Disease Resistance Selection
Disease resistance selection refers to breeding programs where cultivators systematically choose parent plants showing tolerance or resistance to common fungal, bacterial, or viral pathogens. These traits are often polygenic, meaning multiple genes contribute to the phenotype, making them complex to isolate and stabilize. Breeders working in this category track disease response across generations—typically selecting against powdery mildew, botrytis, and root pathogens—to reduce crop losses in varied growing environments. Selection intensity varies widely depending on climate, cultivation method, and regional disease pressure. This approach has become increasingly relevant as growers seek stable genetics requiring fewer chemical interventions.

Disease resistance traits allow breeders to develop cultivars suited to humid, challenging, or outdoor growing conditions. Stable resistance lines serve as parental stock for crossing programs aimed at maintaining vigor while reducing pathogen susceptibility.
