Confusion about crossing 2 varieties

[420benny]

I have read about lots of crosses here between different strains and am wondering about something. Let's say you cross a female White Widow (strain A) with a male AK48 (strain B). The seeds you plant from this are f1 (1st generation) Some say these can be unstable. What do you do for the next generation, f2? Would you pollinate one of the f1 females? If so, with what pollen? From the father plant or one of the f1 males? When a cross is mentioned, is there any order to how it is written? Meaning, if the female was WW, is it listed first or second, like WWxAK48, or AK48xWW? Lastly, if you cross the same 2 varieties, but choose a male WW and a female AK48, are the seeds and resulting seedlings any different from the same 2 strains crossed the other way?

I "personally" do not breed seeds--I think that is better left to the professional breeders. However, if you do, there are some excellent stickies here to get you started.

I have moved your thread from the propagation section to the breeding section. Hopefully you will get more/better answers than mine .

I'll take a stab at yer questions...

when giving a description of your cross, you say the female first, and then who it was pollinated by...

(female parent) x (pollinated by) (male parent) to give you F1's of whatever you want to call it

F1's are said to be "most unstable" because the greatest number of different pheno's can come out in the children (size, coloring, indica or sativa domminant, growth rate, etc.)

F2's are more "stable" (growing more similar to each other) - F2's are made by taking a male and fem of these F1's and breeding them... now, desired traits of the F1's are looked at to decide on which plants to breed. the dominant traits of both F1's will, most likely, be the domminant traits of the F2's... across the board, meaning, it will be more the "average" traits of all the F2's, unlike the varying traits displayed between the F1's...

hope that explained things to ya... mutt would be able to explain this MUCH better than me... in other words, take his word over mine... but as far as I know, that's how it is....

Thank you, that makes sense.

I guess that you could say that I have had contradictory experiences.
F1's will "usually" appear somewhat stable, or you will have "fewer" phenotypes than f2's. The f2 fillia is where "I" have most often seen the widest pheno' diversity.

from...hXXp://en.wikipedia.org/wiki/F1_hybrid

In agronomy, the term “F1 hybrid” is usually reserved for agricultural cultivars derived from two different parent cultivars, each of which are inbred for a number of generations to the extent that they are almost homozygous. The divergence between the parent lines promotes improved growth and yield characteristics through the phenomenon of heterosis ("hybrid vigour"), whilst the homozygosity of the parent lines ensures a phenotypically uniform F1 generation. Each year, for example, specific tomato "hybrids" are specifically recreated by crossing the two parent heirloom cultivars over again.
Gregor Mendel's groundbreaking work in the 19th century focused on patterns of inheritance and the genetic basis for variation. In his cross-pollination experiments involving two true-breeding, or homozygous, parents, Mendel found that the resulting F1 generation were heterozygous and all phenotypically resembled the dominant parent plant. Mendel’s discoveries involving the F1 and F2 generation lay the foundation for modern genetics. Today, certain domestic hybrid breeds, such as the Savannah cat, are classified by their filial generation number. (An F2 hybrid is a cross between two F1 hybrids. This second-generation cross does not produce consistent or vigorous plants. )

there...see?... told u I prob didn't know what I was talking about...

like I say in my sigy... "I just grow the sheet..."... I don't claim to be a creater of universes....
