Figure 7

F1 hybrids between a PSTVd-sensitive wild tomato and PSTVd-tolerant wild relatives were tolerant to PSTVd. At 2 weeks post-inoculation (wpi), S. l. cerasiforme LA1286 showed severe leaf curling, whereas S. l. cerasiforme LA1286 × S. pimpinellifolium LA0373 F1 or S. l. cerasiforme LA1286 × S. chmielewskii LA1028 F1 showed very mild leaf curling or was asymptomatic. At 3 wpi, S. l. cerasiforme LA1286 exhibited stunting and vein necrosis, whereas S. l. cerasiforme LA1286 × S. pimpinellifolium LA0373 F1 recovered from mild symptoms and both F1 hybrids were asymptomatic even after lethal PSTVd-AS1 infection.
