Their response:
Our explanation is in that article. Hope you can understand, I can't say it better than Colin explains it there :)
The article that was posted twice. R1 is mentioned but not explained so...

For example:
Mandarin Cookies R1 (V1) = Forum Cut Cookies x Mandarin Sunset
Mandarin Cookies V2 = ETHOS Cookies x Mandarin Sunset (Second Version of Mandarin Cookies)

>> Leaves a void with only the F1 system. And very rare to properly use the term F1 in modern cannabis

To be honest, its not important. If your wanting to know how to breed specific traits the breeders bible has more than enough info. Im closing this thread

You quoted, i was gone, you brought me back...cuz ihad to reply. Now you use a 60page study to attack me then say R1s arent a thing?
No one's attacking you, and if you look at my post, I offered the text to provide you with additional insight. I did quote you to provide context to me reply. You chose to come back, I didn't bring you. If I had that much control over you, I would be your puppet master; be responsible for your own actions.

Why would you close the thread? Lol
We aren’t allowed to continue a discussion that had minimal issues or attacks?

Some of us do not consider Ethos the authority on cannabis breeding terminology. It's just something they made up. Who are they? What qualifies them to just "invent" R1 as a classification?
I don’t think anyone said they were and I think who came up with it is regardless of the fact it does make sense as a classification along with s, f and bx as far as being able to know some things about the strain just by the classification..

I’m not a huge ethos fan by any means, I know I only have freebies banks have sent out from them but I still think it’s a good thing not bad when it comes to classifying a breeding program

Hey, if Ethos wants to use it in their own breeding system for better/easier documentation purposes, all the power to them.

However if you find yourself in a conversation with a horticulturist, discussing breeding, and you start throwing out terms like R1 and V1, don't be surprised when you get funny looks from said horticulturist.

Interesting thread. It reminds me of music theory discussions with the specifics and nomenclature differences among different people.

Where does the term "Hybrid" come into play in all of this?
Heterosis is quantified on an individual or population basis as the difference in the performance of the hybrid relative to the average of the inbred parents (termed the mid-parent value). For quantitative genetic analysis, the deviation of the hybrid relative to the mid-parent is the relevant value

Average heterosis: It is the heterosis where F1 is superior to mid parent value. In otherwords superior to average of two parents.

The general formula for calculating percent heterosis is given below: crossbred avg. - purebred avg. % heterosis = x 100 purebred avg.

Now for the gory part. A population must be considered homozygous before new genes can change the population to the point heterosis breaks a level and the term hybrid can be used. If it wasn't homozygous, it was already heterozygous...ergo still a hybrid itself. I didnt forget about you...just went by so fast.

So is the Cannabis community using the term hybrid more for strain differences rather than actual plant differences? Reason I'm asking is somebody mentioned that Sativa and Indica are basically both Cannabis Sativa. If I'm thinking this out correctly, an Auto flower, with the introduction of a Ruderalis, would be a truer hybrid "type" than the hybrid "strains".
