Seedless Grapevine Cultivar SV22-88e-124 with Amber Berries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grapevine cultivars lack a combination of highly flavored, crisp-textured, and seedless berries with unique flavor profiles, such as the spun sugar flavor, which are not adequately addressed by existing varieties like '14-44-248', 'Jupiter', and 'IFG Seven'.
Innovation Solution
The development of a new grapevine cultivar 'SV22-88e-124' resulting from a cross between '14-44-248' and 'Jupiter', characterized by elliptical, seedless, amber-colored berries with a spun sugar flavor and crisp texture, propagated using cuttings and grafted onto 'Freedom' rootstock, retaining distinctive characteristics through successive asexual propagations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing grapevine cultivars like '14-44-248', 'Jupiter', and 'IFG Seven' are used, then certain desirable traits are present, but none achieve the combination of seedless berries with highly flavored, crisp-textured fruit and unique flavor profiles
Solution Approach 1:
The patent merges the seedless trait from parent '14-44-248' with the muscat flavor and aromatic qualities from parent 'Jupiter' through controlled cross-breeding. The resulting cultivar 'SV22-88e-124' combines these parental characteristics to achieve both seedlessness and enhanced flavor complexity, resolving the contradiction between reliable seedless production and diverse flavor profiles.
Solution Approach 2:
The grapevine cultivar represents a composite genetic material combining traits from two distinct parent varieties. The heterozygous genetic composition creates a new phenotype that exhibits both the seedless characteristic (from one parent) and the enhanced aromatic, muscat flavor profile (from the other parent), achieving a composite trait package not present in either parent alone.
2Shape
If grapevine '14-44-248' is used as a parent, then seedless berries can be produced, but the berries are ellipsoidal shaped, very large seeded (not seedless), and reddish black in color
Solution Approach 1:
The invention applies local quality by modifying specific berry characteristics (seed presence, color, shape) while maintaining the overall ellipsoidal form. The new cultivar retains the ellipsoidal shape from parent '14-44-248' but eliminates seeds and changes color to amber, achieving localized trait improvements without completely redesigning the berry morphology.
3Adaptability or versatility
If grapevine 'Jupiter' is used as a parent, then muscat flavor is achieved, but the berries are reddish black and do not have the spun sugar flavor profile
Solution Approach 1:
The invention changes the color parameter from reddish black (parent 'Jupiter') to amber in the offspring 'SV22-88e-124'. This parameter change occurs alongside the development of the unique spun sugar flavor profile, demonstrating how genetic recombination can simultaneously modify multiple berry parameters (color, flavor, seed presence) to create a superior cultivar.
4Shape
If commercial cultivar 'IFG Seven' is used, then green colored berries are produced, but the berry firmness is soft-medium rather than crisp
Solution Approach 1:
Instead of accepting the soft-medium firmness associated with green berries (as in 'IFG Seven'), the invention inverts this relationship by producing amber-colored berries with crisp firmness. The new cultivar 'SV22-88e-124' demonstrates that berry color and firmness are not strictly correlated, achieving an unusual combination of amber color and crisp texture that differs from both parents and commercial varieties.

AI summary
A new and distinct variety of grapevine plant named ‘SV22-88e-124’ particularly characterized by its amber colored berries with sweet, aromatic flavor similar to spun sugar. Additionally, berries of the new cultivar are very responsive to applications of exogenous gibberellic acid, producing looser clusters with larger berries compared to untreated clusters.
