Where do you all get your tetraploid seeds?

I found the tiny watermelon seeds. They look fat and healthy to me. Don't know whether they're viable or not. I'm going to grow them and see if they sprout.

For size, the tag to the left is the size of my finger tip.

Does look like at least some of them should germinate.

A little seed of watermelon have less reserv of nutrient for germinate.
She is more sensitive and less vigorous than a big seed if she germinate in a bad conditions?

So I was checking out a new farmers market for a potential new place to sell. I bought a watermelon from a Nepalese guy, got home opened it up and thought it was a seedless. Upon further inspection I found it wasn't seedless, but had miniature seeds, about as many as a average melon would have. The melon was beautiful and sweet and about the size of a sugarbaby. When eating it you cannot tell the is even any seeds in there they are that small.
I remember seeing a tiny seeded melon on 2seeds in a pod website for sale, but assumed the melon itself would be very small so never pursued it. It's called "tiny seeded south American" the pictures on the website look pretty similar to the melon I bought.
These would be great for a "seedless" variety but with seeds that you can select and breed quite easy.
Has anybody had anything to do with this melon?

Still interested in this. Just emailed a professor from North Carolina University to see if he knows any accession numbers.

He was very helpful a month back when I asked about citron melon accessions with non-lobed leaves. I now have seeds for a domestic watermelon mutant that has non-lobed leaves. I believe breeding for non-lobed leaves may be advantageous in temperate climates with short seasons to maximize solar energy capture. Lobed leaves are probably adapted for severe drought conditions (something not experienced on the average farm).

Yea, tiny seeds sounds like something I'd love to have on hand, but overall I'd tend to be more inclined to breed for large seeds.

The professor did not know of any with the ts gene (though historically it is derived from a Sugar Baby mutant).

But he did mention the variety "Jenny" is often used as a seedless watermelon pollinator and has very small seeds.

My Costa Rican Thin Rind watermelon has pretty small seeds, but then again it is a pretty small melon (baseball sized at it's maximum)

This thin rind trait sounds interesting. In my citron- melon project I had a segregate that had extremely thin rind /skin. Unfortunately I had a crop failure when I tried to grow that line out. I have a picture in the citron hybrid thread.

If it is similar,  any chance to obtain some seed?

Not right now. I only got one melon that time so I only have a handful of seed (plus with only one plant, the stuff is REALLY inbred). I'm planning to cross it with Silver Yamato to try and get the diversity back up. After that, who knows.

Premium and Polimax are both said to be super small seeded, here: https://www.nunhems.com/us/en/Varieties/WMW_watermelon.html

It seems they are using small seeded cultivars for pollinizers. Does it mean that pollen doner effects the size of the non viable seeds in the seedless watermelons. A general question.
By looking at seeds in a watermelon can we determine if a cross pollination occured ? I remember saving different colored seeds from two different watermelons of the same variety in one year.

For the first question, I have wondered the same myself. You would think that any tetraploid x diploid would come out as tiny undeveloped seeds regardless of pollen parent and if anything did matter I would think it would just be up the the mother genetics if anything. But it is an interesting practice. Makes one wonder.

As for your second question, yes, at least in some cases. It depends on the heterozygosity vs homozygosity of your original variety or varieties and the seed color of those,  but in some cases you can. I am actually re-doing a watermelon seed genetics picture table for my new website, and I almost have it finished. I'll let you know when I do. Maybe I can finish it today.

The basic dominance pattern in watermelon is more color to less color. Black over dotted black. Any black over brown/tan. Any of those over green or red. Green may or may not be undeveloped brown. Red over white with pink tips.

Apparently there may be three different white seeds. White with black tips may be dominant over brown I think and any others that come after. So basically it is not actually white since it has some black. It is similar to when Darwin crossed two white pigeons and got a blue pigeon. One of the white pigeons had black tail feathers and when crossed it restored the blue color hidden in the pure white pigeons dna.

Would still love to work with this trait. Seems it is already being exploited and commercialized in Japan.

I found a micro seeded watermelon.
It is called Tigrimini f1.
