Abstract The tomato-potato psyllid (TPP), Bactericera cockerelli, is a vector for the phloem-limited bacterium Candidatus Liberibacter solanacearum (Lso), the causative agent of economically important diseases including tomato vein-greening and potato zebra chip. Here, we screened 11 wild tomato relatives for TPP resistance as potential resources for tomato (Solanum lycopersicum) cultivar development. Six accessions with strong TPP resistance (survival <10%) were identified within S. habrochaites, S. pennelli, S. huaylasense, S. chmielewskii, S. corneliomulleri, and S. galapagense. Two S. pennelli and S. corneliomulleri accessions also showed resistance to Lso. We evaluated recombinant inbred lines (RILs) carrying resistance from S. habrochaites accession LA1777 in the S. lycopersicum background and identified major quantitative trait loci (QTLs) responsible for adult TPP mortality and fecundity in several RILs carrying insertions in different chromosomes, indicating the polygenic nature of these traits. Analysis of a major resistance QTL in RIL LA3952 on chromosome 8 revealed that the presence of Lso is required to increase adult TPP mortality. By contrast, the reduced TPP oviposition trait in LA3952 is independent of Lso. Therefore, resistance traits are available in wild-tomato species, although their complex inheritance and modes of action require further characterisation to optimise their utilisation for tomato improvement.

Fusarium wilt caused by different Fusarium species is a devastating disease causes heavy loss to tomato plantation worldwide. In this study 13 tomato varieties were screened against F. equiseti to explore the resistance potential of the varieties against the disease. Out of 13 varieties only 2 varieties Roma and Hybrid showed resistance to the disease, while the other 69% were highly susceptible. Based on cluster analysis for genetic diversity it was reported that susceptible varieties are only 8% genetically different and share same genetic pool. We reported that the wild species of tomato Solanum pimpinellifolium (Sp- 2093) showed complete immunity and were remain unaffected having 25% genetic difference with other varieties tested. Thus wild tomato species may provide the source of resistance required to develop resistant variety against the emerging wilt pathogen F. equiseti. The data regarding virluence structure and resisatnt variety that is presented in this study will suport more focused efforts in the management of tomato wilt caused by Fusarium species and that resistant features of wild tomato variety Sp-2093, could be accumulated with other desirable characteristics of different germplasm in one cultivar, which will reduce the chances for new virulent species to evolve.
