Questions about crossing strains

Hello everyone...

Former OG member very happy to have a place to still ask veterans some of the crazy things going through my brain.

I am currently growing out some Sensi g13/hashplant, Dj short blueberry, and sensi afghani #1. Im interested in trying to find a g13 pheno to keep as a mother and improve through crossing. Heres my thoughts after reading a lot of forums last night.

a) My best G13 pheno female X blueberry male

b) G13 X G13/ Blueberry male

Now my question is on the (B) cross...do i have to cross the g13/blue male back to the same original G13 mother plant or can it be original seed stock that i got with the mother plant?

Anyways i figured id then grow out a lot of those (B) crosses and look for a good keeper mom. What else can i do? any suggestions? Also ill likely do the same thing but replace the afghani with the blueberry.

I'm not 100% sure and I'm still learning abou breeding. When making your crosses they are going to result in a Hybrid cross with seeds producing the F1 generation. Plants should resemble both parents in this generation. There are going to be traits that you didn't see in the mother or the father. Select your best plants from the F1 generation and make more seeds. The next generation will be F2's. From what I read alot of the traits will show in this generation so you should be able to choose what you like and what you don't. If you keep selecting the best plants from each generation sooner or later the plants will start to lose vigor and maybe start showing mutations due to inbreeding. Inbreeding is good for trying to find dominant traits from parents but it's not good to do it for a long period of time. I'd say keep track of your traits from each generation for the first few times of crossing. Once you find what you like then start your backcrossing. Cross selected plants with plants from the F1 generation or the orginal mother if you can. This is why it's important to keep a clone of the original mother so you can go back and lock down traits. Like I said I could be wrong with all of this and if I am someone with knowledge correct me. I'm still learning and reading about genetics. It seems easy but it's isn't.

sorry, but I dont fully understand what it is you are asking. If I have understood things correctly, you dont strictly have to cross the g-13/Blue male to the mother plant, it could be crossed to either. If you were trying to retain the traits of the motherplant then yes, cross back to that plant but if you are simply creating seed to grow out in the hopes of finding a mum then perhaps cross back to seed stock, it'll give more variation. In order to give you a better answer you would have to list what you want out of the finished product etc. also, I dont have squat experience with hands on breeding though, just read alot on the subject....

Backcrossing with the mother will give you a seed stock that more closely resembles her.. so yes ideally you do want to cross with the original mother.. crossing between F1 hybrids will cause a lot more variation- some might be good, some might be bad, but either way more of the plants will differ from the parents.

cool thanks for the input everyone! i was originally planning on crossing my best G13 phenos (F + M) which would make my F1's.

so.... P1 G13 X P1 G13 and that would produce f1's....then

F1 G13 X F1 G13 which would be F2's...however, Ive looked at a lot of other people on here that instead of using that F1male, they replace it with a male of a different strain. Im not to sure why except that i figure it would give less phenos than a true F2 cross.

So now is that still called an F2 if you bring in a new male strain or is it something different?

Also it would be at that point that i was thinking id backcross a male plant back to the P1 female. Im mostly looking to increase yield, potentcy, and smell and figuring out the proper way to breed cannabis. Ive read a lot of Rez's threads and other breeders on here and i have the book Marijuana Botany but im just getting started.

Also when im looking for plants to cross do i use plants that resemble eachother or phenos that dont resemble eachother.
Right now i have 2 G13Xhash (1 Fem 1 male) that really look great, big broad serrated fan leaves and a nice dark green. should i use both of them to cross or should i use the female and use a male that looks different to her. I guess im a little confused about how the plants traits get mixed in future generations.

Anybody with some experience have any input? Thanx

High!
crosses of Hybrids wont give you F1's.
You need to make a specific goal for which you wish to fill with this Hybrid. by siting that goal, youll know what to look for, and youll be able to get real awnsers to youre questios.
otherwise youre gonna get a bunch of folks tellin you what THEY think sounds good, or askin you , wtf? lol..
you give good example of what youre wanting to do, but not what for..

What example do you have to compare these 'g13' phenos against?
unless you have a G13 cut, or have extensively worked G13 Hybrids, and can pick it out from observation.... yer likely run into a 'desirable pheno' that is allready unstable combination, or unable to increase uniformity for a given trait inits offspring. and thats not saying its even dominant to G13.

Good grows.
peace, bub.

I gotcha Bub...

because its already a hybrid it may look like G13 but not have anything else in common right?

Well lets say i want to work the hybid more. Am i better off just pollinating all the females with all the males ( not the whole plants obviously) and keeping notes . then look for a winner out of those seeds?

Thanks for your response, ive been eyeing your seeds since they got on seedboutique. I like the OG sunshine, hopefully ill make a summer purchase .

bingo.

that would certianly preserve any Diversty you dont upfront see in the seeds you have.
youre offspring may vary alot, but you will be able to select parents from more of the potential variance and see more of what expressions there are

Keep clones from youre original parents, as you may come to find you want to isolate something from that pool.

Exploring Diversity first might help you understand stabelizing for traits better, later on.

right on bro, sunshine is prime, check out PowerHouse fer outdoors too

heya Bub, exactly what is G13 in terms of genetic definition? There's so many reputed "G13s" out there that I'm completely lost as to what it could be. I know the story about its origins, so in theory all the G13s in seed form out there are the result of hybridization at some point, the original reputedly being a cutting. Has it not become an IBL over the years?

High Indigo!
well, Im shure someone along the way, somewhere, may have bred the cut out then began the task of incrossing, down the lines to stability.. or perhaps Bx. weather or not it represents the original cut would all be in the breeders hands.
and I dont know of anyone who has stabelized G13.. personally..
the exact makeup I believe is in the wind. but I could be wrong, Im shure there has been fairly accurate assumptions made, with plenty of experienced cultivators out there.
Im no G13 Guru.
Ghaze is the only G Hybrid Ive got.

Im not huge on mystery strains...lol too much mystery

Peace bub.

i found good f2s a better point to start with selecting parents for breeding as theyre more variable as the f1, you have to grow a larger number of beans though .
