R1 vs F1

[highatollah]

How do R1 seeds compare to F1 seeds? Are they of equal quality? I have no experience with seeds, only clones.

Thanks for all replies.

F1 comes from 2 unrelated plants, one is male and the other is female. Could be the same strain but different lineage. Most common F1 though, are 2 different strains.

R1 comes from 2 related female (sisters), where one female is reversed to pollinate the other female.

Obviously, F1 is a better seed, genetically superior and possibly have heterosis properties.

R1 is pretty much the same as S1. While S1 comes from one plant, R1 comes from 2 plants.

Thanks for the response. I understand all that but my question is will the R1 be inferior to the F1 seed? I see seeds for sale for an R1 seed with pictures of the F1. If I buy an R1 seed is it going to be inherently inferior to the F1 pics I see on instagram?

Thanks.

All pics are suspect ...the seeds themselves may or may not be a representative of the parents...even f1 may not reflect the original clones

My mistake I assumed heterosis was a reference to sexuality. Was not in my vocabulary.

You are wrong..... R1 is a cross of two un-related feminized plants where one was reversed to pollinate the other. S1 (selfing) results from reversing and pollinating the same plant, whether just a branch or a cutting (clone) of itself.

R1: First generation cross of two unlike parents (same as F1) but indicates the pollen donor was female (feminized).

So an R1 is closer to an F1 than an S1.

7 year old thread. There's a good chance you dont get a response.

I think the term R1 has been used for both related and unrelated parents, and there isn't exactly a standardized nomenclature in cannabis breeding.

If two sisters are bred together, then they are more like a F2

If two unrelated female plants are bred together, then they are more like a F1 (or more accurately in most cases, a poly-hybrid.)

When you cross two sisters, R2 would be the appropriate notation. And if you self a S1, you get a S2.

I think a clearer definition of the "R" is that it conforms to the same rules as "F" generations, but indicates a female-only line. That said, I've never seen even a R3, so there could be issues inbreeding within a female-only population. Would be interesting to read something concrete about that.

Most everything available today is poly-hybrid.....
