Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars lack improved traits such as higher seed yield, disease resistance, drought tolerance, and altered fatty acid profiles, which are essential for enhancing agricultural productivity and nutritional value.
Innovation Solution
Development of a new soybean cultivar 23450022 with genetic modifications for herbicide resistance, disease tolerance, and optimized fatty acid composition, achieved through traditional breeding and genetic engineering techniques, including introgression of transgenic traits and mutagenesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional breeding methods are used to develop new soybean cultivars, then the development process is simple and resource-efficient, but it takes a long time (6-12 years) to produce a new cultivar
Solution Approach 1:
The patent applies preliminary action by creating and maintaining a diverse germplasm bank containing numerous soybean lines with different traits (disease resistance, yield potential, stress tolerance) before the actual breeding program begins. This pre-assembled genetic resource pool allows breeders to immediately start combining desirable traits without years of initial germplasm collection and evaluation, thereby reducing the overall cultivar development time while maintaining productivity.
2Reliability
If multiple desirable traits (yield, disease resistance, stress tolerance) are combined in a single cultivar, then agronomic performance is improved, but the breeding complexity and resource requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into distinct phases: (1) germplasm collection and evaluation phase, (2) parent line selection phase, (3) hybrid development phase, and (4) cultivar release phase. Each phase focuses on specific traits and has clear objectives, making the overall complex process of combining multiple desirable traits more manageable and systematic, thereby improving reliability without proportionally increasing complexity.
Solution Approach 2:
The patent uses intermediary evaluation criteria and scoring systems that act as mediators between the breeding objectives and the actual selection process. These intermediaries (such as yield potential scores, disease resistance ratings, and stress tolerance indices) allow breeders to systematically evaluate and combine multiple traits without getting overwhelmed by the complexity of directly managing all trait combinations simultaneously.
3Adaptability or versatility
If germplasm diversity is increased to access more desirable traits, then the pool of available traits is expanded, but the time and resources required for evaluation and management increase
Solution Approach 1:
The patent applies preliminary action by pre-evaluating and pre-categorizing the diverse germplasm lines according to their desirable traits (disease resistance, yield potential, stress tolerance) before the breeding program begins. This preliminary characterization allows the breeding program to immediately access and combine specific traits without needing to evaluate the entire diverse germplasm pool from scratch, thereby expanding trait availability while reducing the time and resources required for ongoing evaluation and management.
