question on genetics

i want to breed my own Auto-flowering plant. one thats acclimatized to warmer climates, and therefor takes longer to flower=bigger harvest. i'll tell you what im thinking about and you can just tell me what you think.

these are the genetics im thinking of working with.
Early wonder skunk= Afghan X thai =AT ..................................... Guatemalan X ruderalis = G-auto
AT X skunk#1= Thai skunk
Thai Skunk X g-auto = early wonder skunk

Aurora Indica = Afghan ..................................... european sativa X european Indica= northern lights.
Afghan X northern lights = Aurora Indica.


the final cross will be 60% sativa 20% indica 20% ruderalis. im thinking i will have to cross it back to EWS to push more of the autoflowering genetics into the plant to stabalize it. but IDK, what do you guys think?

Edit: im trying for a 50% sativa mix with some indica, and ruderalis for the autoflowering genetics......

I sure wish you luck with it. I wish I was a bit better at the breeding myself. I have been working a couple of crosses with a lowryder1 and bagseed plant. Three grows and crosses but not much luck yet with anything. I will keep working it everytime I have room in the rotation to try again though.
I wish you the best of luck and all the fun that comes with doing this, even the ones that don't work out smoke good.
