Selection of processing tomato genotypes resistant to two spotted spider mite

Abstract: One of the major problems in cultivation of tomato is the occurrence of pests and diseases. The objective of the research was to select genotypes from the second generation of the first backcross (F2BC1) between the tomato cultivar for processing S. lycopersicum (cv. Redenção) and the wild access S. habrochaites var. hirsutum (PI-127826), with high levels of zingiberene (ZGB), resistant to the twospotted spider mite Tetranychus urticae (Acari: Tetranychidae). From the F2BC1 population. The ZGB content was quan… Show more

“…This will be a challenge and will become more difficult as the number of pests considered increases, as each plant species must be a non-host of the focal pest, but also of the other pests the mix aims to repel (introducing a plant species that repels one pest but is suitable to another risks reducing the effectiveness of the technique). For example, both marigold [31] and tomato [32] are susceptible to the two-spotted spider mite ( Tetranychus urticae Koch) and therefore as part of this mix a plant would need to be introduced to alleviate negative effects of this pest. We believe that through careful planning and constructing models of known plant-insect interactions it would be possible to create a mix of plants which mitigate arthropod pest damage to agricultural crops.…”

“…These genotypes, in some cases, showed similar degrees of resistance to the standard S. habrochaites var. hirsutum PI-127826, which was expected due to the high heritability (81.9%) of zingiberene content character in plants [22,25].…”

“…The tomato genotypes selected by Zanin et al [25] from a F 2 BC 1 population for high levels of zingiberene (RVTZ 2011-079-117, RVTZ 2011-079-185, RVTZ 2011-079-335, and RVTZ 2011-079-503) were used as parents and pollen sources for crosses with Solanum lycopersicum cv. Redenção, thus obtaining the F 1 RC 2 generation which, after self-fertilization, originated the F 2 BC 2 population.…”
