Impatiens Cultivar Boddblredbi Bi-Color Double Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact and freely-branching Double Impatiens cultivars with large double flowers, excellent branching, and attractive foliage and flower coloration that can reproduce true to type through asexual propagation.
Innovation Solution
The cultivar 'Boddblredbi' of Impatiens walleriana, developed through self-pollination of a proprietary selection, exhibits a compact, mounded, and freely branching habit with dark green leaves and large red and white bi-colored double flowers, differing from parent selection in flower form and color, and is propagated via terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If self-pollination breeding is used to develop new Impatiens cultivars, then flower form and coloration can be improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by conducting multiple rounds of selection and self-pollination before final cultivar establishment. The breeder performed preliminary selection of parent plants with desired traits, followed by controlled self-pollination and multiple generations of selection to stabilize the double flower form and bi-coloration before final cultivar registration, thus preparing the genetic material in advance to achieve the desired floral characteristics.
2Productivity
If terminal cuttings are used for asexual propagation, then propagation speed increases, but ensuring true-to-type reproduction becomes more challenging
Solution Approach 1:
The patent applies feedback by implementing rigorous phenotypic evaluation of propagated plants to ensure true-to-type reproduction. The breeder continuously monitored and evaluated the propagated Impatiens plants for consistency in double flower form, bi-coloration pattern, and overall plant characteristics, using this feedback information to select and maintain only those propagation lines that faithfully reproduced the parent cultivar's traits, thus ensuring reliability while maintaining high propagation throughput.
