crossing autoflower with regular

what happens if you cross an auto with a regular (non-auto) strain?-

You can’t clone autos. Because they flower on how old they are instead of switching to “flower” if you clones a auto, the clone with flower the same time resulting in waste of time.

If you cross, the % of auto gene goes down. You can do it. But there’s a chance it won’t auto flower

Photo x auto crosses supposedly start and finish flowering a little earlier than the photo parent, and will likely be somewhat larger than the auto parent. Supposedly yes, they will flower with a little more light than the pure photo parent would.

I can’t answer the question about whether or not they’ll flower specifically under 16 hours of light. I just don’t know the answer though I’m speculating that its possible and might depend on exactly which photo and auto you’ve crossed.

The reason you haven’t is that auto plants can’t be maintained in “mother” form to generate clones.
Yes, you can take a cutting from an auto and root it, but the clone will mature just as fast as the mother, and when the mother is done, so will the clone be. There is no advantage to taking such a cutting; the net effect is just to reduce your overall yield without maintaining the genetics you’re after.

Well, depending on what you’re trying to accomplish, it can take that many crosses to create a “pure” autoflowering version of a standard photoperiod plant, though in practice, very few breeders really go that far, and you can get most of the way there in quite a few generations sooner than that. I don’t think this is what the original poster was asking about, though.

I don’t believe this is correct.

Since the most common autoflower gene is recessive, it requires TWO copies (one from each parent) for any offspring plant to be autoflowering.

If you cross an auto with a photoperiod plant, each of the offspring will only carry ONE copy of the autoflowering gene (from the auto parent) and you would expect NONE of these F1 offspring to be autos.

If you then crossed two of these F1 plants to create an F2 generation, you would expect ONE QUARTER of the ensuing F2 generation to be autoflowering.

And if you then crossed two AUTOFLOWERING F3s (or an autoflower F3 with any other auto) you’d expect all of those offspring (or nearly all) to be autoflowering.

Just curious if the plant would flower under 16 hrs. of light, be larger than the auto parent, or what one might "generally" expect from this cross? Another…

In your project what you would need to do is first make your cross. If you don’t want to pollenate an entire plant it is easily accomplished. I collect pollen by tying a small white paper bag around the branch of my male plant. I leave it on for 1 or 2 days and occasionally give the plant a good shake. As the flowers open you will collect pollen in this bag. I then simply remove the bag and carefully tie it over a top branch of the female that I wish to pollenate. Again I leave it on a couple of days, ( you know to give them privacy!) giving the branch a good shake occasionally.
After removing the bag let Mother Nature do her thing and you will have your controlled crossed seeds. Now comes the tricky part.

The main thing with any breeding program is to maintain focus on the characteristic that you are breeding for. It is so easy to get off track as you stumble upon this plant or that which has a characteristic that you like. But, for the sake of this discussion we will talk strictly about auto flowering traits.
Hey Wahtoogee! I am making my own Auto seed this summer and you can too. I am crossing two auto varieties but you could conceivably do it with a regular flower variety, in fact I am helping a friend try to create an Auto Grand Daddy Purple.

And it could have autoflower male seeds?
Grow out the seed. Now as the seed grows notice and mark the most vigorous growers. In the case of Auto flowers especially pay attention to the robustness of the root growth. It seems to me to be one of the characteristics of auto flowers. Grow the plants through their life cycles.
I tie small pieces of different colored yarn onto the plants in the order that they flower. For example blue for the earliest flowering females, maybe red for the earliest flowering males, etc. I also use different colors for the next batch that begins flowering. As you go cull out any weak or late flowering plants.
Now by crossing the earliest flowering plants you can some what begin to stabilize this trait in your new line. You will now see why I say to maintain focus. Because you will invariably find plants that are really smelly, or colorful or frosty it’s easy to get side tracked. You can always increase these traits later in your line. But now you are just looking for auto flowering characteristics. I do always keep in mind the general vigor of any plant. So if I have 2 blue yarn plants I will make my next cross with the most vigorous healthy grower.
My guess is a “grab bag”? Some male or female regular, some will autoflower, some will not?
Thanks.. “Just wondering”.
Title says it. What would happen if you had a regular male plant pollinate an Autoflower?

You can now see why breeders can earn their money IF they do the job right. There are some really good ones out there. Unfortunately there are also some that are not so good. I have been breeding my own weed for years with varying levels of success. But all in all it is a very rewarding hobby and for me a lot of fun. Regardless of if it is an Auto Flower that you are trying to produce or a new batch of that Wahtoogee Wonder Weed I think it’s cool to know that no one else on the planet has exactly what you are rolling up! Have fun! If I can be of further help just let me know. Until then I’ll be just uptheholler!

Cannabis normally requires long dark periods to trigger flowering, but there are varieties that will flower regardless of the lighting conditions. These are known as autoflowering varieties. Not all cannabis traits are as simple to explain, which is part of what makes autoflowering a good example for beginning breeders to start with.

Cannabis is a diploid, in other words, it gets one chromosome from the pollen of the father, and one from the ovum of the mother. This means it will have two genes (one from each chromosome strand), each of which can be one of two alleles, either autoflowering or not.
A practical experiment can illustrate the above:

It is important to note that because of dominance there is no way to visually tell the difference between PP, pP and Pp. They will all be photodependant—only the recessive pp from this generation can be easily identified as true breeding.
Even if a breeder isn’t fond of autoflowering varieties, the process and learning experience of working with them can help expand their understanding of how genetic traits work in a way that is easy to see and will give tangible results and feedback.
Of importance to breeders, both experienced and aspiring, autoflowering is an easily observable simple Mendelian recessive trait. It is generally quick and easy to determine if a given adolescent plant is autoflowering or standard just by keeping it in short (or non-existent) dark periods for a few weeks. If the plant stays in growth, it is standard. If it flowers it is autoflowering.
While technically there are four combinations possible, effectively it doesn’t make much difference because all of the combinations result in PP (true breeding for photodependancy). This is why breeding a standard cannabis plant with another standard cannabis plant will result in standard cannabis offspring. The same is true of autoflowering.
Gregor Mendel, a friar who conducted experiments with pea plants in the mid-1800s, tracked traits such as seed shape and flower color, and developed basic rules for understanding genetic inheritance such as the concept of dominant and recessive traits.

  • The hybrid father will contribute either his P or p.
  • The hybrid mother will contribute either her P or p.
  • The resulting combinations are either PP, Pp, pP or pp.
  • The PP will be true breeding for photodependancy, and will show photodependancy.
  • The Pp and pP will be heterogeneous for photodependancy but will still show photodependancy because of dominance.
  • The pp will be true breeding for autoflowering, and will show autoflowering.

When it comes to breeding cannabis, autoflowering is one of the most basic types of genetic traits of the plant.
