Abstract

A gene-for-gene model is postulated to explain the observed interactions between cultivars of strawberry and races of Phytophthora fragariae. Five interacting resistance (R1 · R5) and avirulence (Avr1 Avr5) factors explain all the available data involving 15 host genotypes, including the USA and Canadian differential series, and 12 pathogen isolates from North America. Interactions between pathogen isolates and UK and German differentials are also explained by the proposed model. The model makes it possible to develop a universally applicable differential series, to present a systematic, unequivocal nomenclature of races, and to increase the efficiency of breeding programs.
