I would imagine pinning down the auto trait isn't the issue so much as tieing it to the other traits you want in the strain consistently.

Agreed..?

My mistake. I was under the impression that taking say a photo, and breeding with an auto. You would need to run 4 Gen to make all the offspring continually carry the auto trait. I'm just recently been into the photo and auto stuff, and really, breeding for real, not just crossing things. My apologies. Still learning.

If you cross a photo with an auto..All resulting seeds will be Pp ...heterozygous..all showing as photoperiod phenotypically..but all will have 1/2 Auto flower genes..The generation after that, the (f2)...25% will be 100% autoflower and will be easily recognized as Autoflower...Take a male and female from f2 generation...those parents will produce 100% Autoflower in the f3 generation

This is exactly what I thought. I always wanted to try and bring a staple photo strain to auto but I can imagine it not being worth the time .

I've got Subcool's Jack the Ripper photo strain...Crossed with my Genesis Auto flower which is 1/2 Jack the Ripper..which equates to 75% JTR in the f1 beans..when I cross these and the f2's are going to be 75% JTR x my Genesis Auto [25% (GSC, GG4, Tangiematic ..polyhybrid)..]
BUT they will be Autoflowers

Saro..totally cool..
These boards are fantastic for sharing knowledge and learning from one another..no egos allowed.
If I can help others..I'm all over it..just shout! ?
Anyone interested in actively breeding cannabis should be reading Gregor Mendel's genetic studies in snow peas..a great start lots of info out there..particularly Punnett squares

My man! None taken. I'm glad you are on the same page my friend. But yes you are correct, that is great material. Though it appears I need to brush up my punnett square reading hahaha. I've also been reading and rereading and rereading Marijuana Botany by Robert Connell Clark. Another GREAT book I reread often is Marijuana Cultivation Reconsidered by Read Spear. Though I hope in v3 he changes the title. I can't stand the word Marijuana. Even before I knew the history on it I never thought it sounded cool or correct in a sentence. Hhaha. But as always it seems here, im glad to meet another with a good attitude. Thank you for that. That is exactly why I am here and why I try to carry myself accordingly. Much love to ya toast!Saro..totally cool..

Ah, I see, due to the easily spotted "autoflower" you can isolate there. Duh. Thanks my brotha. Sometimes it just slides on by me man hahaha.

Good question. What we have observed is this: F1=0% autos, F2 ~25%, F3~50-75%, F4~65-95%, F5~95-100%

How contained are your breeding premises? Are your plants contaminated by other pollen?
Sounds like you are not selectively picking "just the Autos" from f2 to breed with..
If you breed an Autoflowering plant to another Autoflowering plant..your offspring are 100% Autoflower..no photoperiod!
so somewhere along the line you have a gap in your program. (you're integrating incorrect genetics) .autoflowering is not a codominant or incomplete dominant trait.
cheers

I think he meant introducing ruderalis to a photo
Twenty20 Mendocino is a pretty well established breeder, I'd put money on there being no contamination and them having a pretty well designed breeding regime my man!
What I was kind of getting at with my last post is they're probably not breeding auto to auto at the F1 generation because that would just reinforce the Rudy traits from the F0 generation... if you want to basically make an auto of an established photo strain you need to target plants that show both the traits of the target photo and plants that autoflower in each generation. I'd imagine the idea is to keep only the Autoflower trait from Rudy while maintaining as much of the photos traits as possible... cause the rest of what Rudy brings to the table is pretty undesirable
Edit: I'm super stony. Obviously if your breeding with an already well established auto line your not worried about Rudy's bad habits, but even then if your end goal is Trainwreck auto and your starting with an NL auto your goal would be to breed out as much NL as possible
Edit edit: Also there's the whole scenario of open pollination breeding. Also I'm not SUPER knowledgeable about breeding obviously since I've just started chucking so I'm really just spit balling here lol

Hi Frim
Sorry..Not sure what you're saying..
To expand my comments: I understand Adam is breeding ruderalis (autos) with photoperiod.
I'm just trying to explain the outcomes that he will receive..Unfortunately, the outcomes observed indicate that there is a problem somewhere in their program.

Hmmmm . Guess I misunderstood. Sorry

No worries?

Sorry I wasn't more clear. What I am referring to is creating auto strains from photo strains by introducing the auto trait to a pure photo. This is a long process and takes 3-6 generations to completely isolate the auto trait while keeping all of the traits we want from the photo. The nice thing about it is we get plenty of time to continue selective breeding and select the best plant for the following progeny. We like to have 100 females to choose from but were happy if we end up with 50. Most of the time we run regs for the first 2 generations then switch over to reversing females after that. We find the selective breeding process to be much easier with reversed females because we can judge the female characteristics of both parents. Although the process is a little more complicated, once we are only working with females it saves a lot of space and resources.
Cheers
