Kiwi Plant AC 501 022 Early Bud Burst and Storage Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing kiwi plant varieties lack a cultivar with strong plant vigor, early bud burst, and optimal characteristics for long storage and market suitability, such as 'AC 501 022', which is not addressed by current breeding programs.
Innovation Solution
A new kiwi plant variety 'AC 501 022' is developed through crossing 'Ac328.26' and 'A134.41', exhibiting strong plant vigor, early bud burst, and improved storage and market traits, distinguished from 'Soreli' and 'Ac328.26' by specific characteristics like sparse hair on young shoots and retuse leaf apex, and is asexually reproduced by grafting and in vitro propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing kiwi varieties are used, then cultivation is straightforward, but plant vigor is weak and harvest time is delayed
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in altered growth characteristics. The new variety 'AC 501 022' exhibits changed parameters including stronger plant vigor, earlier bud burst timing, and different fruit maturity characteristics compared to parent varieties, thereby resolving the contradiction between productivity and time loss.
2Loss of time
If kiwi varieties with early harvest are selected, then harvest time is reduced, but storage capability is compromised
Solution Approach 1:
The patent resolves this contradiction through parameter changes in the plant's physiological and biochemical characteristics. The new variety 'AC 501 022' has been bred to possess specific parameters that enable early harvest while simultaneously maintaining extended storage capability, unlike conventional varieties where early harvest correlates with poor storage performance.
3Productivity
If plant breeding is performed to achieve specific traits, then plant vigor and harvest time improve, but breeding complexity increases
Solution Approach 1:
The patent applies self-service by utilizing controlled cross-pollination between selected parent plants where the breeding process leverages natural reproductive mechanisms. The systematic selection of parent varieties with complementary traits and the use of standard horticultural propagation methods reduce the complexity that would otherwise arise from more intrusive genetic manipulation techniques.
