OK, just a breeding question.

I am currently making seeds, between a fairly stable photo strain, that I have developed. She is a cross between "Razorbud", a local Indica variety, and "Blueberry". I have been inbreeding this strain for the past 5 years, trying to get the Blueberry, flavor in an earlier flowering Indica dominate plant. I am down to two distict Phenotypes. One is more Indica Dominate, which is about 3 weeks away from harvest.


and a more Sativa Dominate, which is at least 8 weeks away from harvest.


Here is a picture of the sativa pheno, sandwiched between 2 Indica phenos.




I am wanting to try and make an Autoflowering version of her, as I love this hybrid. This year, I crossed her with an MI 5. I plan on planting the resulting seeds, and take cuttings for breeding purposes, unless I get one that autoflowers. I will be dusting the clones, with pollen from their father. The problem is this. I will be out of MI5 pollen after the first seed from clone run. I do have HBD pollen, available. Since I am trying to keep most of the traits of the original mother, while making an autoflowering version, should I back cross her with pollen from the original photo strain, to reinforce the original characteristics, or should I grow some some more MI5 for a pollen run, and dust the clones with that, or could I get away with using HBD pollen to try and move more toward the autoflower trait.
I am thinking it would be best, to do another MI5 pollen run, and dust with that. Then do a backcross with the original photo strain, when I have some seeds that actually autoflower.
I am hoping someone here can make heads or tails of what I am saying, and has the knowledge to help me out here.

Thanks

From what I Understand When you cross a photo and an auto only a small percant of the F1s will be autoflowering. You have to grow enough of them out to find a male and female that actually auto in the F1 generation. For a 50/50 ratio of Photo.Auto you would wanna cross those two. And The F1s from that cross will show more that will auto roughly half. Then you wanna take the fastest flowering male and female or w.e. pheno your looking for then cross those two together. That way of breeding is to keep and equal amount of genes from both parents.Keep inbreeding the same genration to reinforce the auto trait. Now if you wanna shortcut all of this you can take any F1 genration of your first cross and backcross to an auto BUT then those Offspring will be 75pct of the auto you used and 25pct of the photo. And only half of the F1 will show auto traits. Which ever parent you backcross to your gonna have a higher amount of genes of that parent in the F1 genration. Now if you wanted mostly the photos genes then you have to find an F1 generation that is fully autoing Then backcross to the photo parent and so on Repeat the above process to Dial in the phenos you want hope this helps.

Actually, I really do not expect any of the first run to auto. That is why I am anticipating a back cross to the father. Then I expect to produce a few autoflowering seeds.

If you do that the offspring are gonna be 75pct of the father and 25 pct of the mother 1/4 of the photos genes will be passed on thats all. If you grow enough of the F1s from the first cross you will eventually Find some that do autoflower.
