ABSTRACT This study demonstrates resistance in Actinidia chinensis var. deliciosa germplasm to the armoured scale insect Hemiberlesia lataniae, an important pest of kiwifruit in New Zealand. A bioassay was used to test the resistance of 120 vines from a germplasm collection in New Zealand. Fourteen of the vines were classified as resistant and five as moderately resistant. Eight crosses (two Susceptible (S) × Resistant (R); 1 R×S; 4 R×R; 1 S×S) were made from the original vines, and the resulting families examined for resistance. There were large differences in insect survival and size between the families. Three families from R×R parents and one from R×S parents had vines showing a hypersensitive-type response (plant cell death) to H. lataniae. There were large differences in the range of susceptibility to H. lataniae within families, suggesting that the trait is polygenic or that more than one resistance mechanism is present in the germplasm.

测试猕猴桃（Actinida chinensis var. deliciosa）种质对 Hemiberlesia lataniae 的敏感性

摘要 本研究证明了猕猴桃变种的抗性。deliciosa 种质是装甲介壳虫 Hemiberlesia lataniae，新西兰奇异果的一种重要害虫。使用生物测定法测试了来自新西兰种质资源的 120 株葡萄藤的抗性。14 株葡萄藤被归类为具有抗性，5 株被归类为中等抗性。从原始葡萄藤中进行了八个杂交（两个易感 (S) × 抗性 (R)；1 个 R×S；4 个 R×R；1 个 S×S），并对由此产生的家族进行抗性检查。各科之间昆虫的存活率和大小存在很大差异。来自 R×R 亲本的三个家庭和来自 R×S 亲本的一个家庭的葡萄藤对 H. lataniae 表现出超敏反应（植物细胞死亡）。家庭内对H. lataniae的易感性范围存在很大差异，
