ND054.27 Grape Hybrid for Cold Hardiness and Wine Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grape varieties used for high-quality wine production in northern regions of the United States are often susceptible to winter damage, and existing cold-hardy species produce wines with defects.
Innovation Solution
Development of the 'ND054.27' grape variety, a Vitis hybrid resulting from a cross between 'Frontenac Gris' and 'Adalmiina', exhibiting high cold hardiness, high yield, and resistance to diseases such as powdery mildew, downy mildew, and black rot, while producing well-balanced white wines with distinct flavor notes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V. vinifera varieties are cultivated in northern regions, then high-quality wine production is achieved, but winter cold hardiness is insufficient
Solution Approach 1:
The patent combines the cold hardiness traits from V. riparia and V. labrusca species with the wine quality traits from V. vinifera through controlled hybridization. The resulting 'ND054.27' cultivar merges these parental characteristics to achieve both winter survival capability and high-quality wine production in northern climates.
Solution Approach 2:
The grape cultivar represents a composite genetic material combining multiple Vitis species. The hybrid genome integrates adaptive genes for cold tolerance from hardy species while maintaining genes for wine quality from V. vinifera, creating a composite genetic structure that exhibits both desired traits simultaneously.
2Reliability
If wild Vitis species from colder regions are used, then winter hardiness is improved, but wine quality deteriorates with serious defects
Solution Approach 1:
The hybridization strategy applies local quality by selectively introducing specific genetic traits from wild species only where needed (cold hardiness and disease resistance) while maintaining the core wine quality genetics from V. vinifera. This targeted approach ensures cold tolerance is enhanced without compromising wine quality throughout the entire cultivar.
Solution Approach 2:
The patent uses V. vinifera as an intermediary parent in the hybridization scheme, crossing it with cold-hardy species to produce intermediates that then serve as parents for the final cultivar. This intermediary approach allows gradual integration of cold tolerance genes while maintaining wine quality, avoiding the direct use of wild species that would introduce wine defects.
3Reliability
If cold-hardy grape species are cultivated, then winter survival is improved, but disease resistance deteriorates
Solution Approach 1:
The resulting hybrid cultivar exhibits multi-functionality by simultaneously providing winter survival capability, disease resistance against multiple pathogens (powdery mildew, downy mildew, black rot), and high-quality wine production. This single cultivar performs multiple protective and productive functions that were previously分散 across different grape varieties.
