Plant resistance is a result of interaction between host, pathogen, environment and temporal factors. Major or “R” gene resistance may break down following the emergence of virulent isolates of a pathogen. Limited durability of R genes has opened the door for the utilization of slow disease resistance in crop breeding. Plant pathogens with high reproduction ability exhibit greater genetic diversity leading to loss of major gene-based resistance. Consequently, minor genes-based resistance can be effectively employed against all the available virulent isolates within a pathogen population, including non-elicitor producing pathogens. Several researchers have identified valuable genetic sources by screening germplasm collections and characterizing genes conferring slow disease development. The identification and possible cloning or tagging of such genes obtained from crop wild relatives will create better opportunities for their use in crop improvement. Nevertheless, very little information is available about the nature of individual genes responsible for slow disease development. A thorough understanding of the nature of inheritance of slow disease resistance, interactions, and the possible breeding strategies to enhance resistance governed by slow disease components will help in breeding or developing resistant cultivars with enhanced yield. This review discusses the components of SDD in terms of identification, characterization, factors influencing it, and breeding strategies to enhance resistance governed by SDD components. Furthermore it emphasizes the importance of targeted breeding strategies to exploit the potential of SSD in developing cultivars with enhanced resistance and maintaining a good yield.
