Mini tomato genotypes resistant to the silverleaf whitefly and to two-spotted spider mites.
Acyl sugars and whitefly (Bemisia tabaci) resistance in segregating populations of tomato genotypes
The wild tomato, Solanum pennellii, is an important source of resistance genes against tomato pests. This resistance is due to the presence of acyl sugars (AS), which are allelochemicals that have negative effects on arthropod pests. There are no commercially available tomato cultivars that exhibit significant levels of resistance to arthropod pests.
Differential responses of one hundred tomato genotypes grown under cadmium stress
Due to increased global concern over the deleterious effects of toxic heavy metals in the environment, it has become necessary to develop plant genotypes that limit the uptake of heavy metals to aerial edible parts. To address this concern, we performed a glasshouse experiment to assess variations within tomato germplasm for cadmium (Cd) tolerance under control conditions and under simulated stress conditions. Significant differences (P < 0.01) were observed among all genotypes at both Cd levels (3 ppm and 6 ppm).
Indirect selection of industrial tomato genotypes rich in zingiberene and resistant to Tuta absoluta Meyrick
Obtaining tomato cultivars resistant to pests through interspecific crosses between commercial cultivars and wild accessions is an important tool in integrated pest management. The aim of this study was to select tomato genotypes with high zingiberene (ZGB) levels that are resistant to the South American tomato moth (Tuta absoluta Meyrick) and to estimate genetic parameters of ZGB inheritance from the interspecific cross Solanum lycopersicum cultivar ‘Redenção’ x Solanum habrochaites var. hirsutum (PI-127826 accession).
