what is a f1 hybrid

[edward]

and what is backbreeding

 

[docfishwrinkle]

f1=1st generation offspring from cross breeding

back breeding i believe is get back to a certain strain of the 2 cross bred genetics. its my best edumacated guess

Lots of breeding terminology in this Sticky in the Breeding forum, you may want to head over there and do some reading (a lot of reading) if you are getting into breeding:

F1 hybrid is the first cross.

Backbreeding is breeding the cross back to either of the parents.
Like, say I have a pure indica and a pure sativa. If I pollinate one with the other I have a 50% hybrid with neither dominant - except that dominant genes from either side will win out.

Kind of like a comment attributed to Einstein, supposedly Marilyn Monroe suggested that a child from her and him would be an incredible human because the baby would have her beauty and his brains. Except that Einstein turned down the offer speculating that the child could have his beauty and her brains . . . and so the same can apply with plants.

Backbreeding is sometimes called line breeding and dog breeders indulge in this, to the detriment of many of the offspring. I prefer to call it inbreeding.
In plants you get this if you take your F1 and then breed it back to either of the parents.
Lets say your parents are a male sativa and a female indica. Then you get a male hybrid and breed it back to the female parent you'll get an indica-dominant F2 as I understand it. And vice versa a sativa-dominant F2. But by inbreeding you get not only the chance to develop some super-potent plant but also a good chance of a very inferior plant in some way, like for instance all the offspring are hermie or stunted or bright orange or ....

Since my understanding is limited I shall take no offence if anyone cares to correct the above :tokie:

I basically agree except if you backcross you don't get a F2, an F2 is made by an incross of the F1 siblings... by backcrossing you are actually changing the percentages of the possible genotype expressions and as such it creates a whole new strain, while stabilizing the dominate, like traits within the offspring... backcrossing also presents problems by also freeing some of the undesirable like traits, and creating a premature loss of vigor, this is why backcrossing is only recommended to be done once or twice in the strains life time, and really is more of a very advanced technique...

with that said there are many wonderful things that can be accomplished because of backcrossing, namely CUBING, which is an easy way to preserve a pheno in seed form ( if ya wanna know about cubing let me know and I'll post a thread)... All i am saying is that backcrossing gets very complicated

Have at it, sounds interesting!

i personally think i am not ready for the breeding deal yet.i feel i need to concentrate all my efforts on mastering the growing step 1st.to each his own.like Mass. is an very experienced grower and breeder.he did his time and learned from growing.i feel that all the boks in the world can not make you something you are not ready for.experience is the best teacher.but i do notate everything the pros here post about growing,breeding and every other aspect of growing.i like to absorb the different techniques applied by the masters before putting into practice.sure breeding will be fun one day,just not today.i feel i have a lot of different strains to grow and tinker with before opting for the ones to breed,or xbreed.thanks for all the insightful data here.

Perfect!... IMO, that is exactly where 98% of the members are. Not excluding myself.
IMO one should "Master" the art of growing, become intimately familiar with every aspect of the strain/strains that you desire to work with, and "study" genetics, before actual Breeding is undertaken.

Yes please Mass, I find this a fascinating subject.

I don't think some people understand that there's a difference in Breeding and just making seeds.
Anyone can make babies,I had me a scare yesterday!Thank you EPT

Yep, sorry, you're absolutely correct ... blame that danged Oaxaca I was sampling ... F1 + F1 = F2.
I'm going to try backcrossing with my hybrid Mexican-Afghan when it is mature. I've no idea what *** it is. If it is male I will pollinate the Afghan with it and if female I'll pollinate it with the Mexican. Then I'll have to test the offspring to see if any of them are worth keeping. According to my limited knowledge they will be mixed types. My very restricted space will only allow me to try about 6 plants so it's not terribly likely that I will produce the next wonder-strain.

I'd run em down to about F3 or F4 selecting from a batch of 20 or more then take the one that most leans to what i am shooting for then Bx. Gets a lot of the more recessive traits out when you go down a few gens...see if any hidden herm traits or something

One thing i been trying to figure out...is it better to Bx to the original F1 mom or the orig. F1 dad? I know can work both ways depending on what your shooting for hybrid wise. but just meant if trying to stabalize a specific pheno.

 

[slowmo77]

ok so im lost if i cross a f1 female with an f1 male i'll get an f2?

lets say im workin with aruroa indica which is an f1, if i make my own seeds they'll be f2's? if so in what way will they differ from the f1's? will they display more traits of the orginal parents or traits of the F1's?

i hope that makes sense

 

[Mutt]

f1+f1=F2
