Selection of F 2 BC 1 tomato genotypes for processing containing high levels of zingiberene and resistant to tomato pinworms Daniel Suek Zanin & Juliano Tadeu Vilela de Resende & André Ricardo Zeist & Renato Barros de Lima Filho & André Gabriel & Flávia Cristina Panizzon Diniz & Amanda Carvalho Perrud & Rafael Gustavo Ferreira Morales Received: 4 December 2019 /Accepted: 17 September 2020 # Springer Nature B.V. 2020 Abstract An alternative for the management of the tomato moth is genetic resistance obtained through in- terspecific crosses. The aim of this study was to select genotypes from the second generation of the first backcrossing (F 2 BC 1 ) between the cultivar Redenção, which presents processing characteristics, and the wild access Solanum habrochaites var. hirsutum ‘ PI- 127826’, containing high levels of zingiberene and re- sistant to tomato moths, using different damage evalua- tion methodologies. For this purpose, F 2 BC 1 genotypes with different zingiberene levels were submitted to a pest resistance test comprising ten treatments. The treat- ments consisted of five F 2 BC 1 genotypes with high zingiberene content, three with low content, and the parental plants. The damage caused by the caterpillars were evaluated using two methodologies, a graded vi- sual evaluation and estimates of the percentage of dam- aged leaf areas. Additionally, population growth was evaluated based on the count of the number of caterpil- lars present on leaflets. Zingiberene-rich F 2 BC 1 geno- types were less damaged compared to those containing low levels of this substance and the recurrent parent. The two methodologies for assessing damages were demonstrated as feasible. The RVTZ 2011–079-117 and RVTZ 2011–079-335 genotypes presented poten- tial as resistant tomato moth sources.
