Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to significant research costs and variability in resulting soybean varieties.
Innovation Solution
The development of the soybean variety 01045692, which includes specific breeding methods like backcrossing and genetic transformation to introduce desired traits like herbicide resistance, disease resistance, and improved nutritional quality, along with tissue culture techniques for regenerable cells and plants, enabling the production of hybrid seeds and plants with consistent agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties, then genetic diversity can be maintained, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by using molecular markers to pre-identify plants carrying desired genetic traits before actual breeding occurs. This allows breeders to select parent plants with high probability of producing desired offspring, significantly reducing the time and unpredictability of conventional breeding while maintaining genetic diversity through marker-guided selection of diverse parental lines.
2Reliability
If conventional breeding techniques are used, then natural genetic variation is preserved, but research costs increase due to extended breeding cycles
Solution Approach 1:
The patent implements feedback through molecular marker analysis that provides real-time information about the presence and combination of desired traits in breeding populations. This feedback mechanism allows breeders to make informed decisions about which plants to select for further breeding, immediately adjusting the breeding program based on genetic analysis results, thereby reducing wasted resources on plants unlikely to produce desired outcomes while maintaining natural genetic variation.
3Adaptability or versatility
If multiple breeding objectives are pursued simultaneously, then variety improvement is comprehensive, but the breeding process complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into separate, manageable components based on specific traits or genetic regions. Molecular markers are used to track individual traits independently, allowing breeders to address multiple breeding objectives simultaneously by working with discrete genetic segments rather than the entire genome at once, thereby reducing overall program complexity while achieving comprehensive variety improvement.
