Abstract

Phytophthora capsici can induce severe economic losses in the tomato (Solanum lycopersicum) crop. However, broad-spectrum and phenotypically stable sources of resistance to this highly variable pathogen are not yet identified in Solanum (section Lycopersion) germplasm. We evaluated, in three bioassays, the reaction of Solanum (Lycopersicon) accessions against seven P. capsici isolates. All isolates across all bioassays induced severe symptoms in the susceptible control Capsicum annuum ‘Tico’. The Ralstonia solanacearum-resistant tomato ‘Hawaii-7996’ displayed superior levels of resistance to four isolates, whereas S. habrochaites ‘WIR-7924’ displayed resistance to five isolates. The resistant/susceptible reactions of the accessions were not coincident, indicating the presence of isolate-specific resistance factors as well as potential pathogen pathotypes. Large-spectrum genetic resistance to P. capsici isolates is essential for sustainable management of this pathogen. Hence, combining resistance factors from ‘Hawaii-7996’ and S. habrochaites ‘WIR-7924’ into a single cultivar would be a promising breeding strategy aiming to develop tomatoes with resistance to a wide array of P. capsici isolates.

茄属植物和茄科植物对新热带疫霉属种的广谱和表型稳定抗性

疫霉菌（Phytophthora capsici）会给番茄（Solanum lycopersicum）作物造成严重的经济损失。然而，在茄科植物种质中尚未发现对这种高度多变的病原体具有广谱且表型稳定的抗性来源。我们在三项生物测定中评估了茄科植物对七种荚膜梭菌分离物的反应。在所有生物测定中，所有分离物都会诱发易感对照品 Capsicum annuum 'Tico' 出现严重症状。对 Ralstonia solanacearum 有抗性的番茄'Hawaii-7996'对四种分离物表现出了超强的抗性，而 S. habrochaites 'WIR-7924' 则对五种分离物表现出了抗性。这些品种的抗性/易感性反应并不一致，这表明存在分离物特异性抗性因子以及潜在的病原体病型。对 P. capsici 分离物的大范围遗传抗性对于该病原体的可持续管理至关重要。因此，将'Hawaii-7996'和 S. habrochaites 'WIR-7924'的抗性因子结合到一个单一的栽培品种中，将是一种很有前景的育种策略，其目的是培育出对多种蘑菇伞菌分离物具有抗性的番茄。

期刊介绍： Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays. Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes. Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
