EJG Two Grapevine Hybrid for Distinct Herbal Mint Flavor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grapevine varieties, such as Muscat blanc and Symphony, lack distinct sweet herbal and mint flavors, and exhibit incomplete seed development, resulting in seedless berries, which limits their suitability for specific wine production and flavor profiles.
Innovation Solution
The development of the 'EJG Two' grapevine, a Vitis interspecific hybrid, which produces medium-large grapes with normal seed development, distinct sweet herbal and mint flavors, and is suitable for white wine production, achieved through hand pollination and asexual propagation, resulting in a unique DNA fingerprint different from existing varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If current grapevine varieties (Muscat blanc, Symphony) are used for wine production, then they produce seedless berries with incomplete seed development, but they lack distinct sweet herbal and mint flavors required for specific wine profiles
Solution Approach 1:
The patent changes the genetic parameters of the grapevine by creating a new interspecific hybrid variety (EJG Two) that combines traits from different parent varieties. This new variety exhibits complete seed development while simultaneously producing the desired sweet herbal and mint flavors, thus resolving the contradiction between seed development quantity and flavor profile reliability.
Solution Approach 2:
The grapevine variety EJG Two acts as a composite genetic material, combining desirable traits from multiple parent varieties including complete seed development from one parent and distinct sweet herbal/mint flavors from another parent. This composite approach allows the new variety to simultaneously achieve both complete seed development and reliable flavor profiles.
2Reliability
If hand pollination is performed to create new grapevine varieties, then distinct flavor profiles and normal seed development can be achieved, but the breeding process requires significant time and manual intervention
Solution Approach 1:
The patent applies preliminary action by performing controlled hand pollination during the flowering stage to deliberately create the desired genetic combination. This preliminary genetic intervention ensures that the resulting variety (EJG Two) will consistently produce the target flavor profile and seed development characteristics in future generations, eliminating the need for repeated breeding cycles.
3Stability of the object's composition
If asexually propagated vines are planted to ensure true-to-type replication, then genetic consistency is maintained, but the initial establishment and propagation process requires additional time and resources
Solution Approach 1:
The patent uses asexual propagation through hardwood cuttings to create genetic copies of the selected superior vine. This copying method ensures that all propagated vines are true-to-type and will produce identical flavor profiles, seed development characteristics, and other desirable traits, thereby maintaining genetic consistency while using a standard horticultural technique.
