I checked, and the only ones that do cross fairly easily are annuum and chinense. Probably chinense and frutescens. There are a few such crosses around. The problem is that many seeds from such crosses have problems. Check pimenta da Neyde
Some others are possible, but I think on the anecdotic side.

Yep, have Chinense, baccaum and annuum! Tabogo Seasoning, Aji Amerillo...and just about everything else is an annuum including the Aleppo's!
That took some time to check every last pepper.

All will cross, but the resulting hybrids have varying degrees of sterility. Annuum x chinense will still be mostly fertile, but annuum x baccatum and chinense x baccatum will both have poor fertility. Here's the results of the pollen study:  |

As far as I know, rocoto (C. pubescens) won't cross with pretty much anything else easily except for that little bitty one whose species name begins with "U" (I want to say ulucuo, but I think that is something else) |

The diagram from the page I posted earlier (https://www.flickr.com/photos/darrenabbey/8302757528) suggests that C. pubescens can cross with C. frutescens, C. eximem, and C. cardenasii with varying difficulty.

Thanks Dar. That pretty much says all my potential crosses would germinate normally, so I'll have to isolate as much as possible. Most likely I'll end up using gelatin capsules to isolate blooms until after pollination, as someone suggested earlier. Do you have a similar chart on tomatoes? I just traded for my first Solanum pimpinellifolium...

Including Solanum lycopersicum, there are currently 13 species recognized in Solanum section Lycopersicon. Three of these species—S. Cheesmaniae, S. Galapagense, and S. Pimpinellifolium—are fully cross compatible with domestic tomato. Four more species—S. chmielewskii, S. habrochaites, S. neorickii, and S. pennelli—can be readily crossed with domestic tomato, with some limitations (can only be crossed in one direction, usually S. Lycopersicum as female parent). Five species—S. arcanum, S. chilense, S. corneliomulleri, S. huaylasense, and S. peruvianum—can be crossed with domestic tomato with difficulty and usually require embryo rescue to produce viable plants. The Lycopersicon section has not been fully sampled within wild species in the South American range, so new species may be added in the future.
Solanum section Lycopersicoides and section Juglandifolium are represented by two species each that are considered bridge species genetically intermediate between tomato and non-tuber bearing potato species. S. Lycopersicoides can be crossed with domestic tomato and introgression lines [70] have been developed. This species was significant in moving the domestic tomato from separate genus status into the Solanum group because it directly links the tomato into the potato family.
S. Pimpinellifolium will readily cross with domestic tomato in both directions. This is a handy species given that disease and pest tolerance genes are available and can be readily bridged over into domestic tomato via breeding. I am growing F2 plants from a cross of Piennolo del Vesuvio X S. Pimpinellifolium LA0417. The wild species plant LA0417 was exceptionally disease tolerant in my garden in 2013. I'm hoping to recover the desirable genes in a more nearly domesticated plant this year.

Interesting, but wrong thread? |

It is the right thread abbey. Read above.

Sorry. The thread was focussed on crossability of pepper (Capsicum) species, and I forgot it had extended to similar information relating to tomatoes.
