How Many Strains are Open Pollination Projects?

[Douglas.Curtis]

Does anyone know off hand, approximately?


Open pollination, where multiple males and females are used to create new seed. Strain, in that at least some culling of less desireable plants has been done and fairly predictable in possible phenos.

My understanding is a more diverse gene pool is preserved, allowing greater phenotype isolation and sub strain stabilization opportunities.

In context, I've bred multiple plants, from two different seed lines, which (without question) all display the desired main attribute. Does this make sense or can you explain it better? My goal is to have a rather diverse pool of genetics to work with, the next 10 - 20 years.

Thank You

To me Open Pollination is the key for safeguarding the genetics of our beloved plant.
The genetic diversity must be preserved. We do not want to bottleneck.

I think Chimera's gear is/was from open pollination.
Maybe the breeders best answer this question.

Grrrrr!
Op is for preservation of landraces.
1:1 is for the removal of unwanted genes and the stabilisation/development of a strain
Selfing is for the exploration of the gene pool.

I understand where you're coming from, and... I'm removing a specific set of genes from both strains. Both strains also share a very hardcoded and desirable trait.

To further complicate matters, I'm unable to distinguish which strain is which when growing out the seeds, they're that similar..

Are you growing out an F1 generation?

Open pollination can be deceiving as well. Lets say you buy 20 regular seeds of a strain and plan an open pollination. For all we know the 20 seeds could have came from 1 mother and hold less variation than we thought.

The seeds were from 2 different generations and sources of one strain and a few seeds of another, not quite stable, strain. So, technically F1's.

I'll probably end up doing another round of culling and open pollinating, simply to produce more seeds for further projects. It would also make the second round of removing the main unwanted genes. The first culling ended with less than a third qualifying for crossing. The first run of the resulting seeds had only about 25% getting culled. A significant increase.

So, not a strain then, just a pool of similar genetics which also share a specific trait. Something to supply a lot of candidates, for selfing and further refining.

Got it. ty.

I have another way to preserve our beloved plants.

Hyper poly-hybridization.

Never cross plants that are related, or as far as possible. If everyone did this we would end up with so many plants that are so not closely related, so much diversity.

In my opinion, better than open pollination.

This is my lifelong journey, Ive already started and I am ahead of a lot of people because I move fast, while the mass is still fine tuning the OGs, I have different ideas...

the only "tru" open pollination project that i know of and pretty well documented is loudog 420 cj x sb
you can find all the info in lds

Appreciate the insights and info.

If you desire diversity you don't want to use 2 similar lines.

If you want diversity, acquire different varieties & cross them together then make tons of F2s & begin exploring the various expressions that pop up. If you can, keep your favorite plant(s) for future generations.

I think, however, that most commercial breeders use 1:1 breeding methods. You'll be hard pressed to find anything that's Open Pollinated.

Somebody mentioned Chimera for OP. He used multiple Blueberry pollen sources (not necessarily all males) for his BB Xs. I think the remainder of his released work is all 1:1.

^ The F1 -> F2 step generates diversity, but if the lines already show both wanted diversity and consistently desirable traits, open pollination (of 100s of plants) will preserve that diversity.

The Ancient Skunk #1 at Breeder's Retailer is another line that has significant OP work. Sam could tell us if the batch is from before or after the several generations of selection through progeny testing that led to the final set of Skunk #1 parents. Which remain > 1:1 if I understand correctly.

Thank you, greatly appreciated.
