Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, and often result in varieties that are not easily replicable.
Innovation Solution
The development of the soybean variety 5PQNG18, which incorporates specific genetic loci for traits like herbicide resistance, disease resistance, and improved nutritional quality through genetic transformation and backcrossing, allowing for the creation of stable and high-yielding soybean plants with predictable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties, then genetic diversity can be maintained, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (herbicide resistance, disease resistance, yield characteristics) before crossing. The breeding program systematically evaluates parental germplasm and pre-determines crossing strategies based on target trait combinations, reducing the time required for random screening and selection in conventional breeding.
Solution Approach 2:
The patent implements feedback mechanisms through systematic evaluation of breeding progeny for desired traits. Performance data from field trials and laboratory assessments feed back into the breeding program to guide subsequent crossing decisions and selection criteria, improving predictability and reducing the number of generations needed to develop stable varieties.
2Reliability
If conventional breeding techniques are used, then natural genetic variation is preserved, but the resulting varieties lack stability and replicability
Solution Approach 1:
The patent segments the breeding process into distinct phases: parental selection, controlled crossing, progeny evaluation, and variety stabilization. Each phase has specific objectives and selection criteria, allowing systematic improvement of variety stability while maintaining breeding efficiency. The segmentation enables focused selection for desired traits without relying on random genetic variation.
Solution Approach 2:
The patent changes key breeding parameters by using molecular markers to track inheritance of specific traits and by controlling crossing designs to achieve desired genetic compositions. This allows precise control over variety stability and replicability while maintaining efficient breeding timelines through marker-assisted selection and controlled pollination protocols.
3Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the overall performance improves, but the breeding complexity increases
Solution Approach 1:
The patent applies universality by developing parental lines that serve multiple functions: they provide herbicide resistance, disease resistance, and yield improvement simultaneously. The breeding program uses multi-trait selection criteria and evaluates progeny for multiple desirable characteristics in parallel, reducing the need for sequential breeding steps and simplifying the overall program complexity.
Solution Approach 2:
The patent uses molecular markers as intermediaries to track and select for multiple desirable traits simultaneously. These markers serve as mediators that allow breeders to monitor inheritance of complex trait combinations without extensive phenotypic evaluation, reducing breeding program complexity while maintaining high adaptability through multi-trait selection.
