Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to variability in resulting soybean lines.
Innovation Solution
The development of the soybean variety 01051641, which incorporates specific genetic loci through backcrossing and genetic transformation to confer traits like herbicide resistance, disease resistance, and modified fatty acid composition, allowing for the creation of stable and high-yielding soybean plants with improved agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties, then genetic diversity can be maintained, but the breeding process becomes time-consuming and unpredictable with high variability in resulting lines
Solution Approach 1:
The patent replaces conventional mechanical breeding methods (cross-pollination, selection, and generation advancement) with genetic engineering techniques. Specifically, it uses backcrossing combined with molecular marker-assisted selection to precisely introduce desired traits (such as disease resistance genes) into elite soybean backgrounds, dramatically reducing the time required and increasing predictability of breeding outcomes while maintaining genetic diversity through controlled introgression
2Productivity
If conventional breeding methods are employed to combine multiple desirable traits, then genetic variability is preserved, but the complexity and time required to achieve stable varieties increases significantly
Solution Approach 1:
The patent introduces molecular markers as intermediaries to facilitate trait selection and combination. By using DNA markers linked to desired traits (such as disease resistance genes), breeders can selectively combine multiple traits in the background of elite soybean varieties without the complexity of traditional multi-generational selection, thereby improving breeding efficiency while managing program complexity through molecular guidance
3Manufacturing precision
If backcrossing and genetic transformation are used to introduce specific traits, then breeding precision and predictability improve, but the genetic diversity and adaptability may be reduced
Solution Approach 1:
The patent applies local quality by introducing specific desired traits (such as disease resistance or herbicide tolerance) into an elite soybean genetic background through backcrossing, while maintaining the overall adaptability and genetic quality of the parent variety. This allows precise modification of specific loci without compromising the global adaptability and performance characteristics of the soybean variety
