“…In accordance with previous results, Sauvignon Blanc and Cabernet Sauvignon showed the highest DI in the surveyed Hungarian germplasm collections, all four with their own climate and soil characteristics, while Furmint, Chardonnay and Cabernet Franc were found less GTD susceptible [12,42,43,46,55]. Blaufraenkisch (also referred to as Limberger), again confirmed by our current results, constistently one of the lowest DI [42,43,46,55], while Merlot and Pinot Noir usually were also found less susceptible to most of GTDs in general [12,42,46,55,56].…”

“…The most serious disease symptom is plant loss resulting irreversible economic damage. Previously, only foliar or chronic and dead cordon or apoplexic (partial and whole plant) individual disease expressions were differentiated amongst GTD symptoms [43,46,55]. This traditional categorization or subsequent merging different symptom manifestations and calculating disease incidence indicates only the susceptibility of a cultivar, and does not take into account the severity of the infection and the plant's responses.…”

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 mortality rate. The cultivars of monophyletic Vitis vinifera L. origin were amongst the most sensitive ones, and their sensitivity was significantly (p&lt;0.01) higher than that of the interspecific (hybrid) cultivars assessed, which are defined by the presence of Vitis species other than V. vinifera (e.g. V. labrusca L., V. rupestris Scheele, V. amurensis Rupr.) in their pedigree. We conclude that ancestral diversity of the grape confers higher degrees of resilience against GTDs.

“…The physiological and genetic background of these differences in sensitivity or resistance against GTD-causing pathogens is not understood [ 53 , 54 ]. In accordance with previous results, Sauvignon Blanc and Cabernet Sauvignon showed the highest DI in the surveyed Hungarian germplasm collections, all four with their own climate and soil characteristics, while Furmint, Chardonnay, and Cabernet Franc were found less GTD susceptible [ 12 , 42 , 43 , 46 , 55 ].

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 Vitis vinifera L. origin were amongst the most sensitive ones, and their sensitivity was significantly (p < 0.01) higher than that of the interspecific (hybrid) cultivars assessed, which are defined by the presence of Vitis species other than V. vinifera (e.g., V. labrusca L., V. rupestris Scheele, and V. amurensis Rupr.) in their pedigree. We conclude that the ancestral diversity of grapes confers a higher degree of resilience against GTDs.

“…Among the different pests and diseases that compromise the viability and economic profitability of grapevine culture worldwide, grapevine trunk diseases (GTDs) cause great damage to plantations, decreasing productivity and reducing the useful life of the plant (Serra et al 2021), with associated annual replanting costs estimated at over $1500 M (Hofstetter et al 2012). GTDs caused by certain species of pathogenic fungi have in common that these taxa produce an internal alteration of the wood that they parasitize, producing phenomena of vascular necrosis, delayed growth, foliar symptoms, or root rot, leading to the death of the plant in an indeterminate period (from 1 to 30 years), but normally long (Luque i Font 2014).…”

“…Concerning Botryosphaeria dieback, up to date some varieties and rootstocks more tolerant to Botryosphaeriaceae have been identified (Ramsing et al 2021;Travadon et al 2013;Billones-Baaijens et al 2014;Chacon-Vozmediano et al 2021;Chacon et al 2020;Sosnowski et al 2022;Serra et al 2021;Ramirez et al 2018;Guan et al 2016). For instance, 'Bobal', 'Monastrell', 'Macabeo', 'Moscatel serrano', 'Caíño Longo', 'Caíño Tinto', 'Torrontés', 'Treixadura', and 'Dona Branca' cultivars have been reported to be more resistant to N. parvum than other varieties (Gramaje et al 2020;Chacon et al 2020).…”

Screening of Vitis vinifera cultivars from the Grapevine Germplasm Bank of Aragon for susceptibility to Botryosphaeria dieback fungi

Grapevine trunk diseases (GTDs) are taking the forefront of winegrowers’ concerns, as they cause considerable damage in vineyards not only quantitatively but also qualitatively. Furthermore, in the last three decades, an increasing incidence of the socioeconomic impact of these fungal pathologies has been observed. To date, no effective control strategies or curative treatments are available for these diseases that can replace the effectiveness offered by a series of chemical synthesis fungicides currently prohibited by European legislation. In this scenario, screening for less sensitive cultivars is regarded as a sustainable approach for GTDs management. In the study presented herein, the tolerance/susceptibility of 25 cultivars from the Grapevine Germplasm Bank of Aragon (Movera, Zaragoza, Spain) including commercial, local, or minority germplasm, was tested against two pathogens associated with Botryosphaeria dieback (viz. Neofusicoccum parvum and Diplodia seriata), which were inoculated in a detached cutting assay under open-air conditions. Based on lesion length development after eight months, significant differences were detected among the cultivars in the length of internal (vascular) necroses. In general terms, all cultivars were susceptible to fungal infection, but ‘Macabeo’ and one of the ‘Garnacha Tinta’ ecotypes under study (from Villanueva de Huerva, Zaragoza) would be the least susceptible white and red cultivars, respectively. On the other hand, ‘Monegrina’, ‘Grumel’, and ‘Torcijón’ would be among the least tolerant cultivars to fungal infection.
