No I am not planning to go commercial, so I probably will not have to do
time for plant patent infringement.

What attracts me to the Tuxedo is smut resistance in a sweet corn that it
is not white, does have good flavor, good tip cover and a good sized ear.

I was planning to save maybe 3 ears out of the approximately 100 plants in
my garden this year. It is too late to do another variety along with it.
If I understand single seed descent.. three ears is not it. Now If the
tuxedo develops any smut this year.. I am not saving a single seed. (and I
will be saved from a life of crime)

I have been trying to find other smut resistant non-white, tasty sweet corn
varieties. So far I have found these but I am not sure I can actually get
the seed.

Sweet Rhythm (HMX 3354BES) - Breeder: T.Natti. Vendor: Harris Moran.
Characteristics: 70 day maturity, bicolor, dark green attractive husk, 7.5"
ears, 16-18 rows, very good eating quality, has se and shrunken-2 endosperm
on the ear, good seedling vigor. Resistance: tolerance to stewarts wilt,
common smut. Similar: Seneca Brave.

Sweet Symphony (HMX2349BES) - Breeder: T.Natti. Vendor: Harris Moran.
Characteristics: 75 day maturity, bicolor, good husk cover, fair flag
leaves, light green color, 7-7.5" ears, good tip fill, sometimes a small
tassel tip, good sweetness and flavor with se and shrunken-2 kernels.
Resistance: tolerance to common smut, stewarts wilt. Similar: Harmony.

The Tuxedo is in England.

If I would cross next year, It would be a non-white good sized tasty sweet
corn without the smut resistance that I am hoping to retain. Or I could
just order corn seed from England.

Corn breeders typically use elite inbreds to make their hybrid seed. They
are also very protective of their germplasm. I'd be more worried about
legal ramifications of saving the seed than inbreeding depression in the
early generations. Assuming that this is not a concern, in the F2 or F3
generation where you would be initially growing, you will see a variety of
phenotypes, but not inbreeding depression yet. If you took care to save a
population of seed and especially if you brought in another germplasm into
the mix, you could save a pool of seed that preserves the characteristics
you like without having a huge yield penalty. I assume you don't plan to
grow this corn for commercial purposes. If not, a small yield penalty even
many generations down the road would likely not be noticeable to a home

Just don't take it through single seed descent. Then you will definitely
see inbreeding depression in later generations.
