Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new canola cultivars is a time-consuming and unpredictable process due to the complexity of inheritance and the need for precise genetic combinations, making it challenging to produce cultivars with desired traits such as high yield, disease resistance, and nutritional quality consistently.
Innovation Solution
The introduction of the canola cultivar G31064, which is developed through traditional breeding and dihaploid methodology, incorporating genes for herbicide resistance, disease tolerance, and improved nutritional profile, allowing for the creation of stable and uniform high-yielding canola plants with enhanced agronomic traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop new canola cultivars, then desired traits such as high yield, disease resistance, and nutritional quality can be achieved, but the process is time-consuming and unpredictable due to complex inheritance patterns
Solution Approach 1:
The patent applies parameter changes by utilizing dihaploid methodology to alter the chromosomal composition of canola plants. By creating dihaploid plants with half the normal chromosome number and then doubling them, the breeding process achieves fixed, stable genetic combinations more rapidly than traditional diploid breeding, thereby reducing the time required to obtain consistent trait expression while maintaining reliability.
Solution Approach 2:
The patent employs copying through the use of molecular markers and genomic selection techniques. By copying and analyzing specific genetic markers associated with desired traits, the breeding process can identify and select plants with target characteristics without waiting for phenotypic expression, significantly accelerating the breeding cycle while maintaining trait consistency.
2Productivity
If complex genetic combinations are pursued to achieve desired traits, then improved agronomic performance can be obtained, but the unpredictability of inheritance makes consistent trait expression difficult
Solution Approach 1:
The patent implements feedback mechanisms through molecular marker-assisted selection and genomic evaluation. By continuously monitoring and selecting plants based on their genetic markers and performance data, the breeding program can adjust selections to ensure consistent expression of desired traits while maintaining high productivity, thereby resolving the unpredictability of inheritance.
Solution Approach 2:
The patent applies preliminary action by performing genetic analysis and marker screening before the actual breeding and phenotypic evaluation stages. By pre-identifying plants with desired genetic combinations through molecular markers, the process eliminates much of the unpredictability associated with traditional breeding, ensuring consistent trait expression while maintaining high yield potential.
3Adaptability or versatility
If multiple traits are combined in a single cultivar, then agronomic quality improves, but the complexity of achieving and maintaining these combinations increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into distinct modules: molecular marker development, germplasm collection, dihaploid generation, genomic selection, and field evaluation. This segmentation allows each trait combination to be developed and optimized independently, reducing the overall complexity of managing multiple traits while maintaining high agronomic quality.
Solution Approach 2:
The patent uses molecular markers and genomic selection as intermediaries between the desired traits and the actual plant breeding process. These intermediaries simplify the complexity by providing objective, measurable criteria for selection, allowing multiple traits to be combined systematically without requiring complex manual selection processes.
