3 or 4 plants should be enough. Since all should be uniform (if all true F1). If they look like the female parent, you might have not have removed the anthers soon enough.
There have been times when I have only gotten 1 or 2 seeds from a cross. I grow them, and they are usually F1, and you really don't need more than 1 plant (in theory).

Now, I have a question on how many seeds of F1 I need to plant next year to see if the cross is successful?
