Balcoree Impatiens Cultivar Double Flower Compact Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Impatiens cultivars lack fully double-type flowers with attractive coloration and compact, freely branching growth habits, which limits their aesthetic and horticultural appeal.
Innovation Solution
The development of the Impatiens walleriana cultivar 'Balcoree' through controlled breeding, combining the characteristics of semi-double dark red flowers, dark green foliage, and a compact growth habit from parental selections, resulting in deep salmon-rose colored, double-type flowers and dark green foliage with a moderately vigorous, compact-mounded growth habit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional breeding methods are used to develop Impatiens cultivars, then flower color and type can be improved, but achieving fully double-type flowers with compact growth habit and attractive coloration simultaneously is difficult
Solution Approach 1:
The breeding program was segmented into distinct phases: selecting parental lines with specific traits (5132c-5 for dark red flowers and compact habit, 5281-5 for double flowers and bronze-green foliage), controlled cross-pollination, and systematic evaluation of progeny. This segmentation allowed each breeding objective to be addressed in a structured manner, ultimately achieving the combination of fully double flowers, compact growth, and attractive coloration.
2Shape
If selective breeding is performed to achieve specific flower characteristics, then flower type and color can be enhanced, but the time required for development and stabilization of traits increases
Solution Approach 1:
Parental lines were pre-selected and characterized for specific traits before crossing. The female parent (5132c-5) was chosen for its compact growth habit and dark red flowers, while the male parent (5281-5) was selected for its double flowers and bronze-green foliage. This preliminary selection and characterization of parental lines accelerated the breeding process by ensuring that desired traits were already present in the parents, reducing the time needed for trait stabilization in subsequent generations.
3Shape
If new cultivars are developed with enhanced flower characteristics, then aesthetic appeal is improved, but differentiation from existing cultivars becomes more challenging
Solution Approach 1:
The new cultivar 'Balcoree' was developed with a specific combination of traits that create its unique identity: fully double flowers (distinguished from semi-double varieties), deep salmon-rose coloration (distinct from parent dark red and bicolored flowers), dark green foliage, and compact-mounded growth habit. This localized combination of specific quality attributes in each trait area creates a distinctive cultivar profile that is easily differentiated from both parental lines and existing cultivars like 'Musica Pastel Salmon'.
