Crossing question

[STLbudz]

What's up riu had a Q. So I understand to make a great strain you need to start with great parents ! And not water down genetics !. My question is what if I only had 2 packs and got the best male from those 2 packs and used it.then is it possible to find a gem in those f1s even tho the male was not the best available? Then find a better male from the f1s and keep backcrossing to really get down what I want ? Or do I HAVE to start with the best male period ?

Ps :I know to staple down what you want takes a lot of time and hunting

if you only had 2 packs (ill assume each pack has about 12 seeds and F1) and you took a male and female then crossed them the resulting progeny would be F2 and probably not very similar to the parents at all. if you get enough seeds though you may have a good chance of finding something nice in the F2 if you pop enough of them.

backcrossing will not get you what you want, epecially if your backcrossing to an inferior plant, thats counter intuitive all youd be doing is increasing the likelihood of the progeny having inferior plants.

why do you need a male so bad? if your just trying to make an F1 cross why not find 2 nice females and femenize 1?

what would be the goal in finding this male for this cross?

Hey bro thanx for reply , so how would you get a certain type of terp or characteristic,?wouldn't you need to cross it back to bring it out ? Ok so I have a blue cookies (blueberryXgsc) love the strain but looking to kick a lil more blueberry funk looking to cross that to a few packs of blue alien (pre99.lemonhoko.blueberrryXalienkush)36seeds total . Or blue bubba(hazeman)40 seeds . I'm tryna get a more funkier and maybe a bit more sweeter terps, just want to learn n have fun with it

Hey bro thanx for reply , so how would you get a certain type of terp to come out, wouldn't you need to cross it back to bring it out ? Ok so I have a blue cookies (blueberryXgsc) love the strain but looking to kick a lil more blueberry funk, looking to cross that to a few packs of blue alien (pre99.lemonhoko.blueberrryXalienkush)36seeds total .

1)Q- how would you get a certain terp to come out?

A-It really depends what the seeds are for, commercial use? personal use? selling seeds? selling bud?

are you looking to make a new strain? that would require a lot of time and commitment, if you just wanted to make a cross and sort through the F1 for a nice clone only, that isnt considered "making a strain" but would probably be your best bet at finding what your after with the least amount of time and work invested and honestly this is the route I would suggest for you.

if you actually wanted to devote the time, space and energy required to create a new seed strain though
there are a few ways you can go about it but the easiest method would be to inbreed till the traits you desire are fixed. This approach is a lot easier if your using already inbred lines and crossing them to each other rather than using polyhybrids like the Blue Cookies which is probably ridiculously unstable since its already a cross of a cross of a cross of a cross but if you wanted to inbreed those crosses you have ( blue cookies, blue alien, blue bubba)for 3ish generations with adequate selective pressure towards your desired phenos and then crossed them down the line I think that would also give you some really nice results.

Backcrossing isnt really useful when dealing with an F1 unless your goal is to produce seeds that have a high ratio of plants similar to the backcrossed plant without adding any degree of stability (do a full sib cross of the BX plants and youll see huge variation). the problem is because an F1 plant will undoubtedly be heterozygous for most genes and so you can never fix any traits if you keep going back and crossing plants with homozygous genes for desired traits to one with heterozygous genes for it.

Backcrossing is a really good tool for incorporating new or novel traits from unrelated lines into an inbred line thats already highly stable.

I bet if you just inbred the blue cookies you could achieve the same goal.



sorry if my explanation is a little rushed, im kinda busy at the moment but if u have anymore questions just let me know and im happy to clarify I love helping out other breeders and potential breeders too

@bf80255 right in man !! Thanx for reply .and no makes sense . I really appreciate your time !! I know I hate to give long detailed replies . So for that thanks a lot ! Yeah I just want to have fun with it and I've spent 5k in seed this year and have become a hoarder . I think I rather spend my time and money on my own projects and pheno hunt for my own things . Of course I will still hoard those gems lol but I rather make my own car model then just buy someone elses and plus I get to learn in the process ! Nothing beats knowledge !!! I also have a wifi43 cut plus 5 packs archive face on fire (wifi43XfaceoffOg) 1 more question if I were to find a stud in the wifi43 X faceoff n sexed it to my wifi43 would that be a wifi43 bx?

not a problem man, I love talkin shop when it comes to breeding.
Oh yeah I toally get that, theres something really special about selecting, shaping and molding a line, very rewarding.
hahaha im the same way! hoarders!!!!

Technically.....yes.
but practically... No..
a backcross is only really useful if the original plant being backcrossed to has homozygous gene pairings for its desirable traits. So your best bet would be to first find an elite mom from a good IBL if your interested in backcrossing. otherwise inbreeding again, would be the better option.

The wifi43 is a poly of 2 polys so it will undoubtedly be heterozygous for most gene pairs and thus recurrent hybridization would not lend to any added stability in the line.

I posted some stuff on backcrossing in this thread if you wanted to read that part I think itd be pretty insightful.

Read the hardy Weinberg law of equilibrium.. Fairly easy to understand and there's graphs to help.. Its basic but It should help you
