The present disclosure provides tomato plants exhibiting resistance to Leveillula taurica (Lt) and lacking traits associated with linkage drag such as an undesirable orange fruit exocarp color. Such plants may comprise novel introgressed genomic regions associated with disease resistance from S. chilense. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are provided.
