Sheegene-2 Grapevine Early Maturity Hybridization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grape varieties, such as Thompson Seedless, have a delayed maturity that complicates commercial harvesting and shipping in the San Joaquin Valley of Central California, as they typically mature after the optimal window for early July harvesting.
Innovation Solution
The development of the Sheegene-2 grapevine, a hybrid of Princess and Red Globe, which produces large, green-colored seedless grapes that mature at least ten to fourteen days earlier than Thompson Seedless, ensuring timely harvesting and shipment in late July.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If Thompson Seedless grape variety is used, then large green-colored seedless grapes are produced, but maturity is delayed beyond the optimal commercial harvesting window
Solution Approach 1:
The patent applies parameter changes by hybridizing Princess and Red Globe grape varieties to create Sheegene-2, which changes the ripening time parameter while maintaining other quality parameters. The new variety matures 10-14 days earlier than Thompson Seedless, shifting the maturity timeline to align with optimal commercial harvesting windows in late July, while preserving flavor quality and handling characteristics.
2Loss of time
If early maturing varieties are selected, then harvesting timing is improved, but grape size and quality may be compromised
Solution Approach 1:
The patent applies composite materials by creating a hybrid grape variety that combines genetic material from Princess and Red Globe parents. This composite genetic structure produces Sheegene-2 grapes that exhibit early maturing characteristics (10-14 days ahead of Thompson Seedless) while maintaining large grape size, green coloration, and seedless properties, thus achieving multiple desirable traits simultaneously.
3Stability of the object's composition
If Thompson Seedless is used for commercial production, then consistent grape characteristics are maintained, but the delayed maturity complicates harvesting and shipping logistics
Solution Approach 1:
The patent applies parameter changes by modifying the maturity timing parameter of the grape variety through hybridization. Sheegene-2 maintains the consistent green color, seedless characteristic, and large grape size of Thompson Seedless, while changing the ripening time parameter to mature in late July, thereby improving harvesting efficiency and aligning with optimal shipping windows without sacrificing compositional consistency.

AI summary
A new and distinct variety of grapevine characterized by the production of large, green-colored seedless grapes that mature in late July, at least ten to fourteen days earlier than Thompson Seedless (unpatented) when grown in the San Joaquin Valley of Central California. The grapes of this new variety are produced on strong woody stems and branches and are well adapted to commercial handling.
