Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soybean breeding faces challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved fatty acid profiles, which are time-consuming and resource-intensive, with only a small percentage of new varieties being selected for commercial use.
Innovation Solution
The development of the soybean variety XB31S08, which exhibits resistance to multiple diseases, herbicides, and environmental stresses, combined with advanced breeding techniques like backcrossing and genetic marker profiling to introduce new traits, ensuring uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop new soybean varieties with multiple desirable traits, then the variety can achieve comprehensive trait improvement, but the process is time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-establishing a structured breeding program with defined objectives, selecting parent lines with specific traits (e.g., disease resistance, drought tolerance, improved fatty acid profile) before the actual crossing begins. This forward planning and preparation of breeding materials reduces the overall time required to develop new varieties while maintaining comprehensive trait improvement.
2Adaptability or versatility
If extensive breeding programs are conducted to create stable, high-yielding varieties, then desirable traits can be combined, but the number of potential varieties produced is large while only a small percentage are selected for commercial use
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases and objectives: initial parent line selection, crossing experiments, evaluation stages, and commercial selection. This structured segmentation allows systematic management of the large number of potential varieties, enabling efficient evaluation and selection of the top 1-5% that meet commercial criteria while maintaining the capability to combine multiple desirable traits.
3Reliability
If multiple desirable traits are integrated into a single variety through breeding, then the variety achieves superior performance, but the breeding process requires precise forward planning and efficient resource use
Solution Approach 1:
The patent applies universality by designing a breeding program that can simultaneously evaluate and combine multiple traits (yield, disease resistance, drought tolerance, fatty acid profile) within a single integrated framework. This multi-functional approach allows the same breeding structure to pursue several objectives at once, reducing the apparent complexity while ensuring variety stability through systematic evaluation and selection.
