I plant to cross habrochaites with domestic tomatoes.

Cool! I don't know if these were the exact papers i was reading the other day but here they are anyway.

Solanum pennellii hybridizes in both directions with L. hirsutum and unidirectionally
with L. esculentum with great ease. The high level of fertility existing between these three species
points to a close phylogenetic relationship.

For example, in our two mapping populations, the phylogenetic relationships among the three species involved are still not definitively resolved, but a consensus phylogeny based on data from AFLPs, cpDNA restriction sites, and sequences from granule-bound starch synthase and internal transcribed spacers indicates that S. habrochaites (SH) and SP share a more recent common ancestor that either species does with SL

plus S. pennellii and S. habrochaites are in the same branch next to each other on the phylogenetic tree. I think they both have small green fruits so i'm not sure exactly what if anything useful would come from such a cross, but might be interesting non-the-less. I also believe that wild plants are easier to cross as hybrids themselves than pure breds anyway, so it's possible that a pennellii x habrochaites F1 or F2 hybrid would be more genome compatible with S. lycopersicon anyway, but who knows, maybe not.
