luckily for me, in the plant world, reproduction means "propagation".
Plant propagation is not necessarily achieved by sexual reproduction. if a breeder can take cuttings (ie asexual reproduction) and have them ...
a.) produce and grow on their own roots or,
b.) successfully graft to established root stock, then a breeder should have successfully reproduced their creation, at least that's what I gather from reading the links provided anyways.
In sexual reproduction, I assume, it's all about the marketable trait and how well the retail seed stock breed true for this trait.
One way can be achieved by doing the actual breeding work. working a trait into a line. there are plenty of threads here on that topic.
Another way is the F1. When two homo-lines crosses for the first time it creates something new. not the F2. Just the F1 is the homo-offspring. not pot grower's multiple poly-hybrid F1's either. Google the grape tomato variety called the "Santa Sweets F1" the F1 is part of it's legal name. I think it's a plum tomato crossed with a cherry tomato.
I have a few seed catalogs sent to me seasonally and, I can't recall ever seeing F2,3,4,5... attached to seed stock. It's usually either an F1, an Heirloom variety, or a new variety.
stuff that is usually sold from the live plants sections says it either grows on it's own roots or is grafted ... and grafted roses are usually on regionally specific root stock, at least in the literature that I'm looking at.
I've taken cuttings from grafted roses in the past and successfully had a Mister Lincoln growing on it's own roots and actually blooming. But, it didn't like it though and never really took off. After two years it would produce super small blooms and really weak "canes" for a climber ... That's why I'm sure the breeder meant for this type to be grafted.
I also have santa sweets F1 saved seeds, the F2 generation, so far all of them have bred true. They produce a perfectly good grape tomato. I have read however, that the F2's are only supposed to breed true 91% of the time and the subsequent generation's homozygocity deteriorates even further with every generation. I assume that's why I cannot find Santa Sweets seeds labeled "new variety" out there. make sense?
