Primosole Mandarin - Hybrid with Satsuma in the parentage which you don't typically see. Seedless, vigorous, productive, though does have a few issues.

China S-9 Satsuma - Supposed to be the best from a group of selections that survived a bad freeze in China. Also a smoother peel than most other satsumas.

Fukumoto Navel - Very early Navel, three to four weeks before Washington.

New Zealand Lemonade - A sweet lemon that is not totally insipid like most types, good acid balance.

Bergamot Sour Orange - The classic sour orange if you want to use citrus oil, a source of the signature flavor in Earl Grey tea. I would think this would be the orange to have if you want to do anything with citrus peel.

Ugli Tangelo - Simply intriguing to me because it is a Tangelo from Jamaica where it yields sweet fruit with excellent flavor. Supposed to be acidic and lacking sweetness in non tropical climates though.
