Grape production worldwide is increasingly threatened by grapevine trunk diseases (GTDs). No grapevine cultivar is known to be entirely resistant to GTDs, but susceptibility varies greatly. To quantify these differences, four Hungarian grape germplasm collections containing 305 different cultivars were surveyed to determine the ratios of GTDs based on symptom expression and the proportion of plant loss within all GTD symptoms. The cultivars of monophyletic L. origin were amongst the most sensitive ones, and their sensitivity was significantly ( < 0.01) higher than that of the interspecific (hybrid) cultivars assessed, which are defined by the presence of species other than (e.g., L., Scheele, and Rupr.) in their pedigree. We conclude that the ancestral diversity of grapes confers a higher degree of resilience against GTDs.

全球葡萄生产日益受到葡萄藤主干病害（GTDs）的威胁。目前已知没有葡萄品种对GTDs具有完全抗性，但易感性差异很大。为了量化这些差异，对四个包含305个不同品种的匈牙利葡萄种质资源库进行了调查，以根据症状表现确定GTDs的比例以及所有GTD症状中植株损失的比例。单系起源于欧洲葡萄的品种是最敏感的品种之一，其敏感性显著（<0.01）高于所评估的种间（杂交）品种，种间（杂交）品种在其谱系中除了欧洲葡萄（例如欧亚种葡萄、沙地葡萄和河岸葡萄）外还存在其他物种。我们得出结论，葡萄的祖先多样性赋予了对GTDs更高的恢复力。
