The diploid cultivated and wild species, which represent 70 percent of all tuber-bearing species of Solanum, are the supply of germplasm and a source of genetic diversity and genes of resistance and starch, protein and dry matter content. They are crossed very easily with dihaploid forms of Solanum tuberosum. Both are used in potato research and breeding programmes. Dihaploid clones and diploid species of our collection aare planted in the field in the form of 15, 10 qnd 5 tubers according to virus resistance, tuber characteristics, fertility and unreduced gametes production. The best clones are maintained in vitro. About 600 clones are maintained in field collections, 80 clones in vitro, and Solanum phureja, S. maglia, S. brevidens, S. bulbocastanum, S. vernei, S. chacoense, S. gourtei and S. berthaultii
