Representative phenotypes of genetic populations generated from their respective parents, F1 and F2 for resistance to tomato brown rugose fruit virus. A Phenotypic expression of the resistance line (S. pimpinellifolium ‘USVL332’) and the susceptible parent (S. lycopersicum ‘Moneymaker’) and their F1 plants upon inoculation with ToBRFV US isolate (CA18-01); B Representative phenotypes of a F2 MU population generated between ‘Moneymaker’ and ‘USVL332’ with mosaic, mottling, and leaf deformation (S) and normal healthy-looking leaves (R). C Representative phenotypes of a F2 UU population generated between ‘USVL333’ and ‘USVL332’ with mosaic and mottling (S) and normal asymptomatic leaves (R)
