The Sweet Giant Marconi Hybrid Pepper is bred in Italy, and was an All America Selections winner in 2001 (I think).
'Giant Marconi' is an improved Italian grilling pepper. About 6 to 8 inches long, the tapered green pepper will mature to red on the 30 inch plant. 'Giant Marconi' tastes excellent raw but is best when grilled. It has a memorable sweet, smoky flavor. Also called Italian frying peppers, Italianelles, or cubanels, these long peppers are sweet and tender and have a thin skin. They are usually either sautèed in olive oil stuffed and baked with the stems and seeds intact, as the seeds give the peppers their characteristic flavor and sweet taste.
The plant produces large, tapered fruits that are 8" long x 3" wide and can be picked green or left on the plant a little longer and harvested red. The fruits mature earlier to red than other varieties.
Enjoy this wonderful pepper about 72 days after setting plants out in the garden. Grow in full sun, at least 6 hours of direct sun a day, in soil that is rich in organic matter and well drained. Start seeds indoors 6-8 weeks before your normal planting time, after the chance of all frost.
Sun: Full Sun
Sowing Method: Indoor Sow

I bought one plant from a local nursery in June, and it already had one fruit. It was quite big by the end of July, and the pepper had a taste as described above. If the plant is productive this year, I will buy some additional plants for the next growing season. Since it is labeled a "hybrid" pepper, I am not sure if those can be grown from the seeds from your own plant.
