Fiwobic Zonal Geranium Cultivar Breeding for Uniform Star-Shaped Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Zonal Geranium cultivars with uniform star-shaped flowers and attractive foliage that can reproduce true to type and exhibit vigorous growth and good garden performance, as existing cultivars may vary significantly with environmental conditions and cultural practices.
Innovation Solution
The development of the 'Fiwobic' cultivar of Pelargonium×hortorum, resulting from a planned breeding program, which features an upright and rounded plant habit, freely branching and flowering, with star-shaped dark green leaves and bi-colored red-purple and white flowers, achieved through vegetative terminal cuttings and stable reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Zonal Geranium cultivars are used, then they may have attractive foliage and flower coloration, but they vary significantly with environmental conditions and cultural practices
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific phenotypic parameters (plant habit, leaf shape, flower coloration) through controlled breeding. The cultivar 'Fiwobic' was developed by changing the genetic parameters of Pelargonium×hortorum through cross-pollination of proprietary selections, resulting in a cultivar with fixed characteristics that do not vary significantly with environmental conditions.
2Manufacturing precision
If new cultivars are bred to have uniform star-shaped flowers and attractive foliage, then plant vigor and flower color are improved, but breeding complexity and time are increased
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination experiments before final cultivar development. The inventor performed preliminary cross-pollination of proprietary selections in 2004, then systematically evaluated the progeny in a controlled environment starting in 2005, eventually selecting the desired plant in June 2005 and propagating it through vegetative terminal cuttings since January 2006.
Solution Approach 2:
The patent applies copying by using vegetative terminal cuttings to reproduce the selected cultivar 'Fiwobic' true-to-type. Since January 2006, asexual reproduction through vegetative terminal cuttings has been used to produce multiple copies of the selected plant, ensuring stable inheritance of the unique features without the complexity of seed-based breeding.
3Productivity
If plants are bred for vigorous growth and good garden performance, then productivity is improved, but control over plant characteristics becomes more difficult
Solution Approach 1:
The patent applies local quality by focusing the breeding program on specific local characteristics of the plant - namely upright and rounded plant habit, freely branching habit, star-shaped leaves, and bi-colored flowers. By concentrating selection pressure on these specific local qualities rather than overall plant performance, the inventor achieved both vigor and characteristic consistency in the 'Fiwobic' cultivar.
