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 development of the canola cultivar DN040244A, which is a high oleic, low linolenic acid cultivar resistant to Blackleg and Fusarium wilt, with integrated herbicide tolerance and improved nutritional profile, achieved through traditional breeding and dihaploid methodology, along with genetic engineering techniques to introduce desired traits like imidazolinone resistance and enhanced oil quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop new canola cultivars, then genetic diversity and trait combinations can be achieved, but the process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by creating and maintaining a pre-characterized germplasm collection with known genetic traits and marker profiles. This allows breeders to select parental lines with desired characteristics before crossing, significantly reducing the time required to develop new cultivars with specific trait combinations while maintaining genetic diversity.
Solution Approach 2:
The patent implements feedback through molecular marker-assisted selection during the breeding process. By monitoring genetic markers in intermediate generations, breeders can track the inheritance of desired traits and make informed selection decisions, accelerating the breeding cycle and improving predictability of outcome traits.
2Productivity
If multiple desirable traits are combined in a single cultivar, then agricultural productivity and market value improve, but the complexity of achieving precise genetic combinations increases
Solution Approach 1:
The patent applies segmentation by breaking down the complex task of combining multiple traits into manageable segments using molecular markers. Each desired trait is associated with specific marker profiles that can be tracked independently through generations, allowing systematic combination of multiple traits without overwhelming complexity.
Solution Approach 2:
The patent uses parameter changes by shifting from phenotypic selection to genotypic selection based on molecular marker profiles. This changes the selection parameter from observable traits to genetic markers, enabling more precise and efficient combination of multiple desirable traits in single cultivars.
3Measurement precision
If molecular marker profiles are used to characterize germplasm, then selection precision improves, but the initial characterization process becomes more complex
Solution Approach 1:
The patent applies preliminary action by performing comprehensive molecular marker characterization on germplasm collections before breeding operations. This initial investment in characterization creates a reusable database that simplifies subsequent selection processes, improving measurement precision without repeating the complex characterization work.
