a self pollinated F1, what might pop out?

S1 = F2?, so all S1's are F2's but not all F2's are S1's?
plant maturity suddenly shifted into high gear
amber trichomes popped out quickly at the bud tops
cut at 74 days, 10 1/2 weeks, final pic out of chamber
hard to tell too much from vaping sugar leaf
but the taste was like the smell, sweet perfume, bodes well for the cured bud

Here is a tutorial if you have no clue what an f1 really means.

Keep in mind that chart is not referring to an entire plant but gene pairs.

http://kdcomm.net/~tomato/gene/genes2.html

"After selfing, each subsequent generation reduces the amount of "unlike genes" in half until they are virtually all removed. Once the chance of unlike genes is gone, the populations will be all homozygotes."[sic]

^^^ a sibling backcross, that gives an air of dignity to my orignal hermie grow

a quick summary of results, and a new addition
#1 - very good femme, no hermie trait, good flavor/effect
#2 - very much a hermie, and had nothing but bad traits
#3 - good femme, no hermie trait, good effect/not much for taste
#4 - a male, strange but true, maybe a rare event, or a strange hermie
#5 - very good femme, hermie trait just sterile roosters. good effect/excellent taste

and leads to #6 which i started early - by my standards - have 2 grow chambers
3 1/2 weeks of flower, doing a LST, and looks damn nice
but it's a hermie, it has the strong hermie trait, started early
but does give a number, 3/6 clean femmes, a 50-50 throw of the dice, just like reg seeds

just be careful about labelling your ladies non-hermi too soon.

I wouldn't run a room just yet I guess is what I am saying..

I have had what I thought were stablized hermi-crosses go bi on me under stresss..

Ruins your day....

i wouldn't call this a stable set of seeds, but it's really no worse than reg seeds
or maybe a little worse since the hermie flowers are sometimes stealthier
but the mom did have a pretty good effect on my anxiety, and that trait does seem to be present in most of the offspring

that time of the week again, and sadly, this is truly a hermie
well, better than an outright male
a few bits of pollen have struck, plucked off a few young seed pods
bud regrows from damage, thinking this may be a helpful thing to do
still looks good at 4 1/2 weeks, just have to keep up for the stretch run

it may be a hermie, but it's not as bad the parent
less roosters as time has passed, not so bad to keep trimmed
a few seeds showing, but very few, pic is a bit green, cheap camera didn't give the truest color

6 1/2 weeks, not too bad for a hermie grow
it gave up on throwing the male flowers, they've pretty much dried up
that's a first in my hermie career, such that it is
they normally throw and throw right to the bitter end
point being there is variety to the intersex trait, there are differences

there is variety to the intersex trait, there are differences

there certainly is in a range from sterile bananas or even sterile flowers which dry up like you experienced to varying ratios of male to female flowers

most controversial would likely be the "100% male" herm which some reference

i got a "100% male" from my hermi X
& a couple of females which wont stress-herm {100% female?}

femmes that won't stress herm seem fairly common
the intersex trait turned off by some accessory genes?
otherwise you'd think that some breeders would have some 0% hermie breeds
which could exist i guess, haven't seen the claim though, just very low hermie rates

7 1/2 weeks, the magic time when ripeness is just around the corner
which is likely another few weeks, still a lot of white pistil
and the vanished roosters have come out again, knew it was too good to be true
not a lot, but enough to keep me fine combing the whole plant
which is plenty of work

8 1/2 weeks, another hermie stretch run
stretch run because there are few roosters popping deep in the bud
which makes it a bitch to pop them out easily, mist and pull, and pray for minimal damage
other than that, it looks pretty good, got some cluster budding going on
my name for bud growing out of bud, main cola shows it with the new white tips

9 1/2 weeks, the cut has been done
trichs had clouded up, a 50/50 cloudy/clear mix
side bud sampled, and was very suprised because it looked indica(mostly)
more sativa lurked there than met the eye, interesting
not a columbian/mexican of old, but i'm making progress
some seeds, but mostly seedless, it was worth the trouble

i have popped another of my F1 S1's, which has been in the grower a while
9+ weeks of flower actually when this pic was taken
winter has sucked away a lot of energy this year, but spring has sprung and nothing says spring like the green
so what i got was a extremely sativa pheno, at least from my point of view, been a while since i've seen a sativa up close
low grow chamber temps, probably not ideal for what looks to be a tropic type of plant
yields are going to be very bad, such is life

Nice work, I like it when people try and see if the things everyone believes are really true.
The real difference is inter-sex expression and do any of the S1 seeds not have inter-sex genes in them? Wether they express them or not all the plants from the S1 seeds do, I would bet.
If you take the seeds and grow plants then find 50% inter-sex how do you know the other 50% are not inter-sex but not expressing it without the right conditions they may require to express the inter-sex?
My growing history tells me that if you use inter-sex plants as parents the progeny is inter-sex, visible or not, in fact visible ones are easier to eliminate. I am not trying to say the smoke is useless, we have all smoked inter-sex plants we liked, I am saying that if you can find a non inter-sex plant with the traits you like it is better to use then an inter-sex one. Try cloning and testing the s1 plants with stress testing regime and see what happens to the non "inter-sex" plants from the S1 seeds, I bet most will show inter-sex...
One thing for sure, as you may know, many people think you just need to self a female to get the same exact type plant, as you can see selfing a hybrid Cannabis plants is more like making F2 seeds, they will express all the parents used to make the hybrid, just like the S1 seeds do.
All the best,
-SamS


so far, what i see is a 50% chance of a good female
i don't think your chances will be any worse, may be better, but it's a definite crap shoot
if you're a grower that doesn't mind checking things very closey, they are worth a shot
no worse than reg seeds provided you were planning on tossing the males

thanks for the replies chumsworth and sam, this is definitely a experimenter's type of thread
it probably doesn't make too much sense if you want the best genetics, some ugly things seem come along in S1's
but i just had to know, genetics is another addiction in addition to growing
speaking of ugly, these crappy little buds look to be coming out purplish black, though i used to think of black buds as the holy grail with the old stories about black african back in the day
