Angelonia DALON9 Cultivar Breeding for Compact Habit and Large Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Angelonia varieties with improved ornamental characteristics for commercial applications, specifically compact growth habit and larger flower size, which are not adequately met by existing varieties.
Innovation Solution
The development of the Angelonia angustifolia 'DALON9' cultivar, resulting from a breeding program, which exhibits a compact growth habit and produces larger, dark blue flowers compared to its parents, while maintaining stability through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Angelonia varieties are used, then flower color variety is available, but flower size is small and growth habit is not compact
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in larger flower size (3.0 cm diameter) and compact growth habit (30 cm height with 30 cm spread). The breeding program systematically changed the parameters of flower size, plant height, and spread to achieve the desired combination of traits that differ from conventional varieties.
2Shape
If larger flowers are bred, then ornamental value increases, but plant size may increase reducing compactness
Solution Approach 1:
The patent applies local quality by concentrating the breeding focus on specific local characteristics - specifically enlarging the flower size while maintaining control over overall plant dimensions. The cultivar achieves 3.0 cm flower diameter (larger than conventional varieties) while simultaneously maintaining a compact 30 cm height and spread, creating localized improvement in flower size without compromising overall plant compactness.
