摘要

使用包含不同菌株的病原体群体来确定特定地区葡萄品种对霜霉病病原体 Plasmopara viticola 的抗性至关重要。通过从葡萄园收集的病原体种群,采用分离叶片和叶片检测法,对 Güzülü, Özer Karası, Reçel Üzümü, Tekirdağ Çekirdeksiz, Trakya İlkeren 和 Yalova İncisi)和七个外国品种(赤霞珠、红衣主教、霞多丽、神索、伊莎贝拉、赛美蓉和佳美)进行了检测。两种检测方法的病害严重程度有明显的相关性。在两种检测方法中,Çavuş 和 Isabella 品种都没有发现孢子。在叶盘检测中,品种 Yapıncak 的病害严重程度很低(2.00%),在分离叶检测中,病原体在该品种上没有孢子。由于使用的测试方法不同,有些品种的病害严重程度也不同,因此进行了聚类分析以确定品种对病原体的抗性水平,21 个品种被分为 4 个聚类。第 I 组中的巴勒什、博兹贝、卡迪纳尔、恰武什、伊莎贝拉、赛美蓉和亚普恩查克的病害严重程度平均值最低(2.88%),而第 3 组中的赤霞珠、居兹居吕、帕帕兹-卡拉什和亚洛娃-因西斯的病害严重程度平均值最高(56.75%)。第 1 组和第 3 组中的这些品种分别被视为高抗病性和高感病品种。在这两项测定中,官方品种说明中报告的叶毛密度与病害严重程度的降低无关。这项研究首次评估了该地区葡萄品种对葡萄孢菌群的反应。鉴定出的高抗和抗病品种将为育种者提供新的材料,并有助于改善该地区的有机葡萄栽培。

Foliar Resistance to a Natural Population of Plasmopara viticola in Some Grapevine Varieties Grown in Türkiye

It is critical to use a population of the pathogen that contains different strains to determine the resistance of grapevine varieties to the downy mildew pathogen Plasmopara viticola in a specific region. This study tested six local grape varieties (Çavuş, Kalecik Karası, Müşküle, Papaz Karası, Sultana and Yapıncak), eight Turkish registered varieties (Barış, Bozbey, Güzgülü, Özer Karası, Reçel Üzümü, Tekirdağ Çekirdeksizi, Trakya İlkeren and Yalova İncisi) and seven varieties of foreign origin (Cabernet Sauvignon, Cardinal, Chardonnay, Cinsault, Isabella, Semillon and Gamay) using detached leaf and leaf disc assays with pathogen populations collected from vineyards. There was a significant correlation for disease severity between the two assay methods. No sporulation was observed on the varieties Çavuş and Isabella in both assay methods. The variety Yapıncak had very low disease severity (2.00%) in the leaf disc assay, and the pathogen did not sporulate on this variety in the detached leaf assay. Cluster analysis was performed to determine the resistance level of the varieties against the pathogen, as different disease severities were observed in some varieties depending on the test method used, and the 21 varieties were classified into four clusters. Barış, Bozbey, Cardinal, Çavuş, Isabella, Semillon and Yapıncak in Cluster I exhibited the lowest disease severity mean (2.88%), while those in Cluster 3, including Cabernet Sauvignon, Güzgülü, Papaz Karası and Yalova Incisi, had the highest disease severity mean (56.75%). These varieties in Clusters 1 and 3 were considered highly resistant and highly susceptible, respectively. Leaf hair density, as reported in official variety descriptions, did not associate with reduced disease severity in the two assays. This study assessed the response of grapevine varieties to the P. viticola population in the region for the first time. The highly resistant and resistant varieties identified will provide new material for breeders and contribute to the improvement of organic viticulture in the area.

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.
