IFG Thirty-five Grapevine Seedless Berries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grapevine varieties face challenges such as seeded berries, uneven ripening, thicker skin, and a lesser muscat flavor, which affect their market appeal and handling characteristics.
Innovation Solution
The development of the grapevine 'IFG Thirty-five' addresses these issues by producing naturally seedless, elliptic berries with a strong muscat flavor, thin skin, and uniform size, which ripen earlier and are less prone to bruising, achieved through a hand-pollinated cross of specific seedless selections and subsequent asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If grapevine varieties produce seeded berries with thicker skin, then they have better structural integrity and disease resistance, but they have lower market appeal and require more handling effort
Solution Approach 1:
The patent applies parameter changes by selecting for specific genetic traits that modify berry characteristics - achieving seedlessness through controlled pollination and selection, while simultaneously developing thinner skin through breeding. This resolves the contradiction by changing the genetic parameters of the grapevine to produce berries that are both seedless and have desirable skin thickness for handling.
2Duration of action of moving object
If grapevine varieties have uneven ripening and later maturity, then they have extended growing season, but they have reduced market appeal and increased labor requirements
Solution Approach 1:
The patent changes the ripening parameter by selecting parent varieties with complementary ripening characteristics and using controlled pollination to produce offspring with improved ripening uniformity. The resulting 'IFG Thirty-five' variety exhibits more synchronized ripening compared to its parents, reducing harvest labor while maintaining an appropriate growing season duration.
3Quantity of substance
If grapevine varieties produce smaller oval berries, then they have higher yield per cluster, but they have less market appeal and lower price premium
Solution Approach 1:
The patent applies parameter changes by selecting for larger berry size and more elliptic shape through controlled breeding. The 'IFG Thirty-five' variety produces berries that are larger and more elliptic than its parents, combining desirable market characteristics with adequate yield potential.
4Ease of manufacture
If grapevine varieties have stronger muscat flavor, then they have higher market appeal, but they may have reduced adaptability to different growing conditions
Solution Approach 1:
The patent applies preliminary action by conducting controlled pollination and extensive field testing across multiple locations and conditions before releasing the variety. The 'IFG Thirty-five' variety was evaluated for adaptability to different growing conditions while maintaining its muscat flavor characteristics, ensuring both market appeal and versatility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
IFG Thirty-five offers improved berry characteristics, including larger size, earlier ripening, thinner skin, and a more pronounced muscat flavor, enhancing its marketability and handling properties compared to similar varieties like 'Italia' and its parental lines.
Implementation Method 1
Berries are highly responsive to Gibberellic acid applications to increase berry size

AI summary
This invention is a new and distinct grapevine variety denominated ‘IFG Thirty-five’. The new grapevine is characterized by producing naturally large size elliptic seedless berries having a strong muscat flavor, very thin skin and which ripens in mid-season. Berries are borne on medium size clusters which may require low rates of gibberellin to thin.
