Identification of a QTL region for tomato brown rugose fruit virus resistance in Solanum pimpinellifolium.

ABSTRACT: Tomato (Solanum lycopersicum L.), one of the most widely grown vegetables in the world, has been seriously impacted in the past decade by the emerging tomato brown rugose fruit virus (ToBRFV). ToBRFV is a seed-borne tobamovirus, with ability to overcome the commonly used Tm-2² resistance gene in tomato. The objective of this study was to conduct quantitative trait locus (QTL) mapping and identify single-nucleotide polymorphism (SNP) markers associated with ToBRFV resistance in tomato. Two F₂ populations were used for QTL mapping: One derived from a cross between S. pimpinellifolium USVL333 (PI 390718) × USVL332 (PI 390717) and another from 'Moneymaker' × USVL332 (PI 390717), with population sizes of 195 and 79 plants, respectively. The resistance trait was derived fro
