Bacterial canker of kiwifruit caused by Pseudomonas syringae pv. actinidiae (Psa) is a catastrophic disease that threatens the global kiwifruit industry. As yet, no cure has been developed. Planting resistant cultivars is considered as one of the most effective ways to control Psa. However, most existing cultivars lack Psa‐resistance genes. Wild Actinidia resources contain rich genetic diversity and may have powerful disease‐resistance genes under long‐term natural selection, but lack of knowledge about the resistance to Psa for most Actinidia species results in some excellent wild resistant genotypes being underutilized. In this study, the response to Psa of 104 wild genotypes of 30 Actinidia species (including 37 taxa) was tested with an in vitro bioassay, and a considerable number of individuals from different species with tolerance or high resistance to Psa were identified. The results showed high consistency between years. This is the first large‐scale evaluation of diverse Actinidia species with resistance to Psa through an in vitro bioassay. The resistant genotypes of A. chinensis identified could be used in future kiwifruit improvement programmes. The findings should help provide an understanding of the resistance to Psa.

野生猕猴桃种质对丁香假单胞菌 pv 抗性的评价。猕猴桃科

由丁香假单胞菌引起的奇异果细菌性溃疡病。猕猴桃（Psa）是一种威胁全球猕猴桃产业的灾难性疾病。到目前为止，还没有开发出治愈方法。种植抗病品种被认为是控制 Psa 的最有效方法之一。然而，大多数现有栽培品种缺乏 Psa 抗性基因。野生猕猴桃资源具有丰富的遗传多样性，在长期的自然选择下可能具有强大的抗病基因，但由于缺乏对大多数猕猴桃物种对 Psa 抗性的了解，导致一些优良的野生抗病基因型未被充分利用。在这项研究中，通过体外生物测定测试了 30 个猕猴桃属植物物种（包括 37 个分类群）的 104 个野生基因型对 Psa 的反应，并且鉴定了相当数量的来自不同物种的对 Psa 具有耐受性或高抗性的个体。结果表明年份之间的一致性很高。这是首次通过体外生物测定对具有抗 Psa 抗性的不同猕猴桃物种进行大规模评估。鉴定出的 A. chinensis 抗性基因型可用于未来的猕猴桃改良计划。这些发现应该有助于了解对 Psa 的抗性。
