Interpretive Summary:

Technical Abstract: Pepino mosaic virus (PepMV) is an emerging disease on greenhouse tomato. A major tomato germplasm core collection was evaluated for its resistance against PepMV. These accessions included 23 Solanum lycopersicum L., 8 S. pimpinellifolium L., 33 S. peruvianum L., 18 S. chilense (Dunal) Reiche, and 27 S. habrochaites Knapp & Spooner. The results showed that all plants in the accessions corresponding to S. lycopersicum and S. pimpinellifolium were susceptible to PepMV-US infection. On the other hand, two accessions of both S. peruvianum (LA107 and LA1305) and S. chilense (LA1971 and LA2748) appeared to have some levels of tolerance. However, the most promising resistance segregated in three S. habrochaites accessions (LA1731, LA2156, and LA2167). A secondary screening was carried out with progenies generated from the selected S. habrochaites plants. The segregated LA1731 plants were resistant to not only the US type but also the European type of PepMV.
