Floribunda Rose 'WEKaltbeba' Coral Pink Color Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rose cultivars lack a combination of elegant coral pink flowers, abundant blooms, and excellent color stability, along with a suitable growing habit for outdoor garden decoration.
Innovation Solution
The new Rosa hybrida variety 'WEKaltbeba' features coral pink, very double flowers with 37 to 69 petals, abundant blooms, excellent color stability, and an upright moderately spreading growing habit, suitable for outdoor garden decoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rose cultivars are bred for abundant blooms and elegant flower shape, then flower quantity and form are improved, but color stability deteriorates
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific petal count ranges (37-69 petals) and color characteristics (coral pink with excellent color stability). This controlled modification of quantitative and qualitative parameters resolves the contradiction by finding the optimal balance point where abundant blooms coexist with stable coloration, rather than allowing one trait to compromise the other.
2Shape
If rose cultivars are bred for very double flowers with high petalage, then flower elegance is improved, but flower size deteriorates
Solution Approach 1:
The patent resolves this contradiction by precisely controlling the petal count parameter to fall within the range of 37-69 petals. This specific parameter range allows the flower to achieve very double structure and elegance while maintaining adequate flower size (7.0-11.7 cm diameter), preventing the excessive petalage from causing flower size reduction.
3Length of stationary object
If rose cultivars are bred for medium to large flower size, then aesthetic appeal is improved, but petalage becomes lighter deteriorates
Solution Approach 1:
The patent resolves this contradiction by simultaneously controlling both flower size (7.0-11.7 cm diameter) and petalage quantity (37-69 petals). This coordinated parameter control ensures that medium to large flowers are achieved without compromising petalage density, maintaining the very double flower structure that provides aesthetic appeal.
