Campanula 'Camp Inbule' Cultivar Hybridization and Propagation
Solution Overview
Problem
There is a need for a new campanula cultivar that exhibits distinct characteristics such as intense blue, star-shaped flowers, early and floriferous flowering, medium-green foliage, well-branching with thin stems, moderately vigorous growth, and a low mounding plant habit, which are not met by existing commercial varieties.
Innovation Solution
The development of the 'Camp Inbule' cultivar, resulting from the hybridization of 'CP-13-2' and 'CW-122-1' campanula plants, which has been asexually propagated and retains its characteristics through successive vegetative cuttings and tissue culture, showcasing wide-open, intense blue flowers, early flowering, and a compact mounding habit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If hybridization is performed to create new campanula varieties, then flower color intensity and shape distinctiveness are improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by performing hybridization between specific parent varieties ('CP-13-2' and 'CW-122-1') with known characteristics before formal patent filing. The breeding program was initiated in February 2001, with seed production in August 2001 and selection of promising plants by January 2002, allowing the distinctive flower characteristics to be developed in advance
2Stability of the object's composition
If asexual propagation is used to reproduce the cultivar, then genetic consistency and characteristic retention are improved, but propagation time and process complexity increase
Solution Approach 1:
The patent applies copying by using asexual propagation methods (vegetative cuttings and tissue culture) to create genetically identical copies of the selected plant. This ensures that the distinctive characteristics of 'Camp Inbule' are precisely replicated in subsequent generations without genetic variation, maintaining stability of the cultivar's composition
3Loss of time
If early flowering is achieved through selective breeding, then market timing and commercial value are improved, but breeding precision and selection difficulty increase
Solution Approach 1:
The patent applies feedback by systematically evaluating and selecting plants based on their flowering characteristics during the breeding process. The breeder observed and selected seedlings showing early flowering tendencies and distinctive flower traits, using this feedback to guide further breeding decisions and achieve consistent early flowering in the 'Camp Inbule' cultivar
