Norton Blanc Grapevine Cultivar for Consistent Midwest Yields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new white grape variety that combines desirable viticultural and enological traits from red wine grape cultivars like 'Norton' and 'Cabernet Sauvignon', addressing issues such as bud break timing, disease resistance, yield consistency, and unique wine characteristics.
Innovation Solution
The development of 'Norton Blanc', a white grape variety resulting from a cross between 'Norton' and 'Cabernet Sauvignon', which exhibits late bud break, moderate disease resistance, consistent yield, and produces a unique light-bodied wine with balanced acidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cross between Norton and Cabernet Sauvignon is made to create a white grape variety, then unique wine characteristics and disease resistance are achieved, but the bud break timing becomes later compared to traditional white grape cultivars
Solution Approach 1:
The patent combines genetic material from two red wine grape cultivars (Norton and Cabernet Sauvignon) through controlled cross-pollination to create a new white grape variety. This merging of parental traits produces offspring that inherit disease resistance and cold hardiness from both parents while expressing white fruit color, achieving a unique combination of desirable characteristics that neither parent alone possesses.
2Productivity
If Norton Blanc is selected for consistent yield performance, then yield stability is improved, but the sugar content is lower compared to Norton
Solution Approach 1:
The patent documents specific physiological parameters of the Norton Blanc variety including its consistent yield range (11.2-13.2 lbs per vine), pH values (around 3.35), and sugar content (20.3-25.2 Brix). By establishing these parameter ranges through multi-year evaluation, the patent identifies the variety's optimal performance characteristics and suitable applications, particularly for regions where yield stability is prioritized over maximum sugar accumulation.
3Adaptability or versatility
If Norton Blanc is evaluated across multiple years and locations, then adaptability to Midwest conditions is improved, but the harvest timing becomes later compared to Norton
Solution Approach 1:
The patent describes preliminary multi-year evaluation trials conducted at the Missouri State Fruit Experiment Station and other Midwest locations to assess Norton Blanc's adaptability before recommending it for commercial production. These preliminary actions include evaluating bud break dates, flowering timing, veraison, and harvest dates across different years and sites, allowing growers to plan vineyard management and harvest logistics in advance based on the variety's documented performance patterns.
