Soybean Cultivar S170112 Breeding for Yield and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as higher seed yield, disease resistance, drought tolerance, and improved fatty acid profile, while existing methods struggle to efficiently introduce and stabilize these traits in a single cultivar.
Innovation Solution
The introduction of soybean cultivar S170112, which includes methods for crossing, mutagenesis, and transformation to introduce transgenic or mutant traits, such as herbicide resistance and disease resistance, and the use of regenerable cells in tissue culture to produce plants with specific characteristics, allowing for the creation of superior soybean hybrids and variants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine desirable traits in soybean cultivars, then the cultivar achieves stability and uniformity, but the development process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with specific desirable traits (disease resistance, yield potential, stress tolerance) before crossing. The breeding program is designed with predetermined goals and selected parents are crossed intentionally to combine specific traits, rather than waiting for random recombination over multiple generations. This reduces the time needed to develop stable cultivars with desired characteristics.
2Adaptability or versatility
If multiple crossing and selection steps are performed to introduce desirable traits, then the cultivar achieves improved traits combination, but the process complexity and resource requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct phases: parent selection, controlled crossing, F1 generation evaluation, and selective backcrossing. Each phase has specific objectives and selection criteria. This segmented approach allows systematic introduction of multiple traits while managing process complexity through structured progression rather than simultaneous multiple operations.
3Productivity
If extensive breeding operations are conducted to achieve high yield and multiple resistance traits, then the cultivar performance is improved, but the resource consumption and operational costs increase
Solution Approach 1:
The patent applies partial action by performing a limited number of targeted backcrosses (typically 2-4 generations) rather than extensive multi-generational breeding. The selection criteria are applied at key decision points to advance only the most promising lines. This approach achieves sufficient trait integration and stability with reduced resource consumption compared to traditional extensive breeding programs.
