Cranberry Cupcake Echinacea Cultivar Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Echinacea cultivars lack a compact, vigorous variety with distinct rose pink ray florets, enlarged cranberry pink disc florets, and a multicrown, dwarf habit, which are desirable traits for horticultural applications.
Innovation Solution
A new Echinacea cultivar named 'Cranberry Cupcake' is developed through a breeding program using Echinacea purpurea 'Razzmatazz' as the seed parent, featuring rose pink ray florets, enlarged cranberry pink disc florets, a multicrown, dwarf habit, and excellent vigor, achieved through asexual propagation by division and tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Echinacea cultivars are used, then they have larger size and more spread-out growth, but they lack compact habit and dwarf form
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific growth parameters that result in a compact, dwarf habit. The 'Cranberry Cupcake' cultivar exhibits significantly reduced plant height (40 cm) compared to conventional Echinacea cultivars, while maintaining a dense, compact growth form with multiple crowns emerging from a single base, achieving the desired shape parameter transformation
2Quantity of substance
If conventional Echinacea cultivars are used, then they have fewer ray florets per inflorescence, but the new cultivar achieves fuller inflorescences with more ray florets
Solution Approach 1:
The patent applies merging by combining multiple inflorescences on single stems and increasing the number of ray florets per inflorescence. The 'Cranberry Cupcake' cultivar produces 1-4 inflorescences per stem with 15-25 ray florets each, creating fuller, more substantial flower heads that merge multiple floral elements into a single visual unit
3Shape
If conventional Echinacea cultivars are used, then they have single-crown growth habit, but the new cultivar exhibits multicrown, dwarf habit
Solution Approach 1:
The patent applies segmentation by dividing the single-crown growth habit into multiple crowns emerging from a common base. The 'Cranberry Cupcake' cultivar produces 3-10 crowns per plant, each capable of independent flowering, creating a segmented yet unified multicrown structure that increases flowering capacity while maintaining compact overall plant size
