I have a whole bag of seeds from 1 batch. None seem to be polyploid or triploid. But they all seem to be sterile . Ive grown out of this bag of seeds for the past 10 years and every year i try to pollenate. The plants never take pollen and seed. Tried very many times . Could someone give me insight as to how these seeds became sterile and maybe what caused.

Something here does not compute. The fact that you have a bag of seeds proves the strain is viable. The ability to be able to produce plants from those seeds show that the seeds themselves are not sterile.
Not knowing your methods of pollination make it difficult to answer your question with any confidence of giving you an informed answer.
If you are growing these outdoor it could simply be
wind direction or an abundance of humidity causing your problems.
If you are growing indoor than the only thing I could possibly point to is your methods of pollination.
I have never ran into a strain that produced males that were sterile or females that would not accept pollen so I am at a loss what the cause of your dilemma may be except for methods.

Welcome to OG @Cannaconnoisseur
Maybe get another lad and try the pollun there. Get other pollum(or a gent) and try to pollinate with that one. Might help to narrow down the issue.
In the end, if that one is the only bag also pollinate the external fem with the external pollum the prove its not your method.

Ive heard of it just happening at certain points in some plants line work. I believe bodhi worked his purple unicorn to f5 and it became sterile. Dont know what causes it beyond genetics. I think CSI also talked about a similar issue with Irene Kush s1’s or s2’s
What seeds are you trying to pollinate?

Unless it’s literally got 0 hairs I’m sure you can get it to take something might just be a picky one as for the ones that are totally sterile I have heard it said selfing and too much inbreeding with bad choices can do it

Why? I have no idea. But here’s my similar story.
I had gotten some choc diesel pollen from @AzSeaindooin420 and pollinated a Dracula that was pretty nice. Drac was dusted pretty good and I got 6 seeds…only 3 which were viable. Grew those out, 2 girls and a boy and made F2’s. I ended up again with only a few seeds. My only form of control in this is that I used that same Choc diesel pollen on numerous other cultivars with no issues at all. So I associate the lack of seeds to the drac mom being resistant or something and I have a small collection of F2 and Bx’s but after putting in the work and getting my ass kicked I moved on to other things.
Maybe not so insightful, not sure why or how but relatable for sure.

Seems you have got a true sinsemilla there!!!
As people said, hybrids can be sterile. Any ideia what’s the parental generation was?

Gene regulators on the stigma are analogous to keyholes that only accept certain specific pollen types for pollination. Sometimes during the breeding process, the genes that regulate stigma growth can become altered so that the stigma can no longer bind to the available pollen types…the stigma have no homologous chromosomes for mitotic pairing to occur… basically, the pollen does not fit correctly in the “keyholes” which instantiate fertilization, so the plant appears sterile. This is usually the case with tri-, penta-, and septaploids. You can’t always visually distinguish the genetic makeup of a plant, the detection of polyploidy most of the time requires lab tests.

These seeds were def made from selfing

The true og from elemental seeds . They are fem and were made by selfing

The pollen that i were trying to use is actually first gen from a strain i bred
Cap junky and 88g13hp are two known for it that come to mind. Some people are having the issue making fem crosses with newer strains.if it were me i’d cross a nice male of something else with it.

I threw enough Mazar pollen on a mac1 to get thousands of seeds of a normal plant the size that it was , I got about twenty mutant white unviable seeds and 4 good ones. Some strains are known to be difficult , may or may not be a good thing.

Sounds like some breeding depression from the selfing,coupled with you mentioning 1st gen pollen,read old. Could that be non viable? How long did you store it. Did you get seeds that wont grow , or no seeds at all.

No seeds at all and frest pollen. Been growing same batch of seeds from both the fem line and the line i use pollen from

aha, they are fems …
and (f.e.) csi → fems and uses (mostly) no males
could that be a result of leaving out male
side of chromosomes for “a while”? 
( i have no real clue, but somehow i really feel
more secure about making seeds with regs 
)

How do we know for sure that its not a triploide?
Inbreeding depression occurs only when an individual has two copies of the same recessive gene. This is both a “danger” that can occur with selfed-crosses, AND can also be a way to weed out the unwanted recessive genes by focusing on selections of plants that only contain the desired genes…which requires genetic testing or multiple generations of observing the results of large populations of seeds being grown out and observed for the unwanted traits.

Why i favor regs🙂

So the recessive trait remains hidden until someone down the line has to deal with their disastrous results? I prefer to test thoroughly
