Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties that combine desirable traits such as disease resistance, drought tolerance, and improved agronomic qualities, which are difficult to predict and require extensive research efforts due to the complexity of genetic combinations and environmental factors.
Innovation Solution
The development of the soybean variety S100306, which is adapted for mid-group 3 growing regions, involves a breeding history that includes specific crosses and selection methods to combine traits like disease resistance, herbicide resistance, and improved agronomic characteristics, and can be used in various breeding protocols to produce hybrid seeds and new soybean varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional soybean breeding methods are used to combine multiple desirable traits, then the complexity of genetic combinations increases, but the predictability of trait expression and breeding efficiency decrease
Solution Approach 1:
The patent segments the breeding process by first developing inbred lines with specific desirable traits (disease resistance, yield components, maturity) separately, then combining them through controlled crosses. This segmentation allows each trait to be optimized independently before integration, reducing the overall complexity of combining multiple traits simultaneously.
Solution Approach 2:
The patent applies preliminary action by developing and stabilizing inbred lines with specific traits before combining them. The inbred lines are subjected to multiple generations of selfing and selection to ensure trait stability and uniformity prior to crossing, which facilitates more predictable and efficient trait combination in subsequent hybrid generations.
2Reliability
If extensive research efforts are devoted to developing stable high-yielding varieties, then the yield and stability improve, but the time and resources required for breeding increase
Solution Approach 1:
The patent performs preliminary actions by developing inbred lines through multiple generations of selfing and selection before the combining stage. This preliminary stabilization of genetic lines ensures that when traits are combined in hybrids, the performance is more predictable and requires fewer additional generations of testing and stabilization, thereby reducing overall breeding time.
Solution Approach 2:
The patent uses copying by reproducing stable inbred lines through self-pollination across multiple generations. This copying process creates genetically uniform lines that can be reliably crossed, ensuring consistent trait expression in progeny and reducing the time needed for repeated stabilization cycles.
3Adaptability or versatility
If multiple traits are combined in a single variety, then the agronomic quality and resistance improve, but the difficulty of selecting and maintaining uniformity increases
Solution Approach 1:
The patent segments the multi-trait combination process by assigning specific traits to specific inbred lines before crossing. Each inbred line is developed to excel in particular traits (e.g., one line for disease resistance, another for yield), and these are then combined through controlled crosses. This segmentation maintains uniformity within each trait component while achieving comprehensive trait integration in the final variety.
Solution Approach 2:
The patent performs preliminary selection and stabilization of each inbred line for specific traits before combining them. This preliminary action ensures that each parental line is genetically uniform and stable for its intended traits, which facilitates uniform expression of these traits in the hybrid progeny and reduces selection difficulties in subsequent generations.
