Mike put it somewhere on the chile-heads web pages, though I don't know
exactly where. All I know is where the original is, and here is a copy of
it.

KEY:
NG = F1 hybrids germinate normally
EC = F1 hybrids raised by embryo culture
IV = fruits/seeds set, but F1 seeds inviable
PF = F1 hybrids partially fertile
HF = F1 hybrids highly fertile
- = no data, or perhaps "does not cross" (original publication does not specify)
