  Apple replants disease (ARD), incited by a soil borne pathogen complex, is a major obstacle to establishing an economically viable apple orchard at replant sites. The predominant control method is pre-plant chemical fumigation of orchard soil, which is expensive and comes with environmental and regulatory concerns. To maximize the exploitation of host resistance for ARD management, high quality resistance phenotypes in apple roots to ARD pathogen infection are required for elucidating the underlying resistance mechanisms. In this study, root resistance responses to Pythium ultimum infection were systematically evaluated among the ‘Ottawa 3’ × ‘Robusta 5’ (O3R5) F1 progeny. Tissue culture-based micro propagation was employed to generate genetically-defined and age-equivalent apple plants for repeated infection assays. A wide range of plant survival rates w.. View More»
