poly hybrid breeding help

i have a landrace durban pioson being reversed to dust some poly hybrids.
my question is since the "father" will be very stable landrace p1 will it reduce the crazy ammount of phenotype variations?

anybody have any experience or knowledge they can drop?

It all depends on the traits that your male will pass on some of the traits are more dom than others within the gene pool. You wont really know what will happen until you make the seeds and grow them.

I was hoping the pure sativa durban would make the indica dominant poly stains throw fewer phenotypes
 
Well since you are going to dust a polyhybrid(ridiculous amount of phenos) to a landrace sativa which are known to herm id say you will get a lot of different phenos and watch closely for herms

im not worried about herms right now i have foliar spray that reverses hermies. im just looking to shorten the 100+ day flowering time and keep the durban poison taste but into an indica growing plant. im going to keep the first seed stock but only plant 20 and clone each one and flower the seedlings to find the flowers i am after then ill self that phenotype
 
Yeah you'd get some shorter in flowering and some with different tastes as well. Good luck on that cross I'm sure you'll find gems in there.

Yes.

If one of your parents is an inbred line, this should limit the number of phenos you'd see. . .but only compared to crossing two poly-hybrids.

How many phenos you end up with is going to depend on the genetic stability of what you're crossing it with.

If you cross two different inbred/landrace lines, then at least for the F1 generation, you'll actually see little to no phenotype variation.

On the other hand, if you're crossing your landrace to an unstable hybrid, you may expect to see quite a bit of variation in the offspring.

If you're trying to breed a new line that you want to work with, then your selection should exclude hermie-prone plants, because if it doesn't, your final line will be hermie-prone.

Well, you could do that, but I'm pretty sure there are already Durban x indica F1 lines out there you could just buy (instead of trying to breed your own from scratch).

Also, don't consider this an endorsement, since I've never grown it and have no comment on quality, but Sensi Ceeds version of Durban flowers in only 70 days, and I've heard of others with similar flowering times. So if the goal is to have some Durban ceeds that finish in only 10 weeks, instead of embarking on this breeding project, you might save a lot of time and hassle just buying them off the shelf.

In terms of what you're planning here, selfing your selected plant won't "stabilize" it, it will only create a variety of new phenotypes in its offspring. To truly stabilize this into a new line, you'd need to use your selected plant as a parent for the next generation instead, again repeating selections, and recrossing until you have something stable with the traits you like. Doing this right is a long project, ie figure at least six cycles or two years.

The f1 wont be too bad, you will have some that lean towards father and some that lean towards the mother.
It will be the f2 generation and beyond where you find the real instability.

yeah im in it for the long run. im looking to find some new f1's to work with. i just picked up the rest of the strains i was wanting to work with so i have my gene pool locked in. by 2015 im hoping to have some sort of stable seed stock of a few different strains . im not trying to change the game im just trying to breed my favorite strains together and just going to sort through til i find some that i like and so on and so forth. i had great success with the santa cruz blue dream already i have some wild blueberry widow and blueberry cough i created that have been bx and selfed a few times just to see what would happen. science can only predict it takes alot of time and work to find a winner i have found with these polys anyways. the landrace durban i selfed pretty much locked the strain into fems all he s1's are almost identical

With this type of cross it is a total crap shoot. Could be great! I would though, destroy most all intersex pheno you find and go from there. The reverse spray is a bandaid on a much bigger issue. You will not regret that. If you made s1 grow a load of those find the shortest flowering time and least intersex expression. You will find something great it just may not be exactly what you where looking for.

Not in any way to knock what you did, but for future projects consider that most of the "name" breeders won't breed with feminized genetics, if they can help it.

Now, whether or not its actually true is a different question, but they think starting with feminized parents reduces the eventual vigor of the line bred from them.

Also, you have to be careful about inbreeding the same line too much without a lot of careful selection, because that's how you end up with the cannabis equivalent of these poor saps:

S1s of inbred/landrace strains are SUPPOSED to be nearly identical (to themselves and the parent), and from a simple growers perspective, those are "winners". This is one really good reason why inbred lines are a great choice for small home growers. You know what you're going to get, and you can make ceeds to end up with more of the same.

In terms of polyhybrids, if you start with great parents, and do enough selection (aka "pheno hunting"), you'll probably find at least a few great individual plants. This is effectively what most of the great "clone only" strains are. . .great individual hybrid phenos.

The problem is those plants will themselves be unstable and you may not be able to get consistent ceed versions without a lot of work, or even (in most cases) at all.

well then you have lot of work cut out for you if you read the above post.
The question is what exactly is the goal here?

Yes, the traditional goal of conventional breeding has been to create novel inbred lines of quality, but that's just not how the cannabis "world" is operating right now. The most "celebrated" lines of recent times are unstable hybrids. All these CA kushes fall in that category.

Think about it. . .if you're already working with genetically unstable "clone only" strains and like them, then what's the "problem" if you create another one (by deliberate cross, or even by lucky one) that you love?

No issue at all, if you just want to grow the plants, and maybe pass out the clones.

Its only a problem if you want to create ceeds. . .but not everyone is so interested.

Again, if you want to make STABLE ceeds (ie where plants grown from the ceeds are morely or entirely similar), you have to do selections over many generations to stabilize the genetics. Done right, that's a several year project.

If all you want is to create ceeds where SOME of the offspring have great phenos (ie you're doing what any number of so-called "breeders" are selling), then you can do that in only a few generations.

true, but that just feeding the frenzy if that is ones goal by breeding for more hybrid bullshit. if that his goal is sell more junk... then well what can i say? i mean its all good to take that approach if breeding for ones own supply. but i prefer the traditional goal myself. IBLs and years of work. this f1 bullshit phase wil come to an end eventually... i hope.

i woudlnt give out these genetics for 100k cash money ...... the only seeds im interested in making are for selecting new strains. there is no such thing as an honest seed breeder so fuck all that business. im not riding the hype im creating it.....

there are still some honest breeders out there. just not as honest as they once where or as many, in haveing to keep up with all these hype riding wannabe breeders selling x5 F1 strains and shit. if it where all honest breeders most breeders would really only have like 2-3 strains at a time for sale unless they where BIG scale like mr.nice for example.
