SORÉLI Grapevine Cold and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grapevine varieties lack sufficient resistance to cold temperatures and tolerance to downy mildew and powdery mildew, limiting their adaptability and productivity in temperate regions with fluctuating climates.
Innovation Solution
The development of the 'SORÉLI' grapevine variety, resulting from a controlled breeding program, which combines resistance to cold temperatures below -20°C, resistance to downy mildew, and tolerance to powdery mildew, characterized by medium-strong vigor, horizontal growth habit, and early maturity, making it suitable for temperate regions like North-Eastern Italy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional grapevine varieties are used, then fruit production is maintained, but resistance to cold temperatures and tolerance to downy mildew and powdery mildew are insufficient
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific genetic parameters related to cold resistance and disease tolerance. The new variety 'SORÉLI' was developed by changing the genetic parameters of the grapevine through controlled crossing of parent varieties with desirable traits, resulting in a plant that exhibits superior resistance to cold temperatures (below -20°C) and tolerance to downy mildew and powdery mildew compared to conventional varieties.
Solution Approach 2:
The patent employs composite materials principle in the context of composite genetic makeup. The new grapevine variety combines genetic material from different parent varieties (Vitis vinifera 'Tocai Friulano' and Vitis cross '20/3') to create a composite genome that integrates multiple desirable characteristics: cold resistance, disease tolerance, and fruit production capabilities, thereby achieving superior adaptability to temperate regions.
2Reliability
If grapevine varieties with improved disease resistance are developed, then reliability increases, but breeding complexity and time requirements increase
Solution Approach 1:
The patent applies preliminary action by conducting breeding work and selecting parent varieties in advance before the actual fruit production phase. The controlled crossing of parent varieties and initial selection of the new variety 'SORÉLI' were performed beforehand, allowing the variety to be developed and tested for disease resistance before being deployed for commercial production, thus simplifying the overall breeding program structure.
Solution Approach 2:
The patent uses an intermediary approach by employing controlled breeding programs as a mediator between the desired disease resistance traits and the final grapevine variety. The breeding program acts as an intermediary system that systematically combines genetic material from resistant parent varieties, filters through multiple generations, and produces a stable variety with confirmed disease resistance, thereby managing the complexity of trait integration.
3Adaptability or versatility
If new grapevine varieties are bred with specific resistance characteristics, then adaptability to specific regions improves, but genetic diversity and traditional variety characteristics may be reduced
Solution Approach 1:
The patent applies local quality by developing a grapevine variety specifically adapted to the local conditions of temperate regions with cold winters and fluctuating climates. The new variety 'SORÉLI' exhibits localized adaptation characteristics including resistance to cold temperatures (below -20°C) and specific disease tolerances that are particularly relevant to temperate zones, while maintaining general viability in other suitable environments through its medium-strong vigor and horizontal growth habit.

AI summary
A new and distinct variety of grapevine, primarily suited to the growing conditions of the temperate regions, and characterized by its medium-strong vigor; horizontal growth habit; medium-sized, wedge-shaped to circular-shaped leaves; very low to low weight berry clusters; berries with slightly firm flesh, neutral taste, and no flesh coloration; primarily used for wine; and resistance to winter temperatures (to −24° C.), resistance to downy mildew, and tolerance to powdery mildew.
