“…The colonization assay revealed the presence of significantly less pathogen than the control indicating that there may be a degree of tolerance in this accession. In the literature, LA1223 is reported to have resistance against potato Y potyvirus, the causative agent of potato Y disease (Toprak et al, 2009), tomato spotted wilt virus (Maluf et al, 1991), and heterogeneous resistance to cucumber mosaic virus (Balci, 2005). However, no information on this accession's tolerance to Cmm was found in the literature.…”

“…In the literature, LA1777 is reported to have resistance to many disease pathogens including, tomato downy mildew pathogen, Phytophthora infestans (Li et al, 2011), bacterial spot disease agent Pseudomonas syringae pv. tomato race-1 (Thapa et al, 2015), tomato yellow leaf curl begomovirus, tomato mottle mosaic disease pathogen, tomato mottle tobamovirus (Momotaz et al, 2007), and potato Y potyvirus (Toprak et al, 2009). The same accession was indicated to be effective against the insect pests tobacco whitefly (Bemisia tabaci) (Momotaz et al, 2010) and Tuta absoluta (Bitew, 2018) and was reported to have moderate tolerance to Orobanche aegyptiaca, a parasitic plant.…”

Clavibacter michiganensis subsp. michiganensis (Cmm), is a devastating bacterial disease agent causing bacterial wilt and canker in tomatoes. There is no definitive solution to prevent yield losses by Cmm in tomatoes. Moreover, there is currently no commercially successful Cmm resistant tomato cultivar on the market. Therefore, we aimed to determine the tolerance level of some tomato accessions to Cmm in the present study. For this purpose, we screened seven tomato accessions representing four species (Solanum arcanum, S. habrochaites, S. pennellii, and S. peruvianum) from Peru, Ecuador, and Mexico against the highly virulent isolates Cmm-244 and Cmm-9. A root immersion method was used to identify new sources of resistance to this important disease. Two accessions, S. habrochaites LA1777, and S. arcanum LA2157 were found to be moderate and highly tolerant, respectively, and could serve as tolerance resources for tomato breeding in Türkiye. These materials can also be investigated more extensively to determine their intrinsic Cmm tolerance mechanism.
