Someday I need to sort out all of the literature and see if there is a final answer on what happens with figs.
In my limited experience, few of my seedlings have been Smyrna or San Pedro types. OI am not at all sure whether caprifigs (male) are common, Sp and Smyrna, or just the females (my suspicion). but then there is this from UC Davis re: persistent and no persistent caprifigs:
Persistent Capri refers to fig that persist even when uninhabited by wasp vs. Caducous that drop when uninhabited. Persisted Caprifig is important for breeding as it segregated into persistent : Caducous in 1 : 1 proportion irrespective of fig (female parent) that is either persistent or Caducous. The Caducous caprifig produces 100% caduceus progeny irrespective the type of fig (female parent) used in crossing, which is useless.
Fig Caprifig Progeny
Caducous Caducous all caducous
Caducous Persistent 1:1 Caducous:Persistent
Persistent Caducous all caducous
Persistent Persistent 1:1 Caducous:Persistent
So, It never seems to get any easier.
I am still, also, not clear, about where San Pedro types figure in all this, where they came from and how they interact when pollinated, do the pollinated brebas produce different offspring than the pollinated main crop?
I'm getting a headache.
