Calendula CDAZ0001 Cultivar Breeding for Distinct Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Calendula maritima cultivar that exhibits distinct characteristics such as orange color with a gold center, single flower form, and mound spreading plant habit, which are not adequately represented in existing varieties like 'SummerLoversSkyfire Yellow'.
Innovation Solution
The development of the Calendula maritima cultivar 'CDAZ0001' through a breeding program, which involves selfing a hybrid plant 'GUC0266-1' and selecting for specific traits like flower color, size, and plant habit, resulting in a cultivar with firmly fixed characteristics retained through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a breeding program is conducted to develop new Calendula cultivars with specific traits, then distinct characteristics such as orange color with gold center and single flower form are achieved, but the development time and breeding complexity increase
Solution Approach 1:
The breeding program utilized preliminary selection of parent plants with desired traits and conducted controlled hybridization in advance. The hybrid plant 'GUC0266-1' was developed through planned crosses before the final selection of 'CDAZ0001', allowing systematic progression toward the target phenotype rather than random breeding.
Solution Approach 2:
The breeding program incorporated continuous evaluation and selection feedback mechanisms. Multiple generations were assessed for flower color, form, and plant habit, with selected individuals propagated asexually to maintain and refine desired traits. The feedback loop between phenotypic evaluation and selective propagation accelerated the fixation of target characteristics.
2Stability of the object's composition
If selected traits are fixed through asexual reproduction, then consistent phenotype is achieved across generations, but genetic diversity is reduced
Solution Approach 1:
The breeding program segmented the trait fixation process by applying asexual reproduction (cuttings) to specific selected individuals rather than the entire population. This allowed different genotypes to be propagated independently, maintaining genetic diversity at the population level while ensuring phenotypic consistency within each cloned lineage.
Solution Approach 2:
Different propagation strategies were applied to different individuals based on their phenotypic performance. Superior individuals exhibiting the desired orange color with gold center and single flower form were selected for asexual propagation, while other individuals remained in the sexual breeding pool, creating local optimization without global homogenization.
