"In an article titled “The Curse of Knowledge”, it’s noted that as a person learns more about a subject, it becomes increasingly more difficult to discuss that subject with someone who doesn’t posses that knowledge. It simply becomes harder and harder to empathise with them.
This means that the more educated and passionate you are about a subject, the harder you will find it to discuss or teach it to others. This effect is one of the cited possibilities for why teaching is so difficult a career, since it means that eventually teachers will become more and more disillusioned with the endless wave of perceived stupidity they’re forced to endure."
I'm guessing that's partly why you won't find many breeders eager to discuss these topics.
Exactly. I still call my crosses F1s for practical purposes, but in a "few" years when I'm done creating two IBLs and created an F1 out of those, I will surely specifically mention it's a true F1 as then those who care instantly understand what that means.
Breeders and seed makers found out you can sell something that is uniform enough to consider stable enough for growing, without actually breeding traits true (homozygous). Backcrossing for example. Continue crossing back to a plant and you usually will end up with something that looks mostly like that plant you cross back to. Doesn't mean it a truebred of course, not necessarily even for traits because dominant heterozygous genotype and dominant homozygous genotype are the same phenotype so either will do for growing.
That's the difference right there, bean sellers aim for a certain limited amount of pheno variety (uniform and stable enough for growing) and not to create a stable strain others can use for creating and selling true F1s. Considering the amount of commercial breeder wannabees who start seed banks smelling money I can't really blame them for not releasing the Ps of their F1s.... I will, if I ever get that far
