The Identification Of Interspecific Hybrids Between Jaeger 70 X Vignoles Grapes Using Ssr Markers, Carl William Knuckles Iv
The Identification Of Interspecific Hybrids Between Jaeger 70 X Vignoles Grapes Using Ssr Markers, Carl William Knuckles Iv
MSU Graduate Theses
Jaeger 70 cultivar is an interspecific hybrid of Vitis linececumii x Vitis rupestris, with an interesting past. It was created by Hermann Jaeger of Neosho, MO, who is most notable for saving the French wine industry by developing phylloxera resistant rootstocks in the mid-1800s. Traditionally the Jaeger 70 variety has been grafted to French wine grape cultivars to impart disease resistance and cold hardiness while retaining desirable wine characteristics. One interesting characteristic of Jaeger 70 is that it is a female-only plant, allowing for many interesting areas of study. Vitis interspecific hybrid Vignoles, is a cold hardy cultivar of largely …
An Assessment Of Seven New Grape Varieties And A Study Of Grapevine Vein Clearing Virus In Native Vitaceae Plants, Kaylie A. Austin
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 …
