Hwangok Apple Tree Fruit Attributes and Clonal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of apple tree that can be propagated clonally and offers unique fruit attributes, such as size, shape, and color, which are not adequately met by existing varieties.
Innovation Solution
The 'Hwangok' apple tree, resulting from a planned cross between 'Kogetsu' and 'Yataka', is propagated using traditional grafting techniques and exhibits stable traits, with fruit characteristics including a globose shape, medium size, and a yellow-green surface with variable red patches, differing from its parents and other comparators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional apple varieties are used, then fruit production is established, but fruit attributes (size, shape, color) are limited and do not meet unique requirements
Solution Approach 1:
The patent applies parameter changes by creating a new apple variety with modified fruit characteristics including globose shape, medium size, and yellow-green surface with red patches. The breeding process altered multiple parameters simultaneously (shape, size, color) to achieve the desired unique fruit attributes while maintaining genetic stability through clonal propagation.
2Adaptability or versatility
If new variety is developed through cross-breeding, then unique fruit attributes are achieved, but genetic variations may occur in clonal propagations
Solution Approach 1:
The patent employs copying through asexual propagation methods (grafting, budding, or layering) to replicate the selected apple plant exactly. This creates genetically identical copies that preserve the unique fruit attributes achieved through cross-breeding while eliminating genetic variations, ensuring trait stability across multiple generations.
3Adaptability or versatility
If cross-breeding is performed to achieve distinctive fruit characteristics, then fruit shape and color are improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by conducting the cross-breeding between 'Kogetsu' and 'Yataka' varieties in advance to develop the desired fruit characteristics, then selecting and stabilizing the superior offspring before large-scale propagation. This preliminary breeding and selection phase ensures that the unique fruit attributes are established before committing to extensive clonal multiplication, reducing overall breeding time.
4Stability of the object's composition
If clonal propagation is used to maintain trait stability, then genetic consistency is achieved, but propagation efficiency may be limited
Solution Approach 1:
The patent applies universality by employing multiple asexual propagation methods (grafting, budding, and layering) for the same apple variety. This multi-functional approach allows selection of the most efficient method for different propagation contexts, maintaining genetic consistency while optimizing propagation efficiency based on specific needs and conditions.
