Tomato (Solanum lycopersicum L.) is an important economic and nutritional crop worldwide, but its production has long been heavily constrained by various diseases. This study reviews the major types of diseases affecting tomato cultivation, with a focus on the genetic basis of disease resistance in tomato. It summarizes the main strategies currently used in resistance breeding. Through case analysis of typical resistant varieties and multi-resistant hybrids, it further shows that disease resistance, yield stability, and fruit quality can be improved together. The study also highlights the key role of resistant varieties in integrated disease management systems, as well as their potential value in improving postharvest quality and extending shelf life. Finally, in response to challenges such as pathogen evolution, climate change, and emerging diseases, it is suggested that future research should strengthen the integration of multi-omics, intelligent breeding, and high-throughput phenotyping technologies, so as to promote the coordinated development of disease resistance and high-quality tomato production and achieve sustainable agricultural goals.
