Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as higher seed yield, disease resistance, drought tolerance, and improved fatty acid profile, while existing methods are limited in efficiently introducing transgenic or mutant traits into soybean cultivars.
Innovation Solution
The introduction of soybean cultivar S170029, which allows for methods such as selfing, backcrossing, and transformation to introduce transgenic or mutant traits, including herbicide resistance and disease resistance, through techniques like microprojectile-mediated delivery and Agrobacterium-mediated transformation, enabling the creation of regenerable cells for tissue culture and production of superior soybean hybrids.
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 using molecular markers to identify and select plants with desired traits before traditional breeding proceeds. This allows breeders to pre-screen large populations for specific genetic markers associated with desirable traits (disease resistance, yield, fatty acid profile), significantly reducing the time required to develop new cultivars while maintaining trait combination stability.
Solution Approach 2:
The patent replaces mechanical/phenotypic selection methods with molecular marker-based selection. Instead of visually inspecting and manually selecting plants based on physical traits, the invention uses DNA marker technology to detect and select for desired genetic traits at the molecular level, accelerating the breeding process from 6-12 years to a fraction of that time.
2Adaptability or versatility
If transgenic or mutant traits are introduced into soybean cultivars, then improved traits such as herbicide resistance and disease resistance can be achieved, but existing methods are limited in efficiently introducing these traits
Solution Approach 1:
The patent replaces traditional mechanical crossbreeding methods with molecular marker-assisted selection and transformation techniques. This substitution enables efficient introduction of transgenic and mutant traits by allowing precise tracking and selection of desired genetic modifications, significantly improving both the ease and efficiency of introducing diverse traits into soybean cultivars.
Solution Approach 2:
The patent uses molecular markers as intermediaries to facilitate the introduction of transgenic and mutant traits. These markers serve as detectable indicators that mediate the selection process, allowing breeders to efficiently identify and propagate plants that have successfully incorporated desired transgenic or mutant traits without having to rely on time-consuming phenotypic observation.
3Quantity of substance
If soybean cultivars are developed to maximize grain production and supply food, then higher seed yield is achieved, but the process requires efficient resource use and precise planning
Solution Approach 1:
The patent replaces complex manual breeding management with molecular marker-based selection systems. This substitution simplifies the breeding program by providing objective, DNA-based criteria for selecting high-yielding plants, reducing the need for complex phenotypic evaluation and precise manual planning while maximizing seed yield through genetically superior cultivars.
