This year I have grown eight Campari tomato plants from supermarket tomatoes (F2). From these I have selected two plants from which to harvest seeds (flavour, productivity, overall appearance regarding health).

On one of these plants the first truss produced a double truss or double cluster of some 13 tomatoes. It was the only double-truss occurrence.

Question: are double-trusses a trait that can be promoted through selection and, if so, would the seeds saved from the double-trussed fruit be more likely to continue the trait than seeds from "normal-trussed" fruits of the same plant?
