hey everyone.
I am curious about the strategies that you utilize, as hobby breeders to get some progress and not fuck your germaplasm up.
From what i read - 1 breeding pair in each gen, down into ibl, select select, select.
Buuuut - surelly the vigor must go down the toilet at some point. I would guess about f4, but do not have experiences - I welcome your observations
You could obviously than cross again, (even with lets say f1 seed - so you stay inside chosen genetics) but it irks me, that than in fact you never have a strain - I am willing to understand the term widelly, but certainly the one thing "strain" must mean is that it puts out plants somehow more similar to each other than to those outside the strain and at the same time can be continued through time.
Seems very weird that a populace, that is doomed to degenerate after next 2gen should be called a strain (variations of hybrid Fs is not degeneration).
One solution is to keep two ibl lines and cross them in some intervals. Not a long time solution though. This is of course a theoretical question. In practice people will cross the shit out of everything, so not really an issue.
Somebody attempts syntetical populations? Wider bottlenecks?
Lets say, that we decide how many parents we are gonna keep. How do you maximize your efectivity at selecting? The selection on general growth wigor at seedling stage is obvious. What about breeding dwarfed plants to judge smell? Stress test with mold inoculation? Drought, hot and cold stress tests? Breeding for specific led light output? I read that plants tolerant to hotness also tolerate cold temps, that this tolerance is general to wider temp range. True? What is the highest density of plants you tried for selecting which trait that worked for you? What about growing many plants in big flat containers, can you see the root growth vigor in this way (most vigorous push less vigorous and grow bigger)? What about acclimating plants for outdoor? Anyone tried direct sowing to guerilla locations? Is it possible, have you found genetics that performs well in this setup? Anyone able to breed pest resistence over time to pests not being an issue (mostly curious about slugs)? Do you have a friend who is a long time hippie grower / breeder (we do not in europe)? how does he keep his strains?
Also do you have an experience at choosing a strategy that backfired?
What about autos, since you cannot keep moms, I assume that anyone regularly growing autos who has half a brain (my pespective - possibly I have half a brain) also does some breeding (pollen chucking IS a breeding strategy and has to be respected). Experiences with lines kept past f5? Any interesting recessive traits showing up? Auto x regular bred to full auto in f3?
I am sorry for such a broad topic thread, but I found in general the info availeble barely scratches the surface, again and again. In am tired of reading for the nth time about the most basic stuff.
You know some facts and you have some sources, the theory has some underlying mendelian logic. By providing these, you are doing a good thing for the comunity. There is no need to argue. Let your facts, sources and logic speak for themselves.
