what does the f1 mean in cannabis seeds

F1, F2, S1 Seeds ??

the problem with the term "F" is its used too much. only 2 "true" ibl`s can produce a "TRuE" F1.

crossing an AK47 with another AK47 from the same line but from a differnt generation makes no difference to its name, ITS STILL AN INCROSS. "from my knolage"

im not sure but i think AK47 "F1" is an outcross. recombining the outcross with itself in any way is a "selected incross", not an "F"

S1 is first generation "self" polinated seeds. only 1 female plant is required for making S1`s

quality will be down to your selection and taste. some plants dont combine nicly..others do. this is because of dominant traits

use 1 male and 1 female to minimize pheno`s in seeds. "dom traits" will mean some plants wont mix well. so you might have to change the farther .

The seeds produced would be inbred F3 (the 3rd filial generation). we think no doubt someone will correct us if this is wrong.

rick: ANY cross between x2 different plants is an F1 (the 1st filial generation)!!

Only when two separate stable/homogeneous parent plants are used, then an ‘F1 Hybrid’ is produced.

Hope this helps

usin a f1 plant, and going back to it with a f2 is a backcross guys not a incross or filial generation.

to create a f1 you need parents from 2 non related lines. once combined you have the f1 generation.

grow the f1s , select males and females, pollinate and resulting seed are f2s, a filial generation. do the same with the f2s and you get the 3rd filial gen or f3s and so on.

backcross, is takin a plant from any generation and goin back to a previous generation, no matter the plant number.

s1s are selfed seed, take a plant reverse it so it makes male pollen, take that pollen and polly the plant. seeds should all be female.

you should get female seed of kalimist x sourdog. resulting seed should produce female plants. they wouldnt be s1s, as the km wasnt selfed. you did a fem outcross, and if theres a term for it i havent heard of it.

f1 + f2 = f3, while makin since mathmatically, is a bit off the mark. its a backcross doc, BX1 would be the resultin seed.

WOW. I hit the magic question.

OK. I am still unsure.

Let me explain how I came about the plants I am using.

I bought F2 AK-47 seeds from Spice Brothers.(at a discount) I already had F1 AK-47 seeds from Serious Seeds. I grew most of them out and now I have a Female F1 from Serious and a Male F2 from the secondary breeder.

I don’t have the luxury of having many to choose from for traits and whatnot. I have one Female and one Male.

So, from what I gather from your posts. I will have a 3rd generation. F3s? Not that the F or S # really matters to me that much. I won’t lose sleep over it but. I would like to know what I have when all is said and done.

Keep it coming. Its a good and educational read.

..lol. we didnt mean that at all.

The generation after f2, in the same line, is usually f3,, backcross or not šŸ˜‰

f1 female mated with a f2 male, you are takin a plant, the f2 male and goin back to your f1 female, hence backcross. this is the first backcross, BX1. your seed would be ak47 bx1.

Doc, so your sayin, a f1 plant crossed to a f2 of the same line is a f3? not sure im followin ya, or are you sayin since its a backcross its a 3rd gen, which your callin a f3? i thought that the only way to create a f3 was a filial gen of the f2. line me out bro

wasted on the way
WTF is this??
originally a Bubba s1 (f) x Bubba s1 (m). yes,male ( full siblings cross)
An outstanding female (Peyote Purple) was selected from this cross and crossed to 4 brothers.

i really dont think the term is used in the MJ field. when ya search, all i find is it used in the medical field.

back when i had done a generation with the jacks cleaner bx1, i was clueless as i am now what to call the seed. anyway i had asked here and had all kinds of labels tossed at me. no one really knew. i believe rez came up with the incross term at that time and has been bein used ever since.

he called the seed batch JCBX1 IX1 (incross one, or first incross, somethin like that) so im not sure if its right or not.

incross, ive heard the term around ranches here, cattlemen use it to describe a cross within a inbred line(meanin past what gen the herd is). they quit keepin track of the generations, and breed within a herd. they also use outcross when usin a bull from another herd of the same line.

would seem to me that breeding terms are used in many fields, with slightly different meaning.

Cannabis crosses are not F1s, so says science!

Phylos Bioscience:
Currently the way the cannabis industry uses the term F1 hybrid is wrong. An F1 hybrid (or filial 1 hybrid) is the first filial generation of offspring of distinctly different parental inbred types. Cross-pollination involving two true-breeding, or homozygous, parents, result in an F1 generation that are homozygous and consistent in seed form. There are very few, if any, true F1 hybrids in cannabis because every modern variety is heterozygous (highly variable). The Phylos genotype test can detect the level of homozygosity or "true breeding" status in a particular genotype. So far there are no completely homozygous varieties out of the thousands of unique genotypes we have tested on the galaxy. Who will be the first to develop two individual and distinct homozygous varieties and cross breed them in cannabis has yet to be seen.
Original post was from Their IG & FB pages.

My proposal, which is up for discussion, is as follows.

Some definitions to help the discussion:
Homogeneous is used to describe a kind of mixture which is uniform in composition. Whereas homozygous is a term used to describe the genotype of a organism in case of a particular gene, when that organism has identical or same alleles(or copies) of the gene present on both(for diploid) or more (for polyploid) homologous chromosomes.
Homozygousity doesn’t have to occur for every single gene in the plant, it just has to be homozygous for the traits you are breeding for, but it does mean that the specific trait you are targeting be identical across all associated diploid genes.

The basis of all of this is the individual chromosomes. Cannabis has 20 chromosomes paired off to make 10 pairs, including the sex chromosome of either XX or XY, which when combined makes up the entire genetic code for the plant. Alleles are the areas on a chromosome that have genes coding for a specific trait. The same gene code across an allele make the plant homozygous for that trait, and if the gene code is different it’s heterozygous.

At the level of genetics that most cannabis breeders work at the most they can determine is if a population of plants is homogeneous, or uniform in it’s phenotypes for a trait. Uniformity only requires that the population be very similar.

An individual on the original IG post stated that there were a few close to homozygous strains, so I contacted Phylos to enquire about it.
For the sake of transparency I’m including the entire email conversation, but skip to the end for the reveal.

"I was a part of the Instagram comments thread regarding F1 generation labeling accuracy. It was stated that Phylos Bioscience had found some (4 rumor had it) cultivars that were very close to homozygous, but hadn’t quite achieved that status yet. I’d like to know what those cultivars are if they exist. I am asking for this information in order to educate members of the Overgrow.com forums on genetics and breeding. The knowledge that there are even a few cultivars that are closer than most others to be homozygous seems to have their attention and they are learning genetics because of it! Thank you for your assistance in this.

Thank you,
Sebring"

"Hi Sebring,

Thank you for reaching out, and for following us on social media!

We’ve sequenced around 4,000 varieties in our Galaxy, so I’m not sure which those are off the top of my head, but I’m going to reach out to our science team and find the answer for you. I’ll be in touch very soon with more information!

Thank you for your patience while I gathered more information on which cultivars we’ve sequenced are the closest to being homozygous.

Here are links to Genotype Reports for some of those submissions:

Sumatra Tuk Tuk
https://phylos.bio/sims/sample/genotype/egwxej8w

Paraguay 3 1996
https://phylos.bio/sims/sample/genotype/d8v4nn86

Nicaragua 4

Thai Stick
https://phylos.bio/sims/sample/genotype/1oex01dg

Gold Colombian
https://phylos.bio/sims/sample/genotype/y8nq2rn8

These submissions are fairly homozygous, but still vary at around 5% or more of the sites we examine. You can find more information on the sites we examine through the Open Cannabis Project.

Let me know if you have any other questions!

The submitters of these strains are David Watson and Ma Dang.

Ma Dang has contact info listed.
D. Watson doesn’t have contact info, but I believe he is "Sam the Skunkman" and you can probably track down his contact info. @Sam_Skunkman

Be warned that because both individuals have submitted tons of samples, it’s not likely that they have seeds or clones available. Although, they probably know where and if they are still available in the wild.

*If any of this information is inaccurate please let me know and I’ll fix it*
