VOLTURNIS Grapevine Hybrid for Downy Mildew Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grape varieties lack resistance to downy mildew and often have susceptibility to powdery mildew, and they may not be well-suited to the specific climate and growing conditions of temperate regions with average yearly temperatures around 13°C and significant rainfall, such as North-Eastern Italy.
Innovation Solution
The 'VOLTURNIS' grape variety, resulting from a hybridization of 99-1-48 and Pinot Noir, exhibits high vigor, semi-erect growth habit, circular leaf shape, medium to large bunch density, and resistance to downy mildew, making it suitable for temperate regions like North-Eastern Italy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing grape varieties are used, then they may have good adaptability to certain climates, but they lack resistance to downy mildew and are susceptible to powdery mildew
Solution Approach 1:
The patent applies hybridization to create a composite genetic structure by crossing two different grapevine varieties (99-1-48 and Pinot Noir). This combines the disease resistance traits from one parent with the climate adaptability and fruit quality traits from the other, resulting in a new variety that exhibits both downy mildew resistance and powdery mildew tolerance while maintaining adaptability to temperate climates with significant rainfall.
2Reliability
If grape varieties are selected for disease resistance, then reliability improves, but productivity and consistent fruit production may be compromised
Solution Approach 1:
The patent merges multiple desirable traits from different parent varieties into a single new variety. The hybridization process combines the disease resistance characteristics (downy mildew resistance and powdery mildew tolerance) with high vigor, strong growth habit, and consistent fruit production capability. This merging of traits ensures that the new variety achieves both reliability through disease resistance and productivity through consistent annual fruit yields.

AI summary
A new grape variety distinguished by its high vigour with a semi-erect growth habit, low-medium blistering of the upper side of the leaf blade, circular shaped leaves, fruit clusters of medium or medium-large bunch density with 3-4 wings, medium harvesting time (early September in northeastern Italy), and resistance to downy mildew.
