron and 25% more manganese than the hybrid sample.
When his OP corn was compared to 4000 samples of hybrid corn from 10 midwest states in a single year, his OP corn contained 75% more crude protein, 875% more copper, 345% more iron, and 205% more manganese. The same trend has also been seen in the content of calcium, sodium, magnesium, and zinc. It could be said that the OP corn contained an average of 400% more of these nutrients.
Further testing confirmed the failure of hybrid corn to uptake certain mineral nutrients. Spectrographic testing at the laboratory of Armour’s Institute of Research in Chicago revealed the hybrid short of nine minerals. The hybrid failed to pick up cobalt and any other trace minerals. The core of vitamin B-12 is Cobalt and a lack of Cobalt is implicated as a cause of undulant fever and brucellosis and Cobalt is the cure.
In the opinion of this writer, hybrid corn merely masks poor farming by producing bins and bushels without the nutrient goodies that are really corn’s reason for being. In other words, quality versus quantity.
What this has to do with other vegetables "
