Pelargonium Dueimvor Hybrid Breeding for Trait Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new and distinct interspecific hybrid Geranium plants with uniform dark green-colored leaves and attractive flowers, as existing varieties may not consistently exhibit desired traits under varying environmental conditions.
Innovation Solution
The development of a new interspecific hybrid Geranium plant, 'Dueimvor', resulting from a cross-pollination between Pelargonium peltatum and Pelargonium hortorum, characterized by a compact, upright growth habit, vigorous branching, and bright red-colored single-type flowers, which are stable and reproduce true to type through vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Geranium varieties are used, then they may exhibit certain flower colors and growth habits, but they do not consistently display uniform dark green leaves and attractive flowers under varying environmental conditions
Solution Approach 1:
The patent applies parameter changes by creating a new hybrid cultivar 'Dueimvor' with specifically selected genetic parameters that maintain uniform dark green leaf color and attractive flower characteristics across varying environmental conditions. The hybridization between Pelargonium peltatum and Pelargonium hortorum produces offspring with stabilized phenotypic parameters that are more consistent than parent varieties.
Solution Approach 2:
The patent employs composite materials principle through hybridization, combining genetic material from two different Pelargonium species (P. peltatum and P. hortorum) to create a new composite genotype. This composite genetic structure integrates desirable traits from both parents, resulting in a cultivar with improved consistency and reliability of morphological features under varying environmental conditions.
2Manufacturing precision
If a cross-pollination between Pelargonium peltatum and Pelargonium hortorum is performed, then new uniform intersspecific hybrid Geranium plants with dark green-colored leaves and attractive flowers are created, but the breeding process requires controlled greenhouse environment and multiple generations of selection
Solution Approach 1:
The patent applies preliminary action by conducting the cross-pollination and initial selection processes in a controlled greenhouse environment before commercial propagation. The inventor performed the cross between selected P. peltatum and P. hortorum parents, then selected and asexually reproduced the superior 'Dueimvor' hybrid in controlled conditions to establish uniformity before wider dissemination, thereby preparing the cultivar in advance for reliable production.
Solution Approach 2:
The patent employs copying principle through asexual reproduction by vegetative cuttings. Once the superior 'Dueimvor' hybrid plant was identified and selected in May 2008, it was propagated asexually to create multiple identical copies that all exhibit the same uniform dark green leaves and attractive flowers, thereby multiplying the precise phenotype without genetic variation and reducing the time needed to produce uniform plants.
3Stability of the object's composition
If the new intersspecific hybrid Geranium plant 'Dueimvor' is propagated by vegetative cuttings, then the unique features are stable and reproduced true to type, but the propagation process requires controlled greenhouse environment
Solution Approach 1:
The patent applies self-service principle through asexual propagation by vegetative cuttings. The 'Dueimvor' hybrid plant propagates itself asexually, producing clones that inherently maintain the same genetic composition and unique features. This self-propagation mechanism ensures stability of characteristics without requiring complex external intervention, though controlled greenhouse conditions provide optimal environment for the propagation process.
