Petunia Dopetsmimar Compact Growth and Bi-Color Flower Mutation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Petunia X hybrida cultivars lack compact and early-flowering varieties with attractive, bi-colored flowers, and existing cultivars like 'Dueswejofa' have thinner lateral branches and less frequent flowering.
Innovation Solution
A naturally occurring mutation of Petunia X hybrida, designated as 'Dopetsmimar', exhibiting a compact, freely branching habit with light red purple and dark red purple bi-colored flowers, resulting from asexual reproduction by terminal vegetative cuttings, offering improved compactness, larger flower size, and increased flowering frequency compared to parent selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Petunia X hybrida cultivars are used, then they have adequate flowering frequency, but they lack compact growth habit and early flowering characteristics
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a mutant plant with altered growth parameters. The mutant exhibits changed physiological parameters including compact growth habit, shorter internodes, and altered flowering time, achieving both compactness and early flowering while maintaining good flowering frequency through natural mutation and asexual propagation
2Length of moving object
If existing compact Petunia cultivars are used, then they have reduced plant height, but they have thinner lateral branches and less frequent flowering
Solution Approach 1:
The mutant plant exhibits changed morphological parameters including thicker lateral branches despite compact overall size. The natural mutation resulted in altered branching patterns with increased lateral branch girth and improved structural strength, resolving the trade-off between compactness and branch robustness
3Shape
If existing Petunia cultivars with bi-colored flowers are used, then they have flower color variation, but they lack the specific light red purple and dark red purple bi-coloration with larger flower size
Solution Approach 1:
The mutant displays changed pigment parameters resulting in distinctive light red purple and dark red purple bi-colored flowers. The natural mutation altered floral coloration parameters and increased flower size, creating a novel color combination and larger blooms that enhance visual attractiveness
