Abstract Bulked segregant analysis and high-resolution mapping were used to pinpoint the position of the Lv gene for resistance to Leveillula taurica in tomato. Mapping in an F2, corresponding to more than 3800 gametes, indicates that Lv is positioned within the 0.84-cM interval defined by the RFLP markers CT121 and CT129, with the closest marker, CT121, being only 0.16 cM from the gene. The tight linkage of these markers demonstrates their usefulness in marker-assisted breeding for Lv, and the high-resolution map provides a starting a starting point for positional cloning of this resistance gene.
