Dominance When Breeding?

[norcallefty]

I was told if you cross blue dream with something that it ends up just being blue dream or all the traits of blue dream because its a really dominant strain/pheno etc...

In this sense is it possible to say cross blue dream and sour d but have plants that appear to be pure sour d or pure BD even though they are supposed to be crossed? Im not super familiar on how the stabilization and breeding works to get very particular traits and feature you like.

any info would be appreciated

it's called selection. you make a cross, then you grow the seeds, then you select the plants with the traits you like for further crossing.

I dont have any experience with breeding, but there are some pretty experienced guys on here that have explained breeding very well if you searched the breeding forums. I dont think it will be as simple an answer as oh this is blue dream... It will be the same in all crosses. One of the main things would be whether the blue dream was from seed or if its the clone only, id be willing to bet that there are multiple versions of the clone only too. All probably providing a little different outcome if bred and mass seeds were planted to discern the difference

Martha focker beat me to it, i was also going to say give it a go if you can and see what comes out then keep the ones you like

scroll back a page or two. I started a similar thread title dominate strains. Dank frank posted some good stuff.

most ppl fuck this up and it's important to get it right.

take two strains(a,b). hybrid them. these are f1's. (a/b).

most ppl run f1's looking for selected phenos to run.

wrong.

you need to take the f1's and cross them to make f2's.

only when you get to f2's ( I actually refer to f2's f3's etc. as fx's as opposed to the original f1 beans).

will you normally get strong phenotype separation.

in the fx's if you run enough seeds/seedlings you can get some seedlings that are pretty much identical to either parent ( a,b). if a is dominate and you want b phenotypes you will need to run a lot of f2's to get a very few recessive ( b) phenotypes.

if you run f1's looking for type b recessive phenos you will have a much harder time than if you do the preliminary and most important step to getting phenotype separation; make f2's and then start your pheno search from f2 seedlings.

if both a and b look similar how can you tell which one is a or b leaning? you can't. that's why I use different looking parents in vegetative growth so I can tell in the early ssedling stage which ones favor a, which ones favor b and which ones look like a melding of a and b.

run a lot of f2's. you can have 20-30 seedlings in one small pot. cull everything ( snip) that's not exhibiting the attributes of the desired pheno.

^ this is your starting point for your personal in line breeding project.

most ppl neglect making f2's and they don't have the phenotype separation to select from.

selection is only as good as the phenos you have to select from.

without using f2's cubing bx's are usually a failure due to no phenotype separation to make selections for the cubing bx project.

cubing works using lots of f2's for selection. cubing does not usually work without the preliminary f2 step.
