Vanda SPCDW1501 Cultivar Color Stability via Mericloning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct Vanda cultivar that exhibits unique and stable characteristics such as specific color combinations and patterns on sepals and petals, which are not observed under all environmental conditions without variance in genotype.
Innovation Solution
The cultivar 'SPCDW1501' is developed through planned breeding, combining the proprietary seed parent Vanda 'T131B' and pollen parent Vanda 'T9112', and is characterized by sepals and petals with a unique light purple and blue color combination, heavily dotted and blotched with dark purple, and a very dark purple central lobe of the labellum, maintained through six generations of asexual reproduction by mericloning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a new Vanda cultivar is developed through planned breeding to achieve unique color combinations and patterns, then the aesthetic value and distinctiveness are improved, but the stability of these characteristics across different environmental conditions cannot be guaranteed
Solution Approach 1:
The patent applies preliminary action by conducting confidential testing and propagation before commercial release, assessing stability of unique characteristics through six generations of asexual reproduction. This preliminary validation ensures that the distinctive color combinations and patterns remain stable under controlled conditions before the cultivar is introduced to the market, thereby resolving the contradiction between achieving distinctiveness and ensuring reliability.
2Stability of the object's composition
If the cultivar is propagated through asexual reproduction by mericloning to maintain genetic stability, then the genotype consistency is improved, but the adaptability to different environmental conditions may be limited
Solution Approach 1:
The patent uses copying through asexual reproduction by mericloning to produce genetically identical copies of the selected plant. This method maintains the unique color combination of light purple and blue with dark purple dotting and blotching, as well as the very dark purple labellum central lobe, across all propagated plants. The copying process ensures genotype consistency while the preliminary environmental testing demonstrates the cultivar's adaptability to controlled greenhouse conditions and USDA Zones 11 and 12.
