Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean varieties lack improved combinations of traits such as higher seed yield, disease resistance, herbicide tolerance, and nutritional quality, making them less efficient and less adaptable to various growing conditions.
Innovation Solution
Development of the soybean variety 01098221, which incorporates genetic modifications and traits such as herbicide resistance, disease resistance, and improved nutritional quality through methods like genome editing using engineered nucleases, and breeding techniques like backcrossing and hybridization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to develop new varieties with improved traits, then trait improvement may be achieved, but the process is time-consuming and unpredictable
Solution Approach 1:
The patent applies parameter changes by transitioning from conventional breeding methods to genetic transformation techniques. This involves changing the fundamental approach from phenotypic selection and crossing to direct genetic modification, thereby altering the parameters of breeding predictability and time efficiency. The genetic transformation method allows for precise introduction of desired traits without the lengthy and unpredictable process of traditional breeding.
2Productivity
If traditional breeding methods are used, then resource allocation can be managed with existing techniques, but extensive research and resource allocation are required over long periods
Solution Approach 1:
The patent employs preliminary action by pre-selecting and characterizing parental lines with specific desirable traits before breeding. This includes identifying parents with resistance to diseases such as sudden death syndrome, cyst nematode, and brown stem rot, as well as parents with desirable agronomic characteristics. By preparing and characterizing parental germplasm in advance, the breeding process becomes more efficient and requires fewer resources over time.
Solution Approach 2:
The patent uses molecular markers as intermediaries to track and select for desired traits during breeding. Molecular marker-assisted selection serves as a mediator between phenotypic observation and genotypic selection, enabling more efficient tracking of inheritance patterns and desired traits. This intermediary technique reduces the time and resources required for phenotypic evaluation and selection across multiple generations.
3Adaptability or versatility
If conventional breeding is used to combine multiple traits, then trait combination is possible, but the process becomes increasingly complex and unpredictable
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases and components. This includes separate steps for selecting parental lines with specific traits, performing controlled crosses, evaluating progeny for individual traits, and combining lines with complementary characteristics. By segmenting the breeding process into manageable stages, the complexity of combining multiple traits is reduced and made more systematic.
Solution Approach 2:
The patent employs local quality by selecting parental lines that excel in specific local conditions or for specific traits. For example, one parent may be selected for resistance to sudden death syndrome while another is selected for high yield potential. Each parent contributes specific local qualities or specialized traits, which are then combined in the progeny. This approach simplifies the breeding program by focusing on combining specialized lines rather than attempting to improve all traits simultaneously in a single line.
