Soybean Cultivar 21031508 With Marker-Guided Trait Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars lack improved combinations of desirable traits such as higher seed yield, disease resistance, drought tolerance, and altered fatty acid profiles, which are time-consuming to develop and require precise planning and resource efficiency.
Innovation Solution
Development of a new soybean cultivar 21031508 with genetic modifications for herbicide resistance, disease tolerance, and improved fatty acid composition, achieved through crossing, mutagenesis, and transformation methods, including the use of specific genetic markers and promoters for trait introduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop new soybean cultivars, then desirable traits can be combined, but the process takes 6-12 years and requires significant resources
Solution Approach 1:
The patent applies preliminary action by pre-characterizing parental germplasm for specific desirable traits (disease resistance, yield components, fatty acid profiles) before crossing. This advance preparation and selection of parents with known trait profiles accelerates the breeding process while ensuring reliable trait combination in the offspring, reducing the typical 6-12 year development timeline.
2Adaptability or versatility
If multiple desirable traits are combined in a single cultivar, then agronomic performance improves, but the breeding process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: selecting parents with specific single traits (disease resistance, yield traits, fatty acid composition), crossing them systematically, and evaluating offspring for cumulative trait expression. This segmented approach to multi-trait breeding reduces program complexity while achieving versatile cultivars with multiple desirable characteristics.
3Manufacturing precision
If parental germplasm is selected with specific traits, then offspring inherit desirable characteristics, but selection and evaluation require precise measurement and analysis
Solution Approach 1:
The patent applies mechanics substitution by replacing traditional phenotypic selection with molecular marker-based genotypic selection. DNA markers and genetic analysis methods are used to precisely track inheritance of desirable traits from parental germplasm to offspring, eliminating the need for time-consuming and imprecise field evaluation while achieving accurate trait inheritance prediction.
