Sheegene-18 Grapevine Hybridization for Seedless Green Fruit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of Vitis vinifera that produces medium-sized, green-colored seedless grapes with good flavor, which matures early enough for harvesting and shipment in the San Joaquin Valley of Central California, as existing varieties either produce white or large red seeded grapes.
Innovation Solution
The 'Sheegene-18' grapevine, resulting from the hybridization of 'Princess' and 'Red Globe', produces medium-sized green-colored seedless grapes with excellent flavor, maturing in early September and exhibiting desirable traits such as very good productivity and shipping qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing grape varieties are used, then white or large red seeded grapes are produced, but the need for medium-sized green seedless grapes with early maturation is not met
Solution Approach 1:
The patent combines the green color trait from the 'Princess' variety with the seedless characteristic from the 'Red Globe' variety through hybridization, creating a new variety that simultaneously exhibits both desired traits along with medium size and early maturation
2Loss of time
If early maturation is achieved, then harvesting and shipment timing is improved, but grape size and flavor quality must be maintained
Solution Approach 1:
The hybridization process alters the genetic parameters of the parent varieties to achieve a new combination that matures four to five weeks earlier than 'Thompson Seedless' while simultaneously producing medium-sized grapes with very good flavor, thereby changing the developmental timeline without sacrificing quality

AI summary
A new and distinct variety of grapevine characterized by the production of medium, green-colored seedless grapes that mature in early September 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.
