A novel non-trichome based whitefly resistance QTL in Solanum galapagense

Abstract The greenhouse whitefly Trialeurodes vaporariorum is a major threat in tomato cultivation. In grown tomatoes non-trichome based resistance may be better suited than glandular trichome as trichomes interfere with biocontrol, which widely used. Analysis of collection recombinant inbred lines derived from cross between Solanum lycopersicum and galapagense showed to the T. on plants without type IV. affected adult survival (AS), but not oviposition rate. This indicates that S. , addition resistance, also carries components. effectiveness appeared depend season were grown. had small significant effect Bemisia tabaci thrips Frankliniella occidentalis . A segregating F 2 population was created map resistance. Two Quantitative trait loci (QTLs) for reduced AS mapped chromosomes 12 7 (explaining 13.9% 6.0% variance respectively). QTL chromosome validated F3 lines.
