When i was able to bring in tomato seed in 10+ years ago I got some seed through Tomatoville a tomato called Hoy, it was huge,I ended up with fruit of close to one kg or 2.3 pounds, not sure what 12 ounces is but does this come close.
99% of growing big tomatoes is starting with genetics that can produce large fruit. Mortgage Lifter Red, Mortgage Lifter Radiator Charlie strain, Mortgage Lifter Estler's, Omar's Lebanese, and Zogola are a few examples of varieties that can throw 2+ pounders.
I'm going to grow the biggest tomato you've ever seen this year!
Best pull your seed out and get started. I have one tray going already and about to start a few more.
No word on how that all went! I was looking up some "large" beefsteak tomatoes on Tatiana's tonight and sort of gave up, that site is too huge to cope with in just a couple of sittings. What varieties did you plant and how did they do?
I was wondering about that too. When I was a kid we grew giant tomatoes. I pretty sure they were brandywine. I remember they were pink color. Years later the brandywine I grew didn't compare at all. I do get an occasional very large tomato from various kinds but seems like if it makes really big tomatoes it only makes a few. I'd rather have lots of smaller ones.
that is one complicated tomato! what variety was it?
a beefsteak variety that we've used for years. i suspected the greenhouse got some wrong seeds or something happened somewhere but perhaps it was the heat that season. a lot of tomatoes we grew had a lot of those inclusions in them. this past season we had some tomatoes which had a little of that going on but nothing like that one.
