Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits like disease resistance, drought tolerance, and improved fatty acid profiles, but face challenges in efficiently combining these traits in a single variety.
Innovation Solution
The development of a novel soybean variety, XB009E11, which is the result of careful breeding and selection, combining traits such as resistance to aerial web blight, aphid antibiosis, brown stem rot, and improved fatty acid profiles, through a comprehensive breeding program involving cross-pollination and genetic marker-assisted selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine multiple desirable traits in a single soybean variety, then the variety achieves improved disease resistance, drought tolerance, and fatty acid profiles, but the breeding process becomes extremely time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits (disease resistance, drought tolerance, fatty acid profiles) before crossing. This preliminary characterization and selection of parents with known trait profiles allows the breeding program to systematically combine traits without starting from random crosses, thereby reducing the time required to develop varieties with multiple desirable characteristics
2Productivity
If extensive cross-pollination and selection are performed to achieve stable, high-yielding varieties with multiple traits, then the variety achieves superior agronomic characteristics and yield, but the breeding program requires significant resources and multiple years of development
Solution Approach 1:
The patent implements feedback mechanisms through systematic evaluation and characterization of breeding lines at multiple stages. Performance data from field trials, molecular marker analysis, and trait assessment are fed back into the selection process to guide subsequent crossing decisions. This feedback-driven approach ensures that resources are concentrated on the most promising lines, optimizing the efficiency of resource utilization while developing high-yielding varieties with multiple traits
3Stability of the object's composition
If multiple generations of selection are conducted to fix desirable traits, then the variety achieves trait stability and uniformity, but the development process extends over six to twelve years
Solution Approach 1:
The patent replaces traditional mechanical phenotypic selection with molecular marker-assisted selection. By using DNA markers linked to desirable traits, breeders can identify and select for specific genes without waiting for phenotypic expression. This substitution accelerates the fixation of traits by allowing selection at the genetic level, significantly reducing the number of generations required to achieve trait stability and uniformity
