Arenaria Lemon Ice Cultivar Mutation Compact Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Arenaria montana that exhibits specific floral and habit characteristics, as existing cultivars like 'Avalanche' and 'Sapare' differ in flower color and compactness, and typical Arenaria montana species have smaller white flowers and less compact habits.
Innovation Solution
The 'Lemon Ice' cultivar, discovered as a branch mutation of 'Avalanche', features lemon yellow flowers, a dense and compact spreading habit, and is propagated through tip cuttings, maintaining its characteristics in successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If typical Arenaria montana species are used, then the plant has smaller white flowers and less compact habit, but the flower color and compactness are not desirable
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a specific branch mutation that has naturally altered floral and habit parameters. The mutation changes flower color from white to lemon yellow and increases plant compactness, creating a distinct cultivar with modified phenotypic parameters while maintaining biological stability through asexual reproduction
2Shape
If 'Avalanche' cultivar is used, then the plant has compact habit, but the flower color is white instead of lemon yellow
Solution Approach 1:
The patent applies local quality by identifying a specific localized mutation within the 'Avalanche' cultivar that produces lemon yellow flowers while maintaining the compact habit. This local variation in flower color (lemon yellow vs. white) within the same cultivar lineage allows differentiation without sacrificing the desirable compact growth form
3Shape
If 'Sapare' cultivar is used, then the plant has compact form, but the flower color is white instead of lemon yellow
Solution Approach 1:
The patent applies local quality by identifying a specific localized mutation within the 'Sapare' cultivar that produces lemon yellow flowers while maintaining the compact form. This local variation in flower color (lemon yellow vs. white) within the same cultivar lineage allows differentiation without sacrificing the desirable compact growth form
