IFG Thirty-one Grapevine Hybrid Flavor and Texture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Previous interspecific grape varieties introduced to enhance hardiness, disease, and insect resistance, and incorporate aromatic flavors into Vitis vinifera species have limited commercial success due to small fruit size, large seed traces, slipskin texture, or lack of firmness.
Innovation Solution
The development of the grapevine variety 'IFG Thirty-one', which combines a unique labrusca flavor with seedlessness and good skin adhesion, characterized by small purple-black berries, moderate productivity, and a vigorous growth habit, addresses these limitations by offering a distinct flavor profile and improved fruit characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interspecific grape varieties are introduced to enhance hardiness, disease and insect resistance, and incorporate aromatic flavors into Vitis vinifera species, then resistance to environmental stresses and pests is improved, but fruit size becomes small, seed traces become large, skin texture becomes slippery, and firmness is lacking
Solution Approach 1:
The patent combines multiple grape species (Vitis vinifera, Vitis labrusca, Vitis riparia) into a single interspecific hybrid variety that integrates the desirable traits of each parent species. The hybridization process merges the aromatic flavor and vinifera characteristics with the hardiness, disease resistance, and insect resistance of the American species, while simultaneously achieving adequate fruit size and firmness that were previously compromised in interspecific hybrids.
Solution Approach 2:
The grapevine variety represents a composite genetic material combining DNA from multiple species. This composite genetic structure provides both the resistance properties from Vitis riparia and Vitis labrusca and the fruit quality characteristics from Vitis vinifera, creating a unified variety that exhibits properties of all parent species without the traditional trade-offs.
2Object-generated harmful factors
If grape breeders use native American grape species to incorporate aromatic flavors into vinifera species, then flavor characteristics are improved, but fruit size becomes small and skin adhesion becomes poor
Solution Approach 1:
The patent merges the aromatic flavor characteristics from Vitis labrusca with the fruit size and skin adhesion properties from Vitis vinifera and Vitis riparia in a single hybrid variety. The resulting grape exhibits both the desired strong fruity labrusca flavor and adequate fruit size with proper skin-to-flesh adhesion, resolving the contradiction between flavor incorporation and fruit quality maintenance.

AI summary
This invention is a new and distinct grapevine variety denominated ‘IFG Thirty-one’. The new grapevine ‘IFG Thirty-one’ is characterized by producing small seedless, purple-black berries having a narrow ellipsoid shape with a unique strong fruity labrusca flavor reminiscent of artificial grape flavor. Fruits normally ripen early to mid-season about late July to early August near Delano Calif.
