Seedless Grapevine Cultivar SV34-150-338 Storage and Flavor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current green grape cultivars, such as 'Autumn King', have undesirable seed traces and flavor profiles, and 'Princess' berries brown internally during cold storage, while 'Sugrathirtyfive' has a muscat flavor that may not be desirable for all markets, indicating a need for a late-ripening, seedless table grape with superior fruit characteristics.
Innovation Solution
The development of the new grapevine cultivar 'SV34-150-338', resulting from a cross between 'SV30-23-590' and 'Princess', which features yellowish-green, firm, large, sweet berries with neutral flavor, and improved storage qualities, including no browning during cold storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If green grape cultivar 'Autumn King' is used, then late ripening characteristic is achieved, but seed traces are large and objectionable when eaten
Solution Approach 1:
The patent applies the extraction principle by developing a seedless grape variety through tissue culture and selective breeding. The new cultivar 'SV34-150-338' has been bred to eliminate seeds entirely, extracting the undesirable seed component from the fruit while preserving the late-ripening characteristic and other desirable traits of the parent varieties.
2Shape
If grapevine cultivar 'Princess' is used, then yellow berry color is achieved, but berries brown internally while in cold storage
Solution Approach 1:
The patent applies local quality by developing a cultivar with differentiated characteristics in various parts of the fruit. The new grape variety maintains uniform yellowish-green coloration throughout the berry flesh and skin, preventing the internal browning that occurs in the 'Princess' cultivar during cold storage, while preserving the desirable color properties.
3Object-generated harmful factors
If grapevine cultivar 'Sugrathirtyfive' is used, then sweet flavor is achieved, but muscat flavor may not be desirable for all markets
Solution Approach 1:
The patent applies universality by developing a grape cultivar with a neutral flavor profile that appeals to broader market segments. The new variety 'SV34-150-338' produces berries with a mild, non-muscat sweetness that can be accepted by consumers with varying flavor preferences, making it adaptable to multiple market applications including fresh consumption, processing, and regional preferences.
