Soybean Variety 4158090 Breeding Program 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, making it challenging for breeders to consistently produce superior varieties.
Innovation Solution
The soybean variety 4158090 is developed through a specific breeding program that includes crossing and selection methods, such as backcrossing and genetic transformation, to introduce desired traits like herbicide resistance, disease resistance, and improved nutritional quality, while maintaining the elite genetic background for further breeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to combine desirable traits, 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 desired traits (herbicide resistance, disease resistance, yield potential) before crossing. The breeding program systematically evaluates parental performance and genetically characterizes them beforehand, so that when crosses are made, the offspring inherit predetermined desirable traits, reducing the time needed for multiple generations of selection and testing.
2Productivity
If multiple traits are combined in a single variety, then overall agronomic performance is improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct modules: selecting parental lines with specific traits (herbicide resistance, disease resistance, yield), making targeted crosses, evaluating F1 hybrids for desired trait combinations, and advancing only superior lines. This modular approach allows systematic combination of multiple traits while managing complexity through structured, stepwise evaluation at each stage.
3Measurement precision
If extensive testing and evaluation are conducted to identify superior individuals, then selection accuracy is improved, but resource requirements and time investment increase
Solution Approach 1:
The patent applies feedback by implementing systematic evaluation of breeding lines at multiple stages (F1 hybrid performance, F2 generation screening, multi-environment testing). Performance data from each generation feeds into selection decisions for the next generation, allowing breeders to identify superior individuals with high accuracy while optimizing resource allocation by advancing only the most promising lines through resource-intensive testing stages.
