S. peruvianum is from Peru and Ecuador and In their native habitat, plants of S. peruvianum. grow in very arid areas, in some places receiving moisture only from the heavy winter fogs in the "lorna" belt. They grow as long-lived perennials, sending up new vigorous shoots during the moist period and dying back to the crown shortly there after. It seems possible that, as the soil dries out after the short wet season, the plants might pass through successive stages of normal incompatibility, pseudo-fertile fruit-set (which might serve as a device to assure seed setting in the absence of vectors or of nearby compatible plants), and then complete unfruitfulness as the previously set fruits are matured.
S. peruvianum is self-incompatible and needs other peruvianums nearby for pollination and to set fruit.*(See video below f0r an exception)
Wild tomatoes such as S. peruvianum have primarily been used by breeders to provide the disease and pest resistance to domesticated tomatoes that was lost during the domestication process. Because of that, the potential of S. peruvianum has yet to be exploited, especially so when it's estimated pervianum has more genetic diversity then all the other species combined.
L. peruvianum Is the Origin of RKN Resistance in Tomato In the early 1940s screening of large numbers of tomato lines for resistance to RKN revealed that the cultivated tomato is fully susceptible. In the same survey some wild tomato relatives from the genus Lycopersicon were included and certain strains of the remote species L. peruvianum showed a high level of resistance. Romshe suggested the use of L. peruvianum as a parent for the development of nematode resistant varieties. With the help of an embryo culture, a hybrid between L.esculentum cv.Michigan State Forcing and L. peruvianum accession P.I. 128657 was raised by Smith. Backcrossing programs of the single hybrid plant were run simultaneously by two groups, one in Davis, California and the other in Hawaii, and resulted in two L. esculentum lines, respectively VFN8 and Anahu, homozygous for resistance to M. incognita. The symbol Mi was assigned for the resistance in these lines after the first letters of Meloidogyne incognita.
