Sugrafiftyeight Grapevine Berry Shape and Ripening Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing grapevine varieties lack a distinct, early-ripening, large-sized, dark red, cylindrical berry with a fruity aroma and high brix content, which are desirable traits for fresh market and storage quality.
Innovation Solution
The development of the new grapevine variety 'Sugrafiftyeight' through controlled hybridization of 'GR285R' and 'GR162B', characterized by its unique berry shape, size, color, and brix level, achieved through asexual propagation using hardwood cuttings and grafting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing grapevine varieties are used, then cultivation is straightforward, but the berries lack desired characteristics of early ripening, large size, dark red color, cylindrical shape, and high brix content
Solution Approach 1:
The patent applies parameter changes by systematically selecting and crossing parent varieties with specific desirable traits (early ripening, large size, dark red color, cylindrical shape, high brix) to create a new variety that combines these parameters. The controlled hybridization process modifies the genetic parameters of the grapevine to achieve the desired berry characteristics that do not exist in current varieties.
Solution Approach 2:
The breeding program is segmented into distinct phases: selecting parent varieties, controlled hybridization, asexual propagation through cuttings, and field testing. This segmentation allows systematic development and verification of the new variety's characteristics, making the complex breeding process manageable and reproducible.
2Manufacturing precision
If new varieties are developed through controlled hybridization, then desired berry characteristics are achieved, but the development time and propagation complexity increase
Solution Approach 1:
The patent applies preliminary action by first selecting and preparing parent varieties with desired traits before conducting the hybridization. The parents are chosen and prepared in advance, and the controlled crossing is performed at the optimal time (April 2014), with asexual propagation initiated immediately after (December 2017). This preliminary planning and timing accelerates the overall development process.
Solution Approach 2:
The patent uses asexual propagation through hardwood cuttings and grafting to create copies of the new variety that faithfully reproduce its distinguishing characteristics. This copying method allows rapid multiplication of the new variety without the time required for sexual reproduction, maintaining genetic fidelity while accelerating propagation.
3Stability of the object's composition
If asexual propagation is used to maintain variety characteristics, then true-to-type propagation is achieved, but the propagation complexity and labor requirements increase
Solution Approach 1:
The patent employs asexual propagation methods (hardwood cuttings and grafting) that create genetic copies of the parent plant, ensuring the new variety's distinguishing characteristics are maintained true-to-type. This copying approach preserves the stable composition of the variety while enabling rapid multiplication.
Solution Approach 2:
The propagation system is designed to be self-sustaining, where the new variety can be propagated through its own cuttings and grafts without requiring external genetic intervention. This self-service capability maintains the variety's genetic stability while simplifying long-term propagation management.
