Development of BC3F2 Tomato Genotypes with Arthropod Resistance Introgressed from Solanum habrochaites var. hirsutum (PI127826)

Arthropod pests are among the biggest problems faced in tomato production worldwide. To overcome losses caused by these pests, one of most sustainable and economical strategies is use resistance introgressed from wild species. We aimed to develop BC3F2 genotypes with high levels zingiberene (ZGB) whitefly (Bemisia tabaci biotype B), South American pinworm (Tuta absoluta), two-spotted spider mite (Tatranychus urticae), accession Solanum habrochaites var. hirsutum (accession PI127826). The quantification ZGB 520 parentals yielded selection five content three low content, which were then infested B. tabaci, T. absolute, urticae. In eight parents, types amounts trichomes on leaves determined. Additionally, molecular markers used identify a higher recurrent genome recovery. results confirmed transfer S. showed that this seems be directly related concentrations presence type IV trichomes.
