What about the native plants we buy at nurseries, from my understanding many of them are cultivated are there any species that are not, but are widely sold?
Now lets go back to the venerable and often intentionally managed tomato.
Tomato without belaboring it as a wild plant. Is
a perfect blooming plant. What that means is left un-aided by pollinators a tomato will make pretty much the same plant generation after generation. All its pollination happens naturally without the need of others, inside the flower.
Intentional breeding ot tomato has pollen from one plant added to another slightly different tomato by opening the flower and adding another (tomato plants) pollen. Seed from that intentional breeding is then grown out and the best of the next generations plant is saved.
That selection proccess usually takes six to ten generations to fully stabilize, with subsequent selections made at each generation.
When all is said and done our new tomato plant is able to grow its merry way mostly unaided.
The 'new' tomato is still only an open pollinated
I'll leave it to others to do the tutorial for F1 hybrids.
Tomato is quite able when the season is long enough to self sow. And can live on as it did in the andean highlands, with nary a human hand at the rototiller.
Tomato is a good example, because I've read that the wild tomato is basically inedible. And there are tons of cultivars all a result of human intervention, dating back before Columbus. So any "wild" tomato one may come across is actually an "escapee", i.e. it's a result of human breeding.
However, from what I understand the Banana, which is also basically inedible in the wild, is the result of humans coming across a natural hybrid, although there are many cultivars today.
Basically, what that tells me is that there is no agriculture without purposeful breeding.
But I see I'm just going to have to find something really good that covers this topic, either a website or a book, my problem is, is that so much that I've read expects the reader to have a certain amount of experience, and I have virtually none.
This is one of the questions that popped in my head that started me down this line of questioning.
I have Cosmos in my yard that have spread without my intervention, other than planting the seeds earlier this year. Now suppose I want to buy some other varieties of Cosmos could this lead to a new "cultivar/hybrid" (I use these terms loosely since I'm still struggling to understand the differences, if any. BTW, I would not purposefully attempt to breed a new plant, but I have tons of bees here virtually everyday, so they'd do it.
BTW, how do you know if something is a F1 hybrid (as I understand it that means it's unable to produce offspring). Is this something put on the seed package?
