Dianthus Red Rouge Cultivar Breeding for Flower Shape and Compact Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Dianthus cultivars lack a combination of distinct traits such as large, fully rounded flowers with burgundy red and rosy-pink flecked petals, prolonged flowering periods, compact habit, and dense blue-green foliage, which are not adequately represented in known varieties like 'Paint the Town Magenta', 'Paint the Town Fuchsia', KAHORI®'Scarlet', 'Paint the Town Red', 'Devon Xera', and 'Wp11 TYR04'.
Innovation Solution
Dianthus 'Red Rouge' is a new cultivar resulting from a cross between proprietary hybrids 12-85-1 and 12-47-4, characterized by single large flowers with five overlapping petals, burgundy red petals with rosy-pink flecking, numerous flowers on upright stems, prolonged flowering, and compact, glaucous blue-green foliage, achieved through asexual propagation and sterile shoot-tip tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Dianthus cultivars are used, then breeding simplicity is maintained, but the combination of large fully rounded flowers, prolonged flowering periods, and compact habit is not achieved
Solution Approach 1:
The patent combines multiple desirable traits from different parent plants into a single new cultivar 'Red Rouge'. The cross between parent plants with different characteristics (one with pinkish flowers and dark red eye, another with dark red flowers) produced offspring that merged these traits to create large fully rounded flowers with burgundy red petals and rosy-pink flecking, along with prolonged flowering and compact habit that neither parent possessed alone
2Adaptability or versatility
If existing Dianthus cultivars are selected, then immediate availability is achieved, but the specific combination of burgundy red petals with rosy-pink flecking, compact habit, and dense blue-green foliage is not obtained
Solution Approach 1:
The patent achieves local quality by creating distinct regional characteristics within the plant's morphology. The new cultivar exhibits burgundy red petals with specific rosy-pink flecking patterns concentrated in certain areas, dense blue-green foliage with particular texture, and compact habit with upright branching. These localized trait expressions differentiate 'Red Rouge' from parent plants and existing cultivars, providing consistent identification and adaptability across varying environmental conditions

Each flower has five overlapping petals that are burgundy red with irregularly rosy-pink flecking and edges. The flowering season is strong for four weeks beginning in late spring and continues less densely to early fall. The habit is compact and dense with glaucous blue-green foliage.
