Clementines and Tangelos will easily produce hybrids. Just keep in mind, the mother is one of the parents, so the fruit should have many of the characteristics of the mother.

Other than the varieties already mentioned, King Mandarin and Temple Tangor are mono embryonic, and do not come true from seed. - (Millet 946-)

Thank you Skeeter and Millet. I think my best bet will be to buy a Clementine tree, they are the easiest to find here. I've also seen Citron Etrog and Citron Buddha's hand for sale here. Wikipedia states all Citrons are monoembryonic, is this true from your experiences?

Typical Buddha's Hand doesn't form any seeds. I'm not sure, but I think Etrog is monoembryonic.

Actually, most Tangelos come true from seed, so they do not produce hybrids. - Millet (946-)

At some point in the past I tried to come up with a list of monoembryonic citrus varieties using information from many different sources. Here is the list of varieties I came up with. I am sure there are others but I have not seen others documented.

Pummelo
Citron
Kumquat
Ichang Papeda
Bearss lime
Meyer lemon
Clementine mandarin
Ellendale mandarin
Encore mandarin
Fortune mandarin
Fremont mandarin (Half?)
Kincy mandarin
Kishiu mandarin
Lee mandarin
Wilking mandarin
Clement tangelo
Ugli tangelo
Temple tangor
Umatilla tangor
New Zeland grapefruit (Poorman orange)
Wheeney grapefruit
Chironja grapefruit
Sukega grapefruit
Bergamot
Citrus micrantha
Desert Lime (Eremocitrus Glauca)
Ponderosa lemon (very low poly)
Sweet lemon (very low poly)
King mandarin (low poly)

The Tangelo I was thinking about is the Minneola Tangelo--it probably falls into the category of low-poly as it will set fruit without pollination, but fruit set is significantly improved with a pollinizer.

Thank you for the list jrb, very useful.

I pollinated 4 kumquat reale flowers in total with pomelo pollen. All set fruit then recently the tree was ill and lost alot of leaves and fruitlets. No idea why, it seems ok now. Now only 1 cross-pollinated fruitlet remains, and doesn't appear to be growing, it's the size of a pea. It's been exactly 3 months now since the flower was pollinated, can anyone tell me how long it's supposed to take kumquats in general to mature to ripening?

Update on the cross-pollinated fruitlet. It hasn't grown at all, still the size of a pea, whereas the surrounding self-pollinated fruitlets are much bigger - about the size of a small marble. All were pollinated at the same time exactly 5 months ago. Is the lack of growth a sign that the cross-pollinated fruitlet will fail?

Maybe it's taking forever to decide what kind of genetic traits the seed will inherit, because it's such a mindblowing cross

Alright lol, Yeah I explored this forum thoroughly before I ever got my membership approved.

By the way, I just had my first Pummelo ever. It was from the supermarket, but it was AMAZING. It smells like flowers and tastes like fruit punch! lol

I'm guessing its Hirado Buntan maybe. Green skin and pink pulp.

John Panzarella has 15 gallon one for sale I almost picked up last week, hmm. Maybe I'll take a trip down there monday : )

I know Changshou is strongly polyembryonic. Does anyone know about Meiwa?
