Duesarlish Geranium Cultivar Trait Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new and distinct cultivars of Interspecific Geranium plants with attractive flowers that exhibit uniform growth habits and stable traits across varying environmental conditions, as existing varieties may show phenotypic variations with temperature and light intensity changes without genotype variance.
Innovation Solution
The development of a new Interspecific Geranium cultivar, 'Duesarlish', resulting from a cross-pollination between Pelargonium zonale and Pelargonium peltatum, characterized by an upright to spreading habit, vigorous growth, basal branching, and large bi-colored semi-double flowers, which are stable through asexual reproduction and exhibit improved garden performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Pelargonium varieties are used, then they may have simple flower colors or growth habits, but they show phenotypic variations with temperature and light intensity changes
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific phenotypic parameters (flower color, growth habit, branching pattern) through controlled cross-pollination and vegetative propagation. The new cultivar 'Duesarlish' has been selected to maintain consistent expression of these parameters across different environmental conditions, resolving the contradiction between trait stability and environmental adaptability.
2Adaptability or versatility
If cross-pollination between Pelargonium zonale and Pelargonium peltatum is performed, then new flower colors and growth habits are produced, but phenotypic variations occur under different environmental conditions
Solution Approach 1:
The patent applies local quality by focusing on specific local characteristics of the plant (flower color, growth habit, branching pattern) and selecting individuals that exhibit desirable traits in these specific locations. The new cultivar 'Duesarlish' has been selected to maintain consistent expression of these specific local parameters, resolving the contradiction between flower color variation and phenotypic consistency.
3Reliability
If vegetative terminal cuttings are used for asexual reproduction, then stable true-to-type reproduction is achieved, but the initial establishment time is extended
Solution Approach 1:
The patent applies preliminary action by preparing and selecting the parent plant with desired traits before propagation. The new cultivar 'Duesarlish' has been carefully selected and acclimatized before being used for vegetative propagation, ensuring that the resulting plants will be true-to-type and stable, thereby justifying the extended establishment time through reliable reproduction.
