The document summarizes tomato genetics and breeding research at Penn State University. The goals are to identify genetic sources of desirable traits like disease resistance and fruit quality, understand the genetic basis of traits, develop genetic maps and markers, identify genes and QTLs for traits, and develop tomato breeding lines and cultivars using traditional and marker-assisted breeding. Traits of interest include disease resistance to early blight and late blight, lycopene content, abiotic stress tolerance, and adaptation to Northeast growing conditions. Various genetic resources have been screened, genetics experiments conducted, genetic maps developed, QTLs identified, and breeding lines with traits like disease resistance and high lycopene content have been developed for different tomato types
