Coreopsis Red Hot Vanilla Narrow Foliage Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct threadleaf coreopsis cultivar that exhibits unique traits such as narrow foliage, compact height, dense mounded habit, heavy flowering, and specific inflorescence characteristics, which are not met by existing cultivars like 'Starlight', 'Balupteam', and 'Balupteamed'.
Innovation Solution
The development of Coreopsis 'Red Hot Vanilla' from seed collected in 2014, which is stable through asexual propagation and reproduces true to type, featuring narrow foliage, compact height, dense mounded habit, heavy flowering with creamy ray ligules and dark red central eyes, and a long flowering period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing coreopsis cultivars like 'Starlight', 'Balupteam', and 'Balupteamed' are used, then they provide flowering characteristics, but they lack the unique combination of narrow foliage, compact height, dense mounded habit, and specific inflorescence characteristics
Solution Approach 1:
The patent segments the desired plant characteristics into distinct components: narrow foliage, compact height, dense mounded habit, and specific inflorescence features. By selecting and combining these segmented traits through controlled breeding, the patent creates a unique phenotype that distinguishes Coreopsis 'Red Hot Vanilla' from existing cultivars.
Solution Approach 2:
The patent applies local quality by specifying particular characteristics for different parts of the plant: the foliage has a narrow, thread-like quality; the overall habit is compact and mounded; and the inflorescences have specific features including creamy ray ligules with dark red central eyes. This localized optimization of traits creates the distinctive phenotype.
2Reliability
If a new cultivar is developed with specific unique traits, then distinctiveness is improved, but stability through asexual propagation must be ensured
Solution Approach 1:
The patent employs asexual propagation through cuttings to allow the plant to reproduce true to type without genetic variation. This self-service propagation method ensures that the unique phenotype characteristics are consistently maintained across generations, providing both distinctiveness and stability.
3Adaptability or versatility
If the plant is adapted to various environmental conditions and temperature extremes, then hardiness is improved, but the phenotype may vary slightly with environmental changes
Solution Approach 1:
The patent acknowledges environmental variability as a potential source of phenotype variation and addresses it through careful selection and stabilization of the genotype. By establishing a stable genetic foundation through controlled breeding and asexual propagation, the patent cushions against environmental influences, ensuring that only minimal phenotype variation occurs despite environmental changes.
