Analysis of wilting symptoms using F2 clones and F3 families of plants derived from a cross between the resistant tomato cultivar Hawaii7996 and the susceptible Lycopersicon pimpinellifolium line WVa7OO inoculated with a strain of bacteria (GMI8217, derived from an endemic race 1 pathogen strain) permitted the detection of six quantitative trait loci (QTL) that may be important for field resistance to Ralstonia solanacearum. Three QTL, one on chromosome 6 and two QTL on chromosome 4, confirmed results previously obtained in tests done in a culture chamber (P. Thoquet, J. Olivier, C. Sperisen, P. Rogowsky, H. Laterrot, and N. Grimsley, MPMI 9:826-836, 1996). Two putative new QTL were found on chromosomes 3 and 8. In addition, a weak putative QTL previously detected on chromosome 10 was again observed in the field. One QTL on chromosome 11 was found to be specific to F2 clones.
