Abstract
In tomato, Bulked Segregant Analysis was used to identify random ampli fied polymorphic DNA (RAPD) markers linked to a quantitative trait loc us (QTL) involved in the resistance to the Tomato Yellow Leaf Curl Vir us. F-4 lines were distributed into two pools, each consisting of the most resistant and of the most susceptible individuals, respectively. Both pools were screened using 600 random primers. Four RAPD markers w ere found to be linked to a QTL responsible for up to 27.7% of the res istance. These markers, localized in the same linkage group within a d istance of 17.3 cM, were mapped to chromosome 6 on the tomato RFLP map .
