Tecoma Mnstabe Hybrid Yellow Orange Corolla Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Tecoma genus lacks a flower color variant that is distinctly yellow orange with interior and exterior corolla color differentiation, limiting diversity in ornamental horticulture.
Innovation Solution
Development of the TecomaבMnstabe’ variety, which exhibits a unique yellow orange corolla exterior (RHS 21A with highlights of 21B) and yellow interior (RHS 10A with orange yellow blush) color, achieved through selective breeding and asexual propagation, maintaining consistency across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional Tecoma breeding is used, then existing flower colors are maintained, but flower color diversity is limited
Solution Approach 1:
The patent applies parameter changes by modifying the flower color parameters of Tecoma plants through controlled hybridization. The inventor crossed different Tecoma species/varieties to produce offspring with novel color combinations (yellow-orange exterior with yellow-orange interior), thereby changing the color parameters from the traditional limited palette to expanded diversity including the distinctive two-toned effect.
Solution Approach 2:
The patent employs composite materials principle by combining genetic material from different Tecoma parents to create a composite genotype that expresses novel color characteristics. The hybrid plant combines traits from both parents to produce the unique yellow-orange exterior with yellow-orange interior coloration, which neither parent possessed alone.
2Reliability
If asexual propagation is used, then reproductive fidelity is ensured, but generation time increases
Solution Approach 1:
The patent applies preliminary action by performing asexual propagation through cuttings to establish multiple identical plants before field testing or commercial deployment. This ensures that the desired color characteristics are fixed and replicated across the population, providing reproductive fidelity and consistency before the plants are introduced to various environmental conditions.
3Adaptability or versatility
If hybridization is performed, then novel color combinations are achieved, but breeding complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct stages: parent selection, controlled cross-pollination, seedling evaluation, and propagation. This segmented approach allows the inventor to systematically manage the complexity of hybridization by handling one stage at a time, making the overall process more controllable and reproducible.

AI summary
A new and distinct hybrid of the genus Tecoma is provided. This hybrid has been named ‘Mnstabe’ for a cultivar name. The new variety is the product of a deliberate cross of interspecific origin between two hybrid plants of the genus Tecoma made in 2006. Seeds from this cross were saved and planted and the new variety was selected from a block of these hybrid seedlings. The new variety displays a uniquely different flower color previously unavailable in the genus, is compact in size, and as well is generally sterile.
