How does straw, HPOO and gypsum compare to HPOO, verm and gypsum?

Yes, but then you can always go back to spores and start over. Spores reset everything, so to speak.

Now, has anyone attempted to continue RR's work with PE6? Couldn't it still be stabilized in theory? I have no idea how to go about it but I would love to try.

It could be possible but would be quite difficult. The more generations that pass after the cross the harder it will be due to net loss of heterozygosity. That work should have been done at the beginning.

U would pretty much have to start it all over again. Or if u are lucky enough to have a pe like fruit that drops spores then u can clone that and try to isolate the trait

That's sort of what I figured. The gene pool just gets bigger over time.

The gene pool gets smaller over time. Every time you start a grow using spores from a single print. You are inbreeding.

:whathesaid: that's why stabilization needs to be done early. Because at first your chances are better, by limiting genetics carefully you can weed out a lot of the unwanted ones. But after a certain poi t, say 7 generations the amount you can limit is greatly reduced. At the same time despite there being a very small amount of heterozygosity, there is still a huge amount of variation. This means that unless you narrow the field early, it would take a fantastic amount of inbreeding to narrow out everything but the desired phenotype. This would take many generations and potentially destabilize the line. Much like what is actually is happening with PE.

I'm still not convinced this is PEs issue.

Why only PE? Why are no other strains destabilizing?

evolution and destabilization will happen because of pressure.
to effectivly breed and change ratios you need pressure. just selecting a fruit and printing at each generation will keep ratios the same.
to evolve you have to break genetic equilibrium we do this by appyling pressure and then selection.


PE is doing this itself( applying the pressure and forcing change)

in PE s case PE pheno Fruits dont print well so dont get to pass on their genes,  this puts pressure in 1 spot on the genes causing a shift!

as most fruits that go on to be printed have less PE characteristics this over generations swings the ratios and makes The PE pheno more uncommon at each generation if care is not taken with selection when printing.

U Dont need a printing PE. Use swabs to collect spores. Simple.
Numerous grows here show you that pe has spores but won't drop it. Who needs spores all over the substrate when u can just collect it with a qtip when needed

yes but the point is people still do collect and buy spores and not from selected fruits with swabs just any that will drop, and alot of the time they lack the defining qualitys of the PE fruit, and thats why it is de-stabilizing!

the point is who is controling what fruits spores  are selected from!

we should think of PE pheno as a mutation and mutations in a given genepool either become high in the frequency ratios and splits and is classed as a new species or the mutation is reabsorbed into the genepool and shows up here and there.

which way PE will go will depend on the people who do selection and this will ultimately decide where PE is heading.

PE is unique and has unique traits/faults that put pressure on the genepool, as PE provides its own pressure from its weakness in spore drops is needs no human to apply this pressure and natural selection will take place!
it will force the line to change 1 way or the other thats genetics and that evolution sorry!

pressure + selection = evolution

PE takes care of these 'musts' for breeding or evolving new varietys and does it itself!
without us intervening.
we are literaly watching evolution in progress sped up!
we are quite honoured to see it really and is a good experiment that shows evolution in real time.

if we are to breed varietys like pastys crs project first you need a goal to work towards!

pot luck dont cut it!

work out ratios ect and work punnet squares to know what you are looking for at each generation before you even get there!
this way you know the possibilitys before you begin.

first use backcrossing to a stud (a selected clone with traits you want) to increase frequencys toward the choosen stud, do this 3 times or cubing.

this makes your choose trait/s show up with precise regularity in the next inbred filal generations and limits the genetic dominances to the ones you have selected in your stud. each back cross is done by taking a single spore from the stud and growing out a monoksryotic culture, when colonised LC OF  the stud is injected to make the mono a dikaryotic culture of the studs genes and the single spores. the a fruit is then selected from this backcross generation with the traits present to select 1 single spore( prob best doing multiple monokrayotic single spore culture to test a few) again to cross to the original stud culture.

then this is repeated at each generation up till the 3rd

ratios work like this...
1st backcross generation spores- will have a reset of 50% stud genes / 50% single spore genes(remeber too this single spore is just a reset of the stud culture genes in spore form, they are very close as it was just a reset of the stud)
2nd backcross generation spores- will have a reset of 75% stud genes/ 25% single spore genes
3rd backcross or cube generation spores - will have a reset of  87.5% stud genes / 12.5% single spore genes

spore taken from the 3rd backcross will show 87.5% het to the dominances of the stud culture!

now if this is then line bred each generation will give lots of fruits with the required characteristic making selection easy.

backcrossing is a genetic shortcut used in breeding so we dont need large groups and lots of generations.

PE can easily be saved this way without recourse to starting from scratch.

line breeding is outdated, backcrossing help secure you your visual traits/ genetic markers easily.
use inbreeding in filal generations to open up the genetic catalogue then select a clone with the traits desired.
backcross to swing frequencys in your favour.
line breed to fully stabalise in a few generations.
this is the modern way

line breeding stabalizes the backcross work!
dont be fooled thinking you have to start from scratch.

it can be used to stack traits from different varietys in the same way.

pasty could use this to make his crs cross easily and then stabilze after achieving the result.
at the first cross he needed to select a fruit with  both traits and use as a stud culture as described above.

after cubing this clone, the spores taken from any just about any fruit at each  following filal generation in normal breeding  would show lots and lots of candidates to select from with the said traits and as the frequencys are already now in his favour and it would then be stabalised easily in maybe 3 or 4 filal generations. imo

working on paper like this wins.
it removes luck and works with numbers and science to see the possibilitys at each stage without doing a thing!
this ets you plan the whole project before starting!
all good breeding projects are done this way.
not many if any succeed by chancing the generations, as at each step you will have no marker to say if frequencys have gone up,down or stayed the same.( unless a large population is grown out at each stage)
also remeber unless there is a pressure, selection is pointless and normally just works like a reset keeping the frequencys basically the same.
this wastes breeding and breeders time! not to mention confuses and mixes the line so you cant keep track!
its not the right or done thing!
using a stud culture applies pressure at the genome  affecting exactly the traits you have selected for... the you carry on selecting for what you want.
this pressure + selection is what breeds the new variety...
selection alone can take hundreds if not thousands of years and not get far lol
evoulutionary rates go up and down just look at humans.
it the pressure applied that speeds the change.
the skill of a breeder is knowing how to apply pressure and what pressure to get a predicted result.
i.e grow in cold for cold resistance genes to show ect
it relys on a pressure.
a lot of breeding i see attempted dont take this into account so is slow and painful to watch.

a good place to start to learn in with the mendal pea experiments to learn how traits pass over.
then apply backcross teks and work the punnet squares to see if what you want is achieveable and how to go about it this show what exact traits will show up and in what frequency!

making stabalising though line breeding easy as you have lots of examples of the traits at each generation.



all we can do is be the selectors and guide things the way we want but in regards to PE and similar(redboy ect) it will take a collective effort of everyone and all need to understand the importance of selection when working with a strain/variety that makes its own pressures of change, breaking genetic equilibrium and forcing its own evolution by naturally favoured races passing on genes.

I would imagine, even with the nature occurence of evolution, its not like all PE comes from one source. Sure, maybe people on here get it mostly from the same vendor. But each person who is growing their own PE (or who has prints from years ago) can restart the cycle, so its not like some sort of finite strain, though, even if it changes aesthetically, id imagine it would only be for the better. Might look more like a classic cube but i dont see any reason for potency to drop or anything like that. Maybe like KSSS theyll look less abnormal over time, but they will still kick ass.
