Can someone explain, or post a link that has info about what is classified as a F1,2,3 or S1,2,3 or BX1 etc?

I know its a generatiinal thing to keep track of pedigree, and I have a vague understanding, but over all the years of reading I never really dove into keeping family trees.

Thx for any info

If you breed a male and female the offspring are f1... Breed a male and female from the f1s and your making f2s..breed a male and female from f2s to make f3s..and so on...a back cross is like breeding the f3 back to say the f1 and so on....go to breeders section and you will find what your looking for..hope this helps

c1 is a clone first generation of cut from the seed, c2 is a clone cut from the clone c1 , c3 is a clone cut from the clone of a clone, and so on.

F1 is the result of cross two different homozygous lines, result in a heterozygous hybrid. It can be considered the result of outbreeding.

F2, F3, F4, etc,etc, are inbreed generations (brother x sister, or even sister x sister)

BX1 (or BC1 or N1) is the first backcross generation. If for example you pick a plant from the F2 generation (which was brother x sister) and cross it back to a parent from the F1 generation, it's the first backcross generation. If you cross the BC1 to the same F1 parent (now grandparent) it's an BX2 and so on. Read my thread here for more info on backcrossing (backcrossing to F1 is a bad idea..) : http://rollitup.org/t/backcrossing-your-own-variety.840329/

S1 refers to to the first generation of offspring from a single plant. I.e. when you pick a female and reverse it to produce male flowers, and use the pollen from those to pollinate its female flowers, you get an S1. If you would repeat that process with a plant from those S1 seeds, you'd get S2.

Id depends in who you ask too. For basic breeding its all ducks in a row.

When you start getting complicated with breeding determining what to call a generation gets complicated
