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 tolerance to environmental stresses, 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 soybean variety 5PSWB23, which is stable and high-yielding, with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce plants and plant parts with improved agronomic characteristics, including resistance to diseases and environmental stresses.
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 six to twelve years and is directionally unstable
Solution Approach 1:
The patent applies parameter changes by utilizing molecular markers to detect and select specific genetic traits at the DNA level, transforming the breeding process from phenotypic selection to genotypic selection. This allows breeders to track and combine desired traits (such as disease resistance genes and yield-related markers) with precise control over genetic composition, thereby achieving directional stability while significantly reducing the time required for variety development
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then agronomic performance is improved, but the breeding process becomes more complex and resource-intensive
Solution Approach 1:
The patent applies segmentation by breaking down the complex breeding process into manageable components through molecular marker-assisted selection. Each desired trait (disease resistance, yield, maturity) is tracked using specific molecular markers, allowing breeders to independently select and combine these traits systematically. This segmented approach to trait selection simplifies the overall breeding process while enabling the combination of multiple desirable traits in a single variety
3Measurement precision
If traditional selection methods are used, then resource efficiency is low, but the process lacks precision in selecting desired traits
Solution Approach 1:
The patent applies mechanics substitution by replacing traditional mechanical/phenotypic selection methods with molecular marker-based genotypic selection. Instead of visually assessing plant traits after they manifest phenotypically (which is imprecise and time-consuming), the invention uses DNA markers to directly detect and select for desired genetic traits at the molecular level. This substitution dramatically improves measurement precision for trait selection while simultaneously increasing breeding productivity through faster, more accurate selection cycles
