Resistance to Phytophthora infestans in somatic hybrids of Solanum nigrum L. and diploid potato.

In breeding for resistance to late blight, ( Phytophthora infestans Mont. de Bary), an economically important disease affecting potatoes, the search for new sources of durable resistance includes the non-host wild Solanum species. The aim of this work was to evaluate the resistance to P.
