Scindapsus SUPHA10 Cultivar Stabilization via Asexual Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct cultivar of Scindapsus pictus that exhibits unique characteristics such as compact growth, exceptionally dark green foliage, and round broad leaf morphology, which are not adequately represented in existing varieties like Scindapsus pictus 'Exotica'.
Innovation Solution
The cultivar 'SUPHA10' is a chance mutation of Scindapsus pictus 'Exotica' that has been stabilized through asexual reproduction, showcasing a compact plant shape, exceptionally dark green foliage, and round broad leaf morphology, making it distinct from its parent variety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a distinct cultivar with compact growth and dark green foliage is developed through mutation, then unique ornamental characteristics are achieved, but stability of these characteristics across environmental conditions must be maintained
Solution Approach 1:
The patent applies parameter changes by selecting for specific morphological parameters (compact growth habit, leaf width, foliage color intensity) from a chance mutation. The cultivar 'SUPHA10' exhibits altered physical parameters compared to the parent variety, including reduced plant height, increased leaf width, and darker green foliage color, which are maintained through stable inheritance.
2Area of moving object
If wider leaves with darker color are produced through mutation, then visual distinctiveness is improved, but consistency of these traits through generations must be ensured
Solution Approach 1:
The patent applies segmentation by isolating and stabilizing specific mutant traits (wider leaves, darker color) as distinct segregating characteristics from the parent variety. Through asexual reproduction, these segmented traits are fixed and reproduced consistently across multiple generations, ensuring genetic stability of the unique features.
Solution Approach 2:
The patent applies copying through asexual reproduction methods that create genetically identical copies of the mutant plant. This ensures that the unique combination of wider leaves and darker coloration is precisely replicated in subsequent generations, maintaining trait consistency without genetic variation.
3Stability of the object's composition
If the cultivar is stabilized through asexual reproduction, then genetic uniformity is achieved, but adaptability to varying environmental conditions may be reduced
Solution Approach 1:
The patent applies preliminary action by stabilizing the genotype through asexual reproduction before exposing the cultivar to varying environmental conditions. The genetic uniformity is established in advance, allowing the cultivar to be tested and evaluated for phenotypic stability across different temperatures, day lengths, and light intensities, ensuring that environmental variations do not produce unwanted genetic changes.
