Vitis aestivalis-derived ‘Norton’ grapes are a popular cultivar with vineyards in midwestern and eastern United States due to high disease resistance and cold temperature hardiness.
VitisGen2 researcher Chin-Feng Hwang and his team from Missouri State University recently published a new article in Fruit Research on fruit chemistry in Vitis aestivalis-derived ‘Norton’ grapes.
The article describes how acidity and tannin concentrations of this popular grape variety vary from commercial and consumer expectations of V. vinifera, and explore the genetic determinants of these components. The research team describes the identification of several new QTLs for these traits which may assist with improved hybrid cultivar breeding through marker-assisted selection.
