SV35-206-150 Grapevine Cultivar for Large Seedless Berries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing green, seedless table grape cultivars lack superior fruit characteristics and productivity, particularly in terms of berry size, seed trace length, ripening time, and response to gibberellic acid applications.
Innovation Solution
Development of a new grapevine cultivar 'SV35-206-150', resulting from a cross between 'SV29-45-20' and 'SV21-66-226', with large, green berries that are seedless, firm, and responsive to gibberellic acid, ripening in mid-season, and exhibiting high sugar content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing green, seedless table grape cultivars are used, then they are available for cultivation, but they lack superior fruit characteristics and productivity
Solution Approach 1:
The patent applies parameter changes by crossing two parent cultivars with different characteristics to produce offspring with optimized parameters: 'SV29-45-20' contributes seedlessness and green color, while 'SV21-66-226' contributes large berry size. The resulting 'SV35-206-150' combines these parameters to achieve superior productivity and fruit characteristics with consistent seedlessness and large berry size averaging 10g each.
2Quantity of substance
If green, seedless grape cultivars are selected, then they meet consumer preference for seedless fruit, but they have small berry size and limited productivity
Solution Approach 1:
The patent merges the desirable traits of two parent cultivars into a single superior variety. The female parent 'SV29-45-20' provides seedlessness and green skin, while the male parent 'SV21-66-226' provides large berry size. The hybrid 'SV35-206-150' combines these traits and adds superior productivity, achieving an average berry weight of 10g with high yield potential, thus merging quantity and quality improvements.
3Loss of time
If mid-season ripening is achieved, then market timing is optimized, but fruit characteristics may be compromised
Solution Approach 1:
The patent employs preliminary action through selective parental selection and controlled crossing to pre-determine the ripening characteristics of the offspring. By choosing parents with complementary traits and conducting the cross in May 2014 with controlled pollination and embryo culture, the resulting 'SV35-206-150' was pre-programmed to ripen in mid-season (mid-July to mid-August) while maintaining superior fruit quality including large size, seedlessness, and firm texture.
4Adaptability or versatility
If responsiveness to gibberellic acid is enhanced, then berry size can be increased, but natural berry size may be reduced
Solution Approach 1:
The patent applies dynamics by creating a cultivar with plastic berry size that can respond to environmental and hormonal factors. The 'SV35-206-150' grapevine exhibits dynamic berry development where natural berry size averages 10g, but the berries can be further enlarged through gibberellic acid applications and trunk girdling. This dynamic characteristic allows the same variety to produce different berry sizes depending on management practices, optimizing both natural and induced growth potential.
