Coreopsis DECOREO16 Compact Habit Double Flower Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Coreopsis varieties with compact growth habits, early flowering, and fully double flowers for ornamental commercial applications, as existing varieties like 'Sundancer' and 'Walcoreop' lack these specific traits.
Innovation Solution
The development of the Coreopsis cultivar 'DECOREO16' through planned breeding, which exhibits a compact and mounded habit, early flowering, short peduncle, and fully double flowers, distinguishing it from its seed parent 'co-9-564' and comparators like 'Sundancer' and 'Walcoreop'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If Coreopsis varieties like 'Sundancer' and 'Walcoreop' are used, then they have spreading plant habit and semi double flowers, but they lack compact growth habit and fully double flowers needed for ornamental applications
Solution Approach 1:
The breeding program systematically changed key parameters including plant habit (from spreading to compact/mounded), flower type (from semi-double to fully double), and peduncle length (from long to short) through controlled crosses and selection of extreme phenotypes over multiple generations
2Length of moving object
If Coreopsis varieties with compact habit are developed, then they have shorter growth span, but they may flower later instead of earlier
Solution Approach 1:
The breeding program performed preliminary selection of seedlings exhibiting both compact habit and early flowering tendencies before advancing to propagation, ensuring these dual traits were established in the parental generation before mass multiplication
3Shape
If Coreopsis varieties produce fully double flowers, then they have enhanced ornamental value, but they require more complex breeding to achieve
Solution Approach 1:
The breeding program focused selection pressure specifically on the flower structure trait (double vs semi-double) while maintaining other desirable traits, applying localized selection pressure to achieve the complex flower type without requiring complete reworking of the entire plant phenotype

AI summary
A new and distinct Coreopsis cultivar named ‘DECOREO16’ is disclosed, characterized by early blooming of fully double flowers that are all at the same height. The new variety has very compact and mounded habit and short peduncles. The new variety is a Coreopsis, normally produced as an outdoor garden or container plant.
