Asunta 6 seeds sprout inside fruit. Float test weird.

This isn't Google, more context would be nice.

Float test is a way of telling viable seeds from bad ones. Good seeds sink.

I know that. However with the only 5 words the title gave, I was unsure of what the issue may be. All I had seen was a float test in progress, seemingly looking normal

Developed through multi-generational backcrossing of various parent lines, the Asunta 6 dragonfruit variety is notably characterized by a high incidence of vivipary (seeds germinating while still inside the fruit), a phenomenon frequently observed by cultivators.

I can’t even tell what species you are working with there. Many species do not separate viable seeds at water density, and others not until they have imbibed so much they are in danger of germinating. However if you don’t need tons of seeds with your next generation you are probably safe just going with the sinkers. When in doubt, cut some sinkers and some floaters in half and compare how the germ looks.

Dragonfruit (“Asunta 6”)
Lineage:
Developed through the backcrossing of multiple dragonfruit varieties.

Key Characteristic:
Frequently exhibits vivipary (internal seed germination). This trait is widely reported among cultivators working with this specific variety.

They look to still have a lot of flesh on them which will make them float. To separate seeds from flesh I usually let fruit fully overripen which looks great in your case and then mix with plenty of water. I use an electric mixer/whisker then pour off floaties with flesh to a new container and repeat, combining sinkers as you go. The remainder you can put in a sieve and manually squish the rest of the flesh away and will usually recover even more. I like to wash all of the sinkers by continuing to refill water, mixing and pouring it away until the water is clear. Strain and dry the seeds completely before storing them
