Seedless Grapevine BLOMG03 Disease Tolerance Hybridization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grapevine varieties lack tolerance to Erysiphe necator, a major disease affecting Vitis vinifera, which can lead to significant yield loss and reduced fruit quality.
Innovation Solution
The development of a new seedless grapevine variety, 'BLOMG03', which exhibits tolerance to Erysiphe necator through hybridization between '12-3-73' and 'RS12-1-158', resulting in medium-sized, white, globose berries with excellent muscat flavor and crunchy texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing grapevine varieties are cultivated, then fruit production is achieved, but they lack tolerance to Erysiphe necator leading to yield loss and reduced quality
Solution Approach 1:
The patent applies parameter changes by developing a new grapevine variety with altered genetic parameters that confer tolerance to Erysiphe necator while maintaining or improving productivity. The hybridization between '12-3-73' and 'RS12-1-158' creates a new genetic combination with desired traits including disease tolerance and high fertility index of 1.3
2Reliability
If seedless grape varieties are developed, then fruit quality is improved, but disease resistance is compromised
Solution Approach 1:
The patent applies composite materials principle by creating a composite genetic structure through hybridization that combines traits from both parent varieties. The new variety 'BLOMG03' integrates seedlessness from one parent with disease tolerance from the other, achieving a composite genotype that expresses both desirable traits simultaneously

AI summary
‘BLOMG03’ is a new and distinct grapevine plant with novel characteristics that include good fertility, naturally loose bunches and is tolerance to Erysiphe necator, which is one of the main diseases of this species. The berries produced by ‘BLOMG03’ are white and seedless with a crunchy texture and muscat flavor and no detectable seed traces. The berries produced by ‘BLOMG03’ are medium, weighing 5.3 g/berry on average, and harvested in early July in Murcia Region (Spain).
