If your male was an auto, you will have auto flowering seeds, but they will be regular seeds, not fems.
If your male was a photoperiod plant, you could have a what they call "early harvest or fast flowering/versions" of photoperiod seeds. The slight infusion of auto flowering genetics into photoperiod plants results in photoperiod plants that flower faster and a bit earlier than normal photoperiod plants of the same strain.
This is all "in theory".
However, with my own experimental crosses between photos and autos, this has given mixed results, at least in the first generation of plants.
Some plants were autos, some were photos and some were fast/early flowering types. Due to the variable results, I have not continued further experiments due to space and time limitations, but inbreeding of the various types might stabilize traits for either being autos, photos or early/fast versions.
Again, due to the great variation in the offspring, crossing autos and photos is not something I would recommend to all but the keenest of researchers.
You can certainly grow your home bred seeds, just be aware they are "regular" seeds with a 50/50 chance of being either male or female and they will definitely not be "feminised" seeds.
They will also have a big variation of genotypes, autos, photos and some being something in between, assuming they are the result of crossing photos and autos.
If both parents were autos, then you will have "regular" auto seeds, with the same 50/50 chance of being either male or female.
Hope this helps,.....
