Resistance to many arthropods, including Liriomyza species, is known to be
present in accessions of Lycopersicon hirsutum (f. typicum or f. glabratum)
. From the cross L. esculentum cv. Moneymaker and L. hirsutum f. glabratum
G1561 100 F-2 plants were screened in a no-choice test for resistance to Li
riomyza trifolii. The Bulked Segregant Analysis approach was used to find R
andom Amplified Polymorphic DNA markers linked to resistance. Two markers w
ere located on chromosome 2. Restriction Fragment Length Polymorphisms cons
tructed a more detailed genetic linkage map for part of chromosome 2. Krusk
al-Wallis analysis showed that this chromosome harbored a Quantitative Trai
t Locus (QTL) for number of pupae, number of mines and damage. At least one
major QTL is essential for resistance and this QTL is located on chromosom
e 2 nearby the location of the tomato probe TG451.
