I just hope they will eventually live up to any expectations. I think it's doable to create a closet-IBL using careful selection, luck, and most of all time. I hope the F3 will be narrowed down enough that I at least reached a point where I can select multiple plants that I think will help reach the goal.
F1 was simply to mix the chunk genes with the CH genes, this is the "create/generate variety" step, the first step of breeding a new variety through crossbreeding.
F2 was a pheno hunt round. F2 is where gene pairs from the F1's parents recombine, which in practice means you get some traits of which the genotype is from 1 of those original parents. For example the short flowering, short structure from CH and the taste and vigor from the chunk and not just the result of mixed gene pairs like in F1.
With a complete gene map, more insight in the DNA (something common for other species but not as much for the largely illegal cannabis) and a large enough plant count, I could select two of the F2 and create a super stable F3. (as I layed out here:
https://www.rollitup.org/t/when-is-it-considered-a-new-strain.842812/#post-10907966 )
That's obviously not the case, so I need to guesstimate it instead, tracking inheritance, guestimating dominance and genotypes. The more plants you got the more obvious it all becomes, but that can be partly solved by simply doing more runs, possibly, if needed, of the same generation (especially if you cross two very different strains which isn't actually the case here).
Point is, I kinda just got started with the essential breeding part and a lot depends on how the F3 turns out.
So far, I really like what I see though.
Those who followed the previous round from the start probably remember that dark green P-F3 I popped for fun amongst the CHxCH, this one:
I still got it, topped it a few times, barely gave it any attention, it's in the corner in one of my veg boxes and not under the T8s... and it's well, pics:
Some of the topped parts I put in a glass of tapwater about 10 days ago, behind a window, in daylight.
Still lovely green, and...
I kept it in case it was a fluke (the vigor not the rooting in glass..), it's flowering already cause it's been in daylight.
The F3 plants. 4 in the center in the top row are from P-F2-4 (was in hempy, sweet skunky), most of the rest is offspring from the swan. They took a 3 feet fall shortly before the picture, drop test passed
It's obviously way too soon too tell, but the offspring from the swan look very much alike. Any difference in branching / apical dominance could be solely due to difference between male and females. It'll be interesting to see if they end up with sativa dom leaves like the swan.
Some more from the swan, from nr4, and nr 19. Nr 19 was the most frosty, fastest flowering, and hardest nugs. Apart from that it wasn't what I was going for (it has even less of the haze/sativa genes) but I want to see how the male influenced that so popped some of those too. They are a node or two behind cause I popped them a few days later.
Another one I still got is the swan (P-F2-#22) (just in pic above on the left), so I got the option to do a backcross to that one. Actually, good chance I will do that on the side. If all else fails, I would still have a backcross of the swan.
This is the most unlike all others, from #4 (just a little more slender leaves), looks great though and I hope it will soon look more like the others else I'm going to have to kill it.
