Grapevine Cultivar SV35-210-349 Breeding for Seedless Compact Clusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current commercial grape cultivars, such as 'Autumn King', lack desirable traits like late ripening, seedless, and compact fruit clusters, with berries that are either too large or have noticeable seeds, limiting their market appeal and horticultural performance.
Innovation Solution
The development of a new grapevine cultivar 'SV35-210-349', resulting from a cross between 'SV30-23-590' and 'SV22-104e-84', which exhibits late ripening, large sweet berries with neutral flavor, crisp texture, and compact clusters, addressing the shortcomings of existing varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If grapevine cultivar 'Autumn King' is used, then late ripening is achieved, but berry size is too large and clusters are loose
Solution Approach 1:
The patent applies parameter changes by selecting and breeding grapevine varieties with specific genetic traits that modify cluster architecture and berry size parameters. The cross between 'Chelan' and 'Autumn King' produced offspring with altered cluster compactness and berry size parameters while maintaining late ripening characteristics, demonstrating parameter optimization through selective breeding.
2Duration of action of stationary object
If grapevine cultivar 'Autumn King' is used, then late ripening is achieved, but berries have noticeable seeds
Solution Approach 1:
The patent applies the extraction principle by selectively removing the undesirable seed trait from the grapevine cultivar through controlled breeding. The cross between 'Chelan' and 'Autumn King' followed by selection of offspring with reduced seed visibility extracts the harmful seed characteristic while retaining the desirable late ripening trait, effectively taking out the unwanted feature.
3Object-generated harmful factors
If grapevine cultivar 'SV22-104e-84' is used, then seedless trait is achieved, but berry size is small
Solution Approach 1:
The patent applies the merging principle by combining two grapevine cultivars with complementary traits through controlled crossing. 'Chelan' contributes seedless characteristics while 'Autumn King' contributes larger berry size and late ripening, merging these distinct trait sets into a single offspring that exhibits all desirable characteristics simultaneously.
4Object-generated harmful factors
If grapevine cultivar 'SV22-104e-84' is used, then seedless trait is achieved, but clusters are loose
Solution Approach 1:
The patent applies the merging principle by combining 'Chelan' which provides seedless and compact cluster traits with 'Autumn King' which provides late ripening characteristics. The resulting offspring merges these parental traits to achieve seedlessness, compact clusters, and late ripening simultaneously.
