BN5-4 Grapevine Disease Resistance and Wine Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grapevine varieties face challenges in sub-tropical environments due to susceptibility to bacterial and fungal diseases, with existing varieties often lacking robust resistance and suitable characteristics for wine production.
Innovation Solution
The development of a new grapevine variety, 'BN5-4', which is self-fertile, vigorously growing, and resistant to bacterial Pierce's disease and various fungal diseases, with dark-purple berries suitable for producing acceptable dry light red wine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing grapevine varieties are cultivated in sub-tropical environments, then they can produce fruit, but they are susceptible to bacterial and fungal diseases
Solution Approach 1:
The patent applies parameter changes by developing a new grapevine variety with fundamentally different genetic parameters that confer inherent resistance to bacterial and fungal diseases. The variety 'BN5-4' was bred to possess disease-resistant characteristics that are genetically encoded, allowing it to thrive in sub-tropical environments where existing varieties succumb to pathogens like Pierce's disease and fungal infections.
2Reliability
If grapevine varieties are bred for disease resistance, then they can survive in sub-tropical environments, but they may lack suitable characteristics for wine production
Solution Approach 1:
The patent applies universality by creating a grapevine variety that simultaneously performs multiple functions: it is resistant to bacterial and fungal diseases for survival in sub-tropical environments, while also producing fruit with suitable characteristics for wine production. The variety 'BN5-4' integrates both disease resistance and wine-making quality in a single cultivar, eliminating the need to choose between survival and productivity.
3Productivity
If existing grapevine varieties are cultivated in humid sub-tropical conditions, then they can grow, but they suffer from poor disease resistance and reduced durability
Solution Approach 1:
The patent applies parameter changes by breeding a grapevine variety with genetically determined parameters that enable both vigorous growth and long-term durability in humid sub-tropical conditions. The variety 'BN5-4' maintains high productivity while exhibiting exceptional durability, remaining healthy and productive for extended periods despite the challenging humid environment that typically reduces vine lifespan and performance.

AI summary
A new and distinct hybrid wine grapevine plant named ‘BN5-4’, characterized by the following unique combination of characteristics: Very vigorous with extremely high disease resistance in the southeastern United States, including resistance to bacterial Pierce's disease and a host of fungal diseases. Average- to high-yielding vines, with dark, purple-skinned, seeded berries. Wine from the variety may be produced to be light red with a pleasant character and low residual sugar, or with a foxy character.
