“…Two S. ampelinum singleconidial isolates from Nakhon Ratchasima (Nk4-1) and Ratchaburi (Rc2-1) Provinces as described by Poolsawat et al (2009) were used for the analysis. The disease severity was estimated by lesion score (a scale of 1 to 5 based on lesion numbers per inoculated droplet: 1 = 0-6 lesions; 2 = 7-25 lesions; 3 = 26-50 lesions; 4 = 51-100 lesions; 5 = ≥100 lesions) (Poolsawat et al, 2012). Disease severity value of each hybrid was transformed using X' = (X + 1) 1/2 .…”

ABSTRACT. Downy mildew (Plasmopara viticola) and anthracnose (Sphaceloma ampelinum) are two major diseases that severely affect most grapevine (Vitis vinifera) cultivars grown commercially in Thailand. Progress of conventional breeding programs of grapevine for improved resistance to these diseases can be speeded up by selection of molecular markers associated with resistance traits. We evaluated the association between 13 resistance gene analog (RGA)-single-strand conformation polymorphism (SSCP) markers with resistance to downy mildew and anthracnose in 71 segregating progenies of seven cross combinations between susceptible cultivars and resistant lines. F 1 hybrids from each cross were assessed for resistance to downy mildew and anthracnose (isolates Nk4-1 and Rc2-1) under laboratory conditions. Association of resistance traits with RGA-SSCP markers was evaluated using simple linear regression analysis. Three RGA-SSCP markers were found to be significantly correlated with anthracnose resistance, whereas significant correlation with downy mildew resistance was observed for only one RGA-SSCP marker. These results demonstrate the usefulness of RGA-SSCP markers. Four candidate markers with significant associations to resistance to these two major diseases of grapevine were identified. However, these putative associations between markers and resistance need to be verified with larger segregating populations before they can be used for marker-assisted selection.

“…Disease assessment Disease incidence was assessed between September and March 2010/2011, 2011/2012, and 2012. Disease incidence was estimated based on the number of diseased leaves per plant on 6 vines of each of the combination of cultivar Bordô, Concord and BRS Carmem grafted in Paulsen 1103, VR 043-43 and IAC 766 rootstock were randomly selected and tagged, totaling 54 plants.…”

“…Although considered as a tropical disease (Gonçalves 1938;Brook 1973Brook , 1992Mirica 1988) it is present in several parts of the world as China, India, Canada, Brazil, Thailand (Wang et al 1998;Jindal and Bhavani 2002;Thind et al 2004;Carisse 2005;Sônego et al 2005;Poolsawat et al 2012). In Brazilian vineyards, anthracnose is the most widespread disease, damaging almost all grape cultivars, including rustic and hybrids ones (Picena 1935;Gonçalves 1938).…”

Anthracnose is a severe disease present in several grape production areas; it is considered a tropical disease. In South Brazil, high relative humidity and other conditions favor the occurrence of fungal disease in vineyards. The objective of this study was to evaluate the anthracnose incidence progress in grape leaves in three scion cultivars (Concord, Bordô and BRS Carmem) in combination with three rootstock (1103 Paulsen, VR 043-43 and IAC 766), in regional climatic conditions favorable for disease development. The experiments were carried out on ridges with semi-trellis system. The experimental design was randomized blocks, with split plots, with 4 replications and 4 plants per plot. The plots were represented by 9 different combinations. Disease incidence was assessed at two week-. At each sampling, disease was assessed 10 leaves of a same shoot of 6 plants for each cultivar/rootstock combination, for a total of 54 plants. All cultivar-rootstock combinations showed disease symptoms with highest disease incidence coinciding with the greatest amount of precipitation. Based on the relative area under the disease progress curve (AUDPC), the anthracnose incidence showed differences between seasons. Differences between rootstocks and rootstock/cultivar combinations were observed during the first and third season, but there was no consistency between the seasons, indicating that the variation in disease progress could be due to other factors, including as weather conditions, age of the vineyard and inoculum pressure.
