Soybean Cultivar S170174 Transgenic Trait Introduction
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 S170174, which allows for methods like selfing, backcrosses, and hybrid production, along with genetic transformation techniques using expression vectors and biolistic delivery, to introduce transgenic traits conferring herbicide resistance, disease resistance, and improved agronomic qualities, and the use of regenerable cells in tissue culture to produce plants with specific characteristics.
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 over time, but the process takes 6-12 years and requires precise forward planning with minimum changes in direction
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental germplasm with specific desirable traits (disease resistance, yield potential, fatty acid profile) before initiating the breeding program. This advance preparation of parental material with known characteristics accelerates the breeding process while maintaining trait stability, as the foundation genetics are already optimized before crossing begins
2Adaptability or versatility
If transgenic or mutant traits are introduced into soybean cultivars, then herbicide resistance and disease resistance can be achieved, but existing methods are limited in efficiency
Solution Approach 1:
The patent uses molecular markers as intermediaries to facilitate the introduction of transgenic and mutant traits. These markers serve as detectable proxies for desired traits, enabling selective breeding and acceleration of trait incorporation. The markers mediate between the genetic modification and the phenotypic expression, allowing for more efficient selection and faster productivity in introducing diverse traits
3Adaptability or versatility
If multiple desirable traits are combined in a single cultivar, then higher seed yield, disease resistance, and improved fatty acid profile are achieved, but the breeding program becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: parental selection, crossing, molecular marker screening, and trait validation. Each phase focuses on specific traits and uses appropriate methods, reducing overall program complexity. The breeding process is segmented into manageable stages with clear objectives, making it easier to track progress and maintain multiple desirable traits simultaneously
