Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming process that requires precise planning and resource management, aiming to combine desirable traits such as higher seed yield, disease resistance, and improved agronomic quality, while existing methods struggle to efficiently introduce transgenic or mutant traits into soybean cultivars.
Innovation Solution
The introduction of the soybean cultivar S170104, which allows for methods like selfing, backcrosses, and hybrid production, along with the use of transgenic variants and regenerable cells in tissue culture to produce plants with specific traits, such as herbicide resistance and improved fatty acid profiles, through techniques like microprojectile-mediated delivery and Agrobacterium-mediated transformation.
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 in a single cultivar, but the process takes six to twelve years and requires precise forward planning with minimum changes in direction
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental germplasm with specific desirable traits (disease resistance, yield potential, fatty acid profiles) before initiating the breeding program. This advance preparation of parental lines with known characteristics allows the breeding process to proceed more efficiently with reduced need for directional changes, thereby reducing the overall breeding timeline while maintaining trait combination reliability
2Adaptability or versatility
If existing methods are used to introduce transgenic or mutant traits into soybean cultivars, then new traits can be incorporated, but the process is inefficient and time-consuming
Solution Approach 1:
The patent uses regenerable cell lines as an intermediary system to introduce and stabilize transgenic or mutant traits before integrating them into complete plants. This cell-based intermediate stage allows for efficient screening and selection of desired traits (such as herbicide resistance or modified fatty acid profiles) in a controlled environment, thereby accelerating the overall trait introduction process while maintaining adaptability
3Quantity of substance
If soybean cultivars are developed with improved seed yield and agronomic quality, then food and industrial production are maximized, but the breeding process requires extensive resource management and precise planning
Solution Approach 1:
The patent segments the breeding program into distinct phases with specific objectives: (1) selection of parental germplasm with complementary traits, (2) crossing and F1 generation evaluation, (3) backcrossing or selfing to stabilize desired traits, and (4) multi-location yield trials. This segmentation of the breeding process into manageable stages reduces program complexity while systematically achieving high grain production and agronomic quality targets
