I literally planted an F1 Sungold tomato a few years back between a Brandywine and a yellow currant. The original Sungold produced a super sweet 1 1/4 inch fruit in clusters of 10 to 12 fruits and boy did it produce a massive quantity of tomatoes. The hybridized crop the following year produced even more fruit in the 3/4" to 1" range with clusters of up to 20 tomatoes. It was very sweet with a tang of acidity. Almost like a lemon drop . 2024 will be my 2nd year to see if the seed is stabilized. I really think I have something really good
