Abstract

provided either beneficial, neutral, or detrimental quantitative effects, depending on the loci combination and pathogen strain. In particular, the fact that defeated loci may compromise resistance highlighted important implications for the breeding of perennials. Thorough phenotypic investigations of pyramiding schemes emerge as a critical step for the effective and durable management of genetic resistances.
