Four Solanum polyadenium crossed with Solanum berthaultii, Solanum chacoense and Solanum phureja were evaluated for resistance to Premnotrypes vorax. From the set of 397 hybrids evaluated, six (1.52%) were selected for resistance. For other agronomical and biochemical characteristics the most promising hybrids were the 12th, the 14th and the 15th from the second family (498096.1- S. polyadenium X S. phureja).
