Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith
Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith
MSU Graduate Theses
Grapevine vein clearing virus (GVCV) is a recently discovered virus belonging to the Badnavirus genus. Characteristic to its name, the virus is associated with a disease where symptoms manifest as pronounced vein-clearing, resulting in severe berry deformation and vine decline in susceptible grape varieties. Sustainable production of wine is dependent on healthy plants. The associated disease is mainly found in Midwest vineyards. Attempts were made in this thesis to provide evidence of causality of the virus to the associated disease and to infer the historical path and migration pattern of GVCV. Conclusions and discussions will provide grape producers with the …

An Assessment Of Seven New Grape Varieties And A Study Of Grapevine Vein Clearing Virus In Native Vitaceae Plants, Kaylie A. Austin
MSU Graduate Theses
One of the most effective methods of reducing pesticide application in vineyards is breeding hybrid varieties for disease resistance. The new varieties must be assessed for disease resistance and viticultural traits. This thesis focuses on seven new varieties from a cross of ‘Norton’ and ‘Cabernet Sauvignon’. ‘Norton’ was chosen because of its disease resistance and cold hardiness. ‘Cabernet Sauvignon’ was selected because of its high-quality wine making berries. The cross was made in 2005, seven were selected in 2011, and evaluation began in 2016. Using Botrytis cinerea as a model pathogen, resistance was measured with an incidence rate and severity …
