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, leading to genetic variability and difficulty in replicating superior varieties.
Innovation Solution
The development of the soybean variety A1035398, which combines desirable traits through a specific breeding history and genetic transformation, including a single locus conversion, to produce plants with improved agronomic characteristics, disease resistance, and herbicide tolerance, using techniques like backcrossing and genetic transformation to introduce desired traits while maintaining the variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties with desirable traits, then genetic variability and unpredictability occur, but the breeding process is time-consuming and difficult to replicate
Solution Approach 1:
The patent applies parameter changes by transitioning from conventional phenotypic selection to marker-assisted selection using DNA markers. This changes the breeding parameter from visual trait assessment to molecular genetic analysis, enabling more precise and reliable selection of desirable traits while reducing breeding time and increasing reproducibility.
Solution Approach 2:
The patent replaces the mechanical/conventional breeding system with a molecular biology-based system. Instead of relying on traditional cross-pollination and phenotypic observation, the invention uses DNA markers and molecular techniques to track and select for desirable traits, thereby reducing breeding time and improving consistency.
2Manufacturing precision
If conventional breeding techniques are used to combine desirable traits, then genetic variability is generated, but the process lacks precision and predictability
Solution Approach 1:
The patent replaces conventional phenotypic-based breeding with molecular marker-assisted selection. This substitution enables precise tracking of specific genes and traits at the DNA level, allowing breeders to combine desirable traits with high precision and predictability while maintaining variety stability across generations.
Solution Approach 2:
The patent introduces DNA markers as intermediaries between the breeding process and the desired traits. These molecular markers serve as mediators that allow indirect selection for desirable traits based on their genetic markers, thereby achieving precise trait combination without direct phenotypic observation.
3Adaptability or versatility
If conventional breeding techniques are used to develop new varieties, then genetic diversity is achieved, but the process is complex and difficult to manage
Solution Approach 1:
The patent replaces complex conventional breeding management with molecular marker-based systems. This substitution simplifies the breeding program by providing objective, quantifiable genetic information that can be systematically tracked and managed, thereby reducing the complexity of managing genetic diversity while maintaining adaptability.
Solution Approach 2:
The patent implements feedback mechanisms through molecular marker analysis that provides real-time information about the genetic composition of breeding populations. This feedback allows for continuous monitoring and adjustment of the breeding program, simplifying the management of genetic diversity and improving adaptability.
