Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as high yield, disease resistance, and adaptability to various conditions, but existing methods are slow and prone to directional changes.
Innovation Solution
The introduction of soybean variety 5PWKR60, which is a stable, high-yielding variety with improved traits such as resistance to diseases and environmental stresses, achieved through breeding and genetic modification techniques, including backcrossing and transgenic trait introgression, to create a versatile and adaptable soybean line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the variety achieves high yield and disease resistance, but the development process takes 6-12 years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits (high yield, disease resistance, stress tolerance) before initiating the breeding program. This advance preparation of germplasm with known trait profiles accelerates the breeding process by eliminating later-generation screening time while maintaining the 6-12 year development timeline for comprehensive variety testing and stabilization.
2Adaptability or versatility
If multiple crossing and selection steps are performed to achieve trait combination, then the variety achieves adaptability across different environments, but the process becomes complex and prone to directional changes
Solution Approach 1:
The patent segments the breeding process into distinct modular stages: (1) selection of parental lines with specific trait combinations, (2) controlled crossing to generate F1 hybrids, (3) systematic backcrossing with selection for desired traits, and (4) stabilization through selfing generations. This segmentation reduces overall complexity by making each stage manageable and predictable, while the cumulative effect across stages achieves comprehensive environmental adaptability.
Solution Approach 2:
The patent uses intermediate breeding generations (F1 hybrids and backcross generations) as mediators to gradually combine desirable traits from different parental lines. These intermediate stages serve as transitional forms that allow systematic introduction and stabilization of adaptability traits without overwhelming complexity in a single step, reducing the risk of directional changes by maintaining control over each generational transition.
