Basic and applied research programs can both benefit by approaching concerns regarding resistance to herbivores from a perspective centering on natural selection and genetic architecture of resistance. In natural systems, quantification of selection, determination of genetic correlations with other traits, and evaluation of genetic architecture can enhance our ability to predict the evolution of plant resistance. This chapter explores the selective agents that influence plant resistance to insect herbivores, the strength of selection, and the genetic architecture of resistance traits. It also discusses the relationship between plant hybrid resistance and the resistance of parental populations or species, which have implications for hybrid zone dynamics and for introgression of resistance traits between populations or species. Moreover, the chapter looks at the trade-offs between resistance and tolerance, allocation costs to resistance, ecological costs to resistance, potential impacts of hybridization, and the architecture of resistance in willows Salix eriocephala and Salix sericea.

Keywords:   Salix eriocephala, Salix sericea, willows, natural selection, resistance, tolerance, herbivores, genetic architecture, introgression, hybridization
