Soybean Variety D4361423 Breeding for Trait Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean varieties is a time-consuming and unpredictable process due to the complexity of combining desirable traits like seed yield, disease resistance, and environmental adaptability, with conventional breeding methods lacking control over genetic combinations and requiring extensive resources.
Innovation Solution
The soybean variety D4361423 is developed through a specific breeding history and can be used for crossing with itself or other plants to produce hybrid seeds and plants, incorporating traits such as herbicide resistance, disease resistance, and improved nutritional quality, utilizing methods like backcrossing and genetic transformation to introduce desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop new soybean varieties, then genetic diversity and adaptability are improved, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desirable traits (herbicide resistance, disease resistance, yield potential) before crossing. The breeding program systematically evaluates parent lines for specific traits and prepares crossing materials in advance, reducing the overall breeding timeline while maintaining genetic diversity and adaptability in the final variety.
2Adaptability or versatility
If conventional breeding methods are used to combine desirable traits, then trait combination is achieved, but resource expenditure increases
Solution Approach 1:
The patent implements feedback by systematically evaluating breeding lines at multiple stages for specific traits (herbicide resistance, disease resistance, yield). Performance data from field trials and laboratory tests feed back into selection decisions, allowing the breeding program to efficiently identify and advance only those lines that meet predetermined criteria, thereby reducing resource expenditure while achieving desired trait combinations.
3Reliability
If extensive crossing and selection is performed to improve traits, then genetic superiority is achieved, but unpredictability of results increases
Solution Approach 1:
The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-assisted selection. DNA markers linked to desirable traits (herbicide resistance, disease resistance) are used to predict offspring performance before phenotypic expression occurs. This substitution of molecular analysis for traditional field evaluation reduces unpredictability and accelerates the breeding process while maintaining genetic superiority.
