whats the diffrence between these? i relize how its interbread down and each time it goes from f1-> f2 -> f3 .... but is there any quality diffrence?

I'm no expert but i think the main difference is the stability of the seed. If you have 10 F1 seeds, you might get 5 that look and grow the same and 5 that look different and have different characteristics(quality, smell, taste, yield, etc.) as you continue to breed the strains that have the characteristics that you want the seeds become more stable. So when you have 10 F3 seeds you might get 8 or 9 that look the same and have the same characteristics, thus the strain is more stable.
I could be wrong and if i am i hope someone corrects me.

he what i understand....

starting with two stable parents we cross A with B.

we now have AB - F1. this generation should be a stable strain, taking 50% from each parent. if you plant 100 seeds side-by-side of this generation they should all come out the same. a lot of seed bank seeds are F1's.

now when we take the F1's and grow some out, take a male and female and breed them we get F2's. F2's are supposed to be the most unstable. with F2's any traits may appear. all the previous breeding stock can show itself. it's basically a "free for all".

now we start doing selective breeding. by picking out matching traits of males and females of the F2's we breed those. this gives us F3's. now we take those and breed the SAME matching traits as the F2's. we should end up with a more dominant selection of the desired traits.

if we continue picking out and breeding males and females of the same seed stock with matching traits then by the time we get to F6 we should be stable.

hope some of this made sense. :blsmoke:

i think it might be the oposite way.( dont know anything about it but it makes sencE) last time i checked F1 seeds where the high quality ones and F2 anf F3 were less quality

Edit : read FDD's post thanks for the info that seems like it makes sence. now i know why the strains are priced diffrently

i just read up on it:
f1 seeds are offsprings of plants that are from 2 different pure strains
f2 are offsprings of said f1 plants
f3 are offsprings of f2 plants

apparently they become less and less consistent with genetic traits so the further down you go
on the list the less predictable your plants' characteristics will be

f1 plants realize hybrid vigor where it grows faster than pure strains but apparently, once
bred with each other produce f2 plants which aren't as genetically stable so the plants may
look different from the same seed stock and f3 follows the pattern down another notch from f1

if im wrong correct me because then i'd learn something

F1s are no more stable than F2s or F3s etc. It all depends on what the parents are. The more diverse the parents are the more diverse (less stable) the F1s will be.

P1-The name of the parent to which a hybrid is crossed in a backcross.
F2- generation : The progeny resulting from self hybridization or inbreeding of F1 individuals is called Second Filial or F2 generation.
F1- generation : The progeny produced from a cross between two parents (P1) is called First Filial or F1 generation.
inbred line- (IBL) - A line produced by at least five generations of sequential inbreeding, self fertilization or backcrossing accompanied by selection within and between lines so that the individuals are considered to be homozygous, or nearly so.
Homozygous - An individual possessing (receiving from parents) identical alleles for a trait is said to be homozygous or pure for that trait, e.g. plant with RR alleles is homozygous for the seed shape. A homozygous always breeds true for that trait.
Phenotype - The external (morphological) appearance of an individual for any trait or traits is called the phenotype, e.g. for seeds, round shape or wrinkled shape is the phenotype
Capitate-Botany: forming a head like mass or dense cluster, as the flowers of plants in the composite family. Enlarged and globular at the tip.
Dominant - said of an allele which by itself alone will produce a particular phenotype regardless of which other allele may be present on the other matching chromosome of the diploid pair; thus it takes only one copy of the chromosome to cause a dominant trait to be expressed in the phenotype.
Genome - the total genetic information possessed by an individual, a breed or a species.
Genotype - the invisible genetic makeup of an individual organism, which includes alleles which may be recessive and therefore have no visible physical expression.

the stabalizing part comes from back crossing (bx or cubing as its also called) say you have breeders pack pop and get some males and females and you take them and breed to make a f1 beans now you pop the f1 from here you can take and breed two new f1 plants to create f2's... or you can take your parent from the 1st breeder pack and breed it with the f1 that has the most similar traits your trying to stablize do this 4 more times with the one same parent and you should have pretty stablized seed line

you all make it seem simple.... its not..

anything can happen. you can get more potent,or weaker strains. can get 50% -%50% mixes, or 90% -10% mixes of strains or any combinaton.
if they came out 50/50, where do different phenos in F1 seeds come from?....

also, lots of strains/parents dominate when bred.
you need to make them, grow them out, and see how the parents effected the cross.

f1,f2,f3 just refers to the lineage.

its all about selection, period.

if you are selecting for specific traits and breeding only the offspring that exhibit those traits, then the traits will not be lost. but my point is you dont automatically lose vigor and potency and other traits. F1s are fun imo because if you make and pop enough seeds you are going to eventually find one that resembles the mother and that resembles the father. F1s are kinda like people. if your mom and dad make 100 children, none of them will be exactly the same as each other, and some will resemble the mother more than the father and vice versa. thats where the people analogy ends though, because the F2 generation of people would be imbred :p but F2s are also nice because you dont know what your going to find, recessive and rare traits/phenos are what i look for with F2s. starting with the F3 generation and onward i expect stability from a strain. i believe i read that DJ Shorts Azure Haze uses a Blueberry F5 or F6.

good luck! asking questions is how we all get more informed ;)
