Autoflower + photosensitive strain = ?

[theintu]

Excuse my noobie question, though what happens if I breed a female Autoflower with a normal photosensitive strain, will it produce photosensitive seeds or autoflowering ones, or neither? Thanks in advance

Nevermind, just found the answer on another thread

But then again, it would be nice if you provided the answer so we don't have to look for it ourselves. ;-)

My guess (and experience) is that you'll end up with a photosensitive strain. You'll have to breed with Ruderalis, before you can mix in a full-auto strain.

No sir cross any photo with any auto and you have an Auto, using Ruderalis would produce a weak Auto, just cross your favorite Auto with your favorite photo and presto - have fun and to breed a good Auto simply use a good Auto Hope that helps

GG, I'm pretty sure it won't work that way. Photo + Auto = super super early photo. There is a lot about recessive gene traits that I don't understand, but bottom line, I believe it takes at least 3 generations of breeding to get a photo into an auto, starting with good auto genes.

Edit: ^I base this on the way Cres has explained his breeding...he makes early outdoor photo crosses for canadian medical patients, and does it using autos and photos.

I am not a pro Auto grower but I am a genetic scientist of sorts and I would like to point out that the Auto trait does appear to be dominant and after crossing for numerous generations with photos the Auto traits are retained. Truth is cross a photo with Auto once and the next generation is Auto , back crossing for 3 generations can of course enhance or perhaps fade the genes. May I also point out that most famous Autos today are not made from Ruderalis but by using Autos that may have only a small amount of ruderalis in them but still retail the Auto trait

I think you are both correct...a photo x auto cross will eventually yield an auto... phenotype selection and backcrossing may stabilize the auto trait by the fifth generation..(f5)...but,some auto gene selection is not fully utilized when the optimal fruiting and flowering is photoperiod dominant.
the structure ,potency and resistance to disease may have been the primary selection criteria...not whether sex is expressed independent of light hours.

Very diplomatic sir and basically the problem is we are trying to sum up complex matters, one important thing about the backcrossing is the hundreds of plants that should be grown to provide a large enough selection for professional selective breeding and I appreciate that some of the masters here at AFN must get frustrated when they see newbies entering the world of new strain creation, still there are chuckles and AFN does provide the avenue for those with the patience required to learn these arts and we are talking decades I myself have very limited experience of medical and Auto MJ genetics and am here hoping to learn too. Of course people wanting to cross an Auto with a Photo might not get a stable strain but why worry when you have then unlimited seeds and can eat the runts for salad.

I always thought the auto gene was recessive.

absolutely...in trying to isolate a terpene dominance...I bet I've grown out 100 seed from a recent backcross...males and mis-haps aside...that's almost 60 females that have not shown that terpene that the mother had...but,the quest for the linalool dominant pheno goes on....10 more put in to germ today....
good tip on eating the runts....I comsume everything but the roots from my plants in blended smoothies...no wasted cannabinoids.
