Abstract
So far the genetics of self-incompatibility has been described in only one species of Solanum, namely, S. chacoense 1. It is an extremely variable species which occurs in north and central Argentine, Paraguay, Uruguay and south Brazil and now includes S. caldasii, S. subtilius, and S. jujuyense 2. S. chacoense has a onegene, multi-allelic, gametophytic system of self-incompatibility similar to that which has been found in three other genera of the Solanaceae, Nicotiana, Petunia, and Lycopersicon. Recently I have found that S. megistacrolobum has the same system as its sister South American species S. chacoense (in the press), whereas the two Mexican species, S. ehrenbergii, and S. pinnatisectum, have a two-gene system.
