Petunia DPETCPGEM Cultivar with Stable Violet-Blue Striped Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Petunia varieties lack unique and stable flower color patterns that are influenced by environmental conditions, and they often have less vigorous growth habits and fewer flowers compared to desired traits.
Innovation Solution
The development of the Petunia hybrid cultivar 'DPETCPGEM' with a semi-trailing growth habit, medium branching, violet-blue flowers with 5 white stripes and a white rim, and abundant flowering, which remains true to type across multiple generations through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If Petunia varieties are bred for unique flower color patterns, then flower color pattern uniqueness is improved, but stability across environmental conditions deteriorates
Solution Approach 1:
The patent applies parameter changes by breeding a cultivar where flower color pattern parameters (violet-blue base with white stripes and rim) are stabilized through genetic selection. The phenotype maintains consistent color parameters across varying environmental conditions, resolving the contradiction between uniqueness and stability.
2Area of moving object
If Petunia varieties are bred for larger flower size, then flower size is improved, but flowering abundance deteriorates
Solution Approach 1:
The patent merges two previously separate traits into one cultivar: large flower size and abundant flowering. The cultivar 'DPETCPGEM' simultaneously exhibits both large flowers and high flowering abundance, eliminating the trade-off between these two parameters through genetic combination.
3Strength
If Petunia varieties are bred for vigorous growth habit, then growth vigor is improved, but branching complexity deteriorates
Solution Approach 1:
The patent applies local quality by differentiating growth characteristics in specific zones: the cultivar exhibits vigorous vertical growth (main stems) with controlled lateral branching. This creates a semi-trailing habit where vigor is expressed in height while branching remains moderate, resolving the contradiction between vigor and complexity.
