Sugrafiftythree Grapevine Early Ripening Firm Berry Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing grapevine varieties lack a distinct, early-ripening, dark-red berry variety with broad elliptic shape and firm texture, which are desirable for fresh market and storage quality.
Innovation Solution
A new grapevine variety, 'Sugrafiftythree', is developed through controlled hybridization, characterized by broad elliptic, dark-red berries that ripen early, are firm, and exhibit excellent storage quality, differing from its parents in berry color and ripening time, and maintaining these traits through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing grapevine varieties are used, then production is maintained, but berry color, shape, and ripening time do not meet market requirements for early-ripening dark-red berries with firm texture
Solution Approach 1:
The patent applies parameter changes by developing a new grape variety with specific berry characteristics (dark-red color, broad elliptic shape, early ripening) through controlled hybridization. The new variety 'Sugrafiftythree' exhibits distinct parameter differences from parent varieties including berry color (red vs green), shape (broad elliptic vs round), and ripening time (early June vs late August), directly addressing the market demand for early-ripening dark-red berries with firm texture
2Reliability
If new variety traits are achieved through hybridization, then berry quality and ripening time are improved, but breeding complexity and time investment increase
Solution Approach 1:
The patent applies preliminary action by performing controlled hybridization between specifically selected parent varieties ('04006-199-045' and 'GR363W') to pre-establish the desired traits in the offspring. The breeding process was systematically conducted with parent selection, controlled crossing in April 2014, and subsequent propagation through cuttings and grafting, demonstrating a planned approach to achieve reliable storage quality and early ripening characteristics
3Stability of the object's composition
If asexual propagation is used to maintain variety characteristics, then trait consistency is improved, but propagation time and labor requirements increase
Solution Approach 1:
The patent applies copying through asexual propagation methods (hardwood cuttings and grafting) to reproduce the new variety 'Sugrafiftythree' with identical genetic characteristics. The variety was first asexually propagated in December 2016 using hardwood cuttings, and subsequent propagations have maintained consistent traits including broad elliptic shape, dark-red color, and early ripening, ensuring trait stability across multiple generations without sexual recombination
