Currently, resistant cultivars of tomato are not available as a management tactic because breeding programmes lack sources of resistance. Therefore, the objective of this study was to identify sources of resistance in tomato to \u003cjats:italic\u003eCLsoB\u003c/jats:italic\u003e. Forty‐six landraces of tomato were collected from several states in Mexico and were inoculated with \u003cjats:italic\u003eCLsoB\u003c/jats:italic\u003e using 20 infested adults of \u003cjats:italic\u003eBactericera cockerelli\u003c/jats:italic\u003e per plant. Two assays were done over two years under greenhouse conditions. In the first trial, landraces FC22 and FC44 showed a significantly higher proportion of resistant plants, less symptom severity and longer incubation time compared with the other forty‐four landraces and two susceptible cultivars. In the second assay, resistance to \u003cjats:italic\u003eCLsoB\u003c/jats:italic\u003e of the landraces FC22 and FC44 was confirmed because they had again significantly greater numbers of resistant plants, less symptom severity, relative lower \u003cjats:italic\u003eCLsoB\u003c/jats:italic\u003e titers and longer incubation time relative to the other genotypes. All plants considered resistant from both assays had DNA of \u003cjats:italic\u003eCLsoB\u003c/jats:italic\u003e. Results indicate that all resistant plants from these landraces are promising sources for the development of tomato cultivars with resistance to \u003cjats:italic\u003eCLsoB\u003c/jats:italic\u003e.\u003c/jats:p\u003e","long_citation_html":"Garzón‐Tiznado et al.
