“…Ten genotypes showed high to moderate resistance level to Bt-MED in both experiments at 28 d post infestation (Table 2), also suggesting presence of an antibiosis mechanism in these genotypes because they significantly reduced the different biological stages (eggs, nymphs, and new adults) of this insect compared to the commercial cultivar Bonny Best (Table 2). Toscano et al (2002) and Neiva et al (2018) have reported similar results regarding moderate and high levels of resistance to whiteflies in wild genotypes of tomato. Therefore, these genotypes are promising sources of resistance that may be used for the development of tomato cultivars with different resistance levels to BtMED.…”

“…These species are among the most important globally because they remain in quarantine status in several countries (De Barro & Ahmed 2011). Different whitefly control methods are used currently, among them chemical and applied biological control (Neiva et al 2018). Other control tactics like genetic resistance may be used to complement the integrated management of this insect.…”

“…Studies with other tomato lines have also shown a positive correlation between zingiberene content and resistance to these pest arthropods [7,52,53]. Genotypes with a high zingiberene content (ZGB-703 and ZGB-704) had a lower oviposition and a lower number of nymphs of whitefly when compared with genotypes with a low acyl-sugar (AS) and zingibrene content (Santa Clara, TOM-695, TOM-556, and TOM-584) [54].…”

Tomato Breeding for Sustainable Crop Systems: High Levels of Zingiberene Providing Resistance to Multiple Arthropods

et al. 2020

In sustainable cropping systems, the management of herbivorous arthropods is a challenge for the high performance of the tomato crop. One way to reduce the damage caused by these pests is the use of resistant cultivars within a sustainable integrated management system. The host selection of Tetranychus urticae, Bemisia tabaci, and Tuta absoluta was evaluated, characterizing their preference among the tomato genotypes RVTZ2011-79-503-143, RVTZ2011-79-335-164, RVTZ2011-79-185-250 (high zingiberene content—HZC), and RVTZ2011-79-117-273 (low zingiberene content—LZC). Such genotypes were selected in the F2BC2 generation (the F2 generation of the 2th backcross towards Solanum lycopersicum after the inicial interspecific cross S. lycopersicum × S. habrochaites var. hirsutum), resulting from crossing Solanum habrochaites var. hirsutum PI-127826 (HZC and resistant to mites) and the commercial cv. Redenção (S. lycopersicum) (LZC and susceptible to mites). In choice and no-choice bioassays by T. urticae, and in choice bioassays by B. tabaci and T. absoluta, arthropods preferred to stay and oviposit in an LZC genotype. In contrast, genotypes with HZC showed repellency to pests and induced a non-preference for oviposition. The F2BC2 genotypes selected for HZC are considered sources of resistance genes to these pests for tomato breeding programs, and therefore have excellent potential for sustainable cropping systems. These results represent an advance in obtaining tomato genetic materials which can be used in sustainable production systems with less loss from pests.

“…Pada Solanum pimpinellifolium (currant tomato-tomat kismis) dengan trikoma daun tipe IV yang memproduksi acylsugars menunjukkan tahan terhadap serangan B. tabaci (Rodriguez-Lopez et al 2011;Firdaus et al 2012). Tanaman tomat dengan acylsugars tinggi menyebabkan oviposisi kutukebul yang lebih rendah dan jumlah nimfa yang lebih sedikit dibandingkan dengan genotipe dengan kandungan acylsugars yang rendah (Neiva et al 2018). Tomat yang tahan B. tabaci, memproduksi acylsugars secara efektif mampu mengendalikan penyebaran ToCV dibandingkan dengan galur yang hampir isogenik tanpa trikoma tipe IV dan sekresi acylsugars (Fortes et al 2020).…”

Tomato chlorosis crinivirus (ToCV) diketahui berasosiasi dengan penyakit kuning pada tanaman tomat. Infeksi Crinivirus menunjukkan peningkatan di beberapa daerah di Jawa Barat saat ini. Tersedianya varietas tomat tahan akan menjadi cara efektif dalam pengelolaan penyakit virus, namun perlu upaya mencari sumber ketahanan tanaman terhadap infeksi virus. Penelitian bertujuan menentukan tingkat ketahanan 12 galur tomat terhadap infeksi ToCV. Tomat uji berumur 14 hari setelah pindah tanam diinokulasi dengan ToCV menggunakan 10 ekor kutukebul (Trialeurodes vaporariorum) viruliferus per tanaman. Pengamatan dilakukan terhadap peubah penyakit (periode inkubasi, insidensi dan keparahan penyakit, titer virus) dan peubah agronomi (tinggi tanaman, jumlah daun, jumlah dan bobot buah). Rata-rata periode inkubasi berkisar 9.4–13.5 hari, dan insidensi penyakit berkisar 90.9–100%. Gejala visual bervariasi dari klorosis ringan sampai sedang dan daun menggulung ke atas dengan skor keparahan penyakit berkisar 1.0–3.0. Titer virus diukur berdasarkan nilai absorbansi ELISA, yaitu berkisar 0.358–1.122. Secara umum, infeksi ToCV menghambat pertumbuhan tanaman dan menurunkan jumlah daun, menghambat bobot dan jumlah buah berturut-turut sebesar 6.0–37.8%, 8.6–39.5%, 2.7–33.7% dan 7.0–25.5%. Berdasarkan peubah penyakit, respons galur tomat dapat dikategorikan rentan (BISILB#1029A, BISILB#22, dan BISILB#724B), moderat tahan (BISILB#825B, BISILB#60D, BISIKC#402, BISIKC#96D, dan BISILB#40I), dan tahan (BISILB#1372ORA, BISILB#703A, BISILB#703B, dan BISILB#724A). Namun, sifat ketahanan galur tomat tersebut tidak berkorelasi dengan kemampuan produksi tanaman. Oleh karena itu, perlu dilakukan perbaikan sifat ketahanan pada empat galur tersebut agar lebih adaptif terhadap faktor lingkungan budi daya sehingga dapat dimanfaatkan sebagai tetua varietas tomat unggul tahan ToCV.
