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 environmental tolerance, while existing methods are inefficient and directionally unstable, taking six to twelve years from the first cross to delivering finished seed to farmers.
Innovation Solution
The introduction of the novel soybean variety 5PAWC77, which includes methods for crossing, introgressing transgenic, mutant, or native traits, and characterizing soybean plants to produce stable, high-yielding varieties with improved agronomic characteristics, disease resistance, and environmental tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the resulting varieties achieve high yield and stability across environments, but the development process takes six to twelve years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by pre-establishing a diverse panel of soybean lines with known trait profiles before beginning the breeding process. This allows breeders to select parents with complementary traits more efficiently, reducing the time required to develop stable, high-yielding varieties while maintaining reliability through systematic trait combination
2Adaptability or versatility
If traditional breeding methods are used to combine multiple desirable traits, then varieties with improved agronomic characteristics are achieved, but resource efficiency is reduced due to the lengthy development process
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding process into distinct phases: (1) establishing a pre-characterized panel of lines, (2) selecting parental combinations based on desired trait profiles, (3) conducting targeted crosses, and (4) evaluating progeny. This segmented approach improves resource efficiency by focusing efforts on specific trait combinations rather than exhaustive breeding, while maintaining adaptability through the diverse panel
3Stability of the object's composition
If conventional breeding approaches are used to develop new varieties, then directional stability is improved through careful selection, but the process becomes inefficient and time-consuming
Solution Approach 1:
The patent applies feedback by systematically evaluating and characterizing traits in the pre-established panel of soybean lines before selection. This feedback mechanism allows breeders to make informed decisions about parental combinations, ensuring directional stability toward desired traits while improving efficiency by avoiding unsuccessful crossing attempts. The feedback loop continues through progeny evaluation to confirm trait inheritance
