Interpretive Summary:

Technical Abstract: A new era of low-input, disease-resistant grape varieties is coming. Marker-assisted selection is allowing breeders to confidently incorporate several resistance genes into new varieties that will express a high level of resistance and offer the prospect of very significant reductions in fungicide applications. While today's vinifera grape growers rely heavily on fungicide use (up to 10 to 15 sprays per season, depending on location and management), these new varieties may require only two or three sprays per season. This article describes concepts for breeding and commercial vineyard management to enhance the durability of these new disease resistant grape varieties.
