Common figs ripen in absence of the wasp, and do so Parthenocarpically. The seeds will not be viable if not pollinated in this instance. Only caprifigs produce pollen.
There's some pretty large collections in California, especially in the local area. Several members of the CRFG have sizeable collections of sought after varieties and bring their scions to the January exchange.
For optimization, there are two challenges that can be somewhat alleviated with different rootstocks/hybridization.
For rootstocks, a drought tolerant-vigorous-nematode proof rootstock is desired. There are two such options (that I'm aware of, FloridaFruitGeek may know of more), F.sycamorus, and F.palmata. I haven't been able to find much on the drought tolerance of F.Palmata, and F.Sycamorus seems to NEED air layering, as I've not been able to root it no matter how determined. I just lost another air layer of it this week, so even that isn't the easiest.
I've been searching for a male F.Palmata, as I have read that if it is the pollen parent, the offspring are immune to FMV, and the roots are less susceptible to nematodes, a big problem in light, sandy soils, as the trees only seem to thrive for one year, and then are stunted. A few varieties seem to have some resistance such as Excel. It appears that Excel is not hindered by the RKN at all.
Fig breeding is much easier with the wasp, as you can take a caprifig of the desired male and bag it with the fig you are trying to pollinate.
There's really good info
here.
