EJG One Grapevine Breeding for Wine Flavor and Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grapevine varieties lack a distinct combination of fruity and muscat flavor, deep red color, and suitable characteristics for wine production, particularly in terms of ripening time, cluster size, and shoot attitude, which are not adequately met by existing commercially grown wine grape varieties.
Innovation Solution
The development of the 'EJG One' grapevine, resulting from hand pollination of 'Aspiran Bouschet' and 'Muscat of Alexandria', which exhibits medium-small dense clusters of small, deeply colored black grapes with red flesh and strong muscat flavor, suitable for wine production, and distinguished by its unique DNA fingerprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing commercially grown wine grape varieties are used, then wine production can proceed with current varieties, but the wine lacks a distinct combination of fruity and muscat flavor with deep red color
Solution Approach 1:
The patent combines the desirable traits of two different grape varieties through controlled hand pollination: the deep color and body from 'Aspiran Bouschet' and the muscat flavor from 'Muscat of Alexandria'. This merging of parental characteristics produces a new variety that exhibits both fruity and muscat flavors with deep red color, resolving the contradiction between reliable wine production and distinctive flavor profile.
Solution Approach 2:
The new grape variety represents a composite genetic material combining alleles from both parent varieties. The resulting grapevine possesses a unique genetic composition that expresses both the color intensity of one parent and the aromatic characteristics of the other, creating a composite phenotype that neither parent alone could achieve.
2Loss of time
If earlier ripening varieties are used, then harvest can occur earlier, but the variety lacks the desired cluster size and shoot attitude characteristics
Solution Approach 1:
The patent achieves a later ripening schedule (September-October) compared to earlier varieties (July-August) while simultaneously improving cluster size and shoot attitude. This parameter change in ripening time is coupled with changes in cluster dimensions and shoot morphology, demonstrating that multiple desirable parameters can be optimized together through variety selection and breeding rather than requiring trade-offs.
3Volume of moving object
If varieties with different cluster sizes are selected, then cluster size can be optimized, but the flavor profile and color characteristics may be compromised
Solution Approach 1:
The patent merges the large cluster size trait with the deep color and muscat flavor traits in a single variety. The resulting 'EJG One' grapevine produces clusters that are larger than many traditional varieties while maintaining the deep red color and complex flavor profile, eliminating the need to trade off cluster size against quality characteristics.
