Why are my seeds different sizes

I've been cutting a few plants from an accidental breeding project. All the seeds from the crosses I've made have been fairly consistent in size. But this one plant which was a Coljam had seeds that ranged from a size like yellow millet to a white wheat berries. All the plants were pollinated by the same 1 male too. Why did the plant produce seeds like this? Does seed size play a big role in plant genetics?

different womb sizes

Did you pollinate the female more than once? When I make crosses I typically pollinate them a couple times a week or so apart. Sometimes the seeds look different and I've always just assumed it was from that. A recent run had obvious dark and light seeds all viable. The plant was pollinated twice with the same pollen. I had no other males developed enough to produce pollen at the time and hadn't for awhile either so no chance of stray pollen. Seed size doesn't mean much at all.

I’ve had plenty of brick weed that had everything from dark brown basketball seeds to immature greenies easily crushed. Probably from multiple pollinations.

If you don't like the smaller ones you can give them to me

Sounds good boss, I have more than enough seeds and not enough testers. Although I'm a home grower and didnt really expect this many seeds. I've got quite a few peach hashplant from seed pollinated with coljam. Peach Jam

Sounds good to me check your msgs

So This is a great question that I have no real answer to, just theories. Lots of old breeders will swear that good drug varieties have smaller seeds. I'm not so sure about that. It seems to me like the seeds are smaller with indoor bred vs outdoor. I've got lots of seeds that have been bred for generations indoor and they always are small, while the outdoor seeds seem larger. Back in the early 90's we used to get a lot of outdoor bud from Oklahoma and Arkansas. It was mostly skunk and Afghani. From what I could understand they were grown and bred outdoor for 20-25 years. The weed was fire and had "popcorn" seeds. Some was totally seedless, but most just had a few seeds. Occasionally the bud would be loaded with seeds and was 5 to 10 bucks an once cheaper. The amount of seeds never mattered. It always had the huge popcorn seeds. The mexican bud we used to get also seemed to have large seeds. So all in all to me it seems outdoor tends to be larger in general and indoor seeds are smaller. Regardless, if you have a plant that's getting continually pollinated seeds will be at different stages of development. That's just my 2 cents.

Seed size is irrelevant to anything. It matters not.

When your 10 inches it just looks that way lmao
