JPD-001 Grapevine Seedless Trait and Berry Size Augmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grapevine varieties do not offer large, seedless, crisp, and non-cracking berries that mature effectively for commercial harvesting in the San Joaquin Valley of Central California, lacking desirable traits like enhanced berry size and seedlessness.
Innovation Solution
Development of a new grapevine variety, JPD-001, derived from Sheehan-Genetics 10-418 and 2-A Thompson Seedless, exhibiting larger natural berry size, crisper texture, and absence of lignified seeds, with improved responsiveness to berry size augmentation treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If existing grapevine varieties are used, then commercial harvesting is possible, but berry size is small and seed trace is noticeable
Solution Approach 1:
The invention extracts and eliminates the harmful element (lignified seed trace) from the grape berry through selective breeding. The JPD-001 variety naturally aborts seeds before lignification occurs, effectively removing the undesirable seed trace while maintaining commercial viability and large berry size.
Solution Approach 2:
The invention changes the developmental parameter of seed maturation by inducing early seed abortion through selective breeding. This parameter change prevents seed lignification entirely, resulting in seedless berries with no visible trace, while simultaneously allowing the berry flesh to develop to large commercial sizes.
2Volume of moving object
If berry size is increased through treatments, then yield is improved, but berry skin becomes prone to cracking
Solution Approach 1:
The JPD-001 variety exhibits self-service characteristics by naturally responding to berry size augmentation treatments with enhanced berry growth while simultaneously developing skin properties that resist cracking. The variety's inherent genetic makeup provides both the responsiveness to size enhancement and the structural integrity to prevent cracking during expansion.
3Manufacturing precision
If seedless characteristics are achieved, then consumer preference is improved, but seed development is incomplete
Solution Approach 1:
The invention extracts the harmful element (lignified seed trace) from the grape berry through selective breeding. The JPD-001 variety naturally aborts seeds before lignification occurs, effectively removing the undesirable seed trace while maintaining commercial viability and large berry size.
Solution Approach 2:
The selective breeding process performs preliminary action by establishing the seed abortion characteristic early in the variety's development history. This preliminary genetic modification ensures that all subsequent seed development is aborted before lignification, creating a stable seedless trait that is reliably transmitted to offspring.
