Petunia DAMORQUEEN Cultivar Light-Responsive Flower Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Petunia varieties with interesting color patterns and attractive plant forms that can reproduce stably and consistently across different environmental conditions, as existing varieties often show variability in phenotype due to environmental factors without genotype changes.
Innovation Solution
The development of the Petunia hybrida cultivar 'DAMORQUEEN' through controlled crossing of proprietary seedlings 'c.v. 12-6708' and 'c.v. 12-6237', resulting in a mounded growth habit with red flowers and yellow stripes that increase in size and pattern complexity under higher light intensity, along with abundant flowering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If controlled crossing breeding is performed to develop new Petunia varieties with interesting color patterns and attractive plant forms, then the variety shows stable and true-to-type reproduction, but the phenotype may vary somewhat with variations in environment such as temperature, day length and light intensity
Solution Approach 1:
The patent acknowledges that environmental parameters (temperature, day length, light intensity) cause phenotype variations in Petunia 'DAMORQUEEN'. The breeding program selected for stability across these varying parameters, accepting that some phenotypic variation is inherent while maintaining genotypic consistency and true-to-type reproduction.
2Shape
If higher light intensity is applied to increase the size of yellow striping and create heart-shaped pattern, then the flower pattern becomes more complex and attractive, but the environmental conditions required become more specific and difficult to control
Solution Approach 1:
The patent describes how higher light intensity specifically affects the yellow striping configuration on the flowers, creating heart-shaped patterns along the margin. This localized response to environmental conditions allows for enhanced aesthetic quality under specific lighting conditions while the plant maintains overall adaptability.

AI summary
A new and distinct Petunia cultivar named ‘DAMORQUEEN’ is disclosed, characterized by well-branched plants with a mounded growth habit and medium vigor. Plants flower abundantly and produce large flowers. Flower color is uniquely red with yellow stripes, which can appear as heart shapes along margin with high light conditions. The new variety is a Petunia, suitable as an outdoor garden or container plant.
