Canola Cultivar CE216910H Stabilizing Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new canola cultivars is a slow and costly process due to the difficulty in predicting and replicating genetically-identical inbreds or hybrids expressing specific trait characteristics, with conventional breeding methods lacking control over meiotic genetic recombination, leading to millions of possible genetic combinations and unpredictable results.
Innovation Solution
The introduction of the canola cultivar CE216910H, which allows for the production of superior hybrid seeds through crossing with other canola plants, incorporating traits such as herbicide resistance, disease resistance, and enhanced nutritional quality, using methods like selfing, backcrossing, and genetic transformation to stabilize desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional breeding methods are used to develop new canola cultivars, then the process is simple and cost-effective, but the development time is long and the results are unpredictable due to lack of control over meiotic genetic recombination
Solution Approach 1:
The patent applies preliminary action by using pre-developed inbred lines with stable, known genetic compositions as starting materials. These inbred lines are created through multiple generations of self-pollination before hybridization, ensuring that the parental genomes are fully characterized and stable, thereby enabling predictable F1 hybrid outcomes without needing to control meiotic recombination in real-time during breeding.
Solution Approach 2:
The patent uses copying by creating inbred lines that are genetically identical copies of selected parental genotypes. Through repeated self-pollination and selection, the inbred lines become homogeneous copies of the desired parental characteristics, allowing precise replication of genetic traits in the F1 generation and enabling reliable prediction of hybrid performance.
2Ease of manufacture
If conventional breeding methods are used, then the process is straightforward, but the complexity of meiotic genetic recombination creates millions of possible combinations making replication difficult
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct, manageable stages: (1) development of inbred lines through self-pollination, (2) evaluation of inbred lines for desired traits, (3) hybridization of selected inbreds to produce F1, and (4) evaluation and release of superior hybrids. This segmentation isolates the complex genetic recombination to specific stages while keeping the overall process simple and controllable.
Solution Approach 2:
The patent uses parameter changes by transitioning from outcrossing (natural pollination) to controlled self-pollination during the inbred line development phase. This change in the pollination parameter enables complete control over genetic combinations, reducing the millions of possible outcomes to a single predictable F1 generation from standardized inbred parents.
3Reliability
If conventional breeding methods are used, then the approach is traditional and well-established, but the inability to control meiotic recombination leads to unpredictable and non-replicable results
Solution Approach 1:
The patent applies preliminary action by completing the inbred line development and genetic stabilization before hybridization. The inbred lines are created through multiple generations of self-pollination and selection, ensuring that all genetic recombination has been controlled and stabilized in advance. This preliminary completion of the inbreeding process eliminates uncertainty about the parental genomes, ensuring reliable and reproducible F1 hybrid results.
