Maybe this will help.

FWIW, seeds are apparently used primarily to grow grafting stock. You may have better luck obtaining named seedlings (specific cultivars) although it appears that not many named varieties are typically grown here in the US compared to Asia.

Here is a link that might be useful: everything you wanted to know about loquats...:-)

the answer is simple loquat seeds are all hybrids like other fruit tree seeds.

so where can I buy them?

hardeng, where in 9 FL are you? I'm asking b/c 14 mos. ago we moved from Orange Park (s. of Jax) to Houston & left behind a front-yard 25' loquat that gave TONS of delicious fruit and 200+ seedlings/yr. (I wouldn't climb a ladder to pick fruit.) If the tree is still there, I think if you knock on the door and ask to dig up seedlings (they should be getting fairly good sized by now) the curent homeowners would let you. The fruit was DELICIOUS. If you live anywhere near O.P. I can e-mail you the address. Pat (a former 9 yr. Clay Co. FL MG.)

hardeng,

Thank you all for the info. Drewsmaga, I very much appreciate the offer, but as I've been told that the fruits do not grow true from seeds, what I guess I need to know is how to graft or otherwise "create" varieties.
Can anyone give the answer to what I need to do?
Is this similar to making a Pomato plant (Potato+Tomato)?
I just purchased a plant that has a Lemon Tree and Lime Tree grafted together, but they both produce their own individual fruit, so the concept of grafting for a different taste kind of left me confused.
