Fisum White Geranium Cultivar Breeding for Branching and Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Zonal Geranium cultivars with attractive foliage and flower coloration that exhibit freely-branching and freely-flowering traits, as existing cultivars may lack these characteristics or have variations in performance due to environmental conditions.
Innovation Solution
The cultivar 'Fisum White' of Pelargonium×hortorum, developed through planned breeding, exhibits an upright and slightly spreading plant habit, dark green leaves, and semi-double white flowers, offering improved branching and flowering habits compared to parent selections, and demonstrates stability across generations through vegetative propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing Zonal Geranium cultivars are used, then basic growth is maintained, but freely-branching and freely-flowering traits are insufficient
Solution Approach 1:
The patent applies preliminary action by conducting planned cross-pollination breeding programs to pre-establish the desired freely-branching and freely-flowering genetic traits before commercial propagation. The breeding program systematically selects and combines parental lines with complementary traits, ensuring the new cultivar 'Fisum White' inherits stable branching and flowering characteristics that are then consistently reproduced through vegetative propagation.
2Ease of manufacture
If new cultivars are developed through breeding, then attractive foliage and flower coloration are achieved, but environmental adaptability may vary
Solution Approach 1:
The patent applies parameter changes by carefully controlling environmental parameters during the breeding and selection process. The new cultivar 'Fisum White' was developed and selected under specific controlled conditions (temperature, daylength, light intensity) in De Lier, The Netherlands, which optimized the expression of attractive dark green foliage and white flower coloration. These controlled parameter changes ensured stable phenotype development while maintaining adaptability.
3Stability of the object's composition
If vegetative propagation is used, then genetic stability is maintained, but phenotypic variation may occur under different environmental conditions
Solution Approach 1:
The patent applies local quality by recognizing that different environmental conditions (temperature, daylength, light intensity) affect specific phenotypic expressions locally rather than uniformly. The new cultivar 'Fisum White' maintains consistent genotype through vegetative propagation, while allowing controlled phenotypic variation in response to local environmental conditions such as temperature fluctuations and light levels, which is evident in the observed color variations under different lighting conditions.
