Curiosity: Genes with transplants or protected veggies

[Dewdrop]

I'm curious, is it possible we are unintentionally selectively breeding for different genes or traits by raising generations of vegetables indoors or in greenhouses, and then transplanting them into the garden or fields afterwards?  Would there be any unintended selective breeding for or against traits by direct-seeding, and raising or protecting vegetables in grow-tunnels over generations?

I have  crossed one fruit of my tetsukabuto out with a male flower of my maxima (justynka F1 X green hokaido)  wich growed in greenhouse.

the plants of the  varieties (justynka F1 X green hokaido) out are not given fruits and the plants are very little and weak, the alone plant of this varieties to have given fruits was in greenhouse,he was more vigorous.I think that this seeds will be very tolerant at the heat.

It is possible, but unlikely. Most of the plants you would grow indoors or under cover would be self-pollinating vegetables, like peppers, tomatoes, and beans. Those species are very genetically stable. Species which rely on cross-pollination (such as corn, cabbage, squashes) would be more likely to adapt to conditions. The most likely change, if any, would be germination rates in soil. When direct seeding, weak seeds would tend to rogue themselves out, and not be carried into the next generation. When germinating those same seeds under more pampered conditions, the weaker seeds could inadvertently be increased. The point is academic if you always grow vegetables the same way year after year, or if you don't save seed.

i think any time you apply some selection pressure on a population you can get unintended effects. you'd have to keep an eye out through observation as to what is going on. myself not being much into indoor seed starting and also don't have a greenhouse or even a coldframe so all the planting i do here is direct into the garden soil or we are using starts from someone else's greenhouse.

the points about plants needing to be self-pollinating and self-fertile would be key there.
