When estimating the F1 fruit size in a cross, I have used the following formula which has be fairly reliable, not exact because growing conditions can strongly influence fruit size contrary to what the genetic potential would give:
The square root of A x B = F1 size. So with yours, I estimated the F1 size will be the square root of 3 to 4 ounces x 8 to 12 ounces or roughly the square root of 24 to 48 ounces, or 5 to 7 ounces more or less. |

Travis - you told me about your fruit size prediction equation a few years ago, and by golly it seems to work pretty well in the F1. All bets are off in succeeding generations where I find mean fruit size more difficult to predict.

Here are the first green fruit of the first cross I have ever made, Fiaschetto di Manduria x Cherokee Chocolate. First two pics are pics of the parent varieties.
