This is:

The seeds are marked F1. And these seeds are already fruitless in the next generation.

This is how the breeder would now give a spade on the sushi! Potatoes do not have fruitless seeds if they are collected and stored properly. Pollen for him is not a carrier of genetic material and "GMO’s will not work.
And, yes, the breeding line provides high yields and resistance to diseases in the following order:
Micro-club-miniclub-first soil generation-superelite-superelite-elite-carton in store
Minicluben, for example, gives up to 10 generations (years) protection of offspring from a number of diseases at the genetic level. But it will be sold to you (if only by acquaintance) for a price of 50 rubles. This is genetic material, it is unprofitable on the seedlings, so it is reproduced to "superelite" with a minimum of five years of yield guarantee and only then sold to farmers for 15 p / kg on the seedlings. With a yield of up to 50 potatoes from one bush, it quickly pays off. And for decades, a single variety grown by the landscape without changing the seeds will eventually yield a harvest in half a glass of peach from the bush (tested in childhood, very offensive for parents)
