Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as high yield, disease resistance, and adaptability to various conditions, but existing methods are slow and prone to directional changes.
Innovation Solution
The introduction of soybean variety 5PEAA48, which is self-pollinated to ensure homozygosity and phenotypic stability, along with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce stable, high-yielding soybeans with improved agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean variety development methods are used, then desirable traits can be combined in a single variety, but the process takes six to twelve years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by self-pollinating soybean plants for multiple generations before crossing to establish homozygous lines with stable, fixed traits. This preliminary stabilization of parental lines ensures that desired traits are reliably combined in the final variety without requiring extended breeding time to correct genetic variability later in the process
2Reliability
If traditional soybean variety development methods are used, then desirable traits can be combined in a single variety, but the process requires extensive resources and precise planning
Solution Approach 1:
The patent applies self-service by utilizing self-pollination mechanisms inherent to soybean plants to maintain genetic stability and trait consistency. This eliminates the need for complex人工 intervention and resource-intensive monitoring systems required in traditional cross-breeding programs, reducing overall resource consumption while maintaining reliable trait combination
3Stability of the object's composition
If traditional soybean variety development methods are used, then stable high-yielding varieties can be developed, but the process is prone to changes in direction and requires minimal changes
Solution Approach 1:
The patent applies parameter changes by systematically controlling the self-pollination generation number and homozygosity levels to achieve optimal stability. By adjusting these genetic parameters through defined breeding steps, the method achieves variety stability without requiring extensive directional changes or corrections during the breeding process, thereby improving overall breeding efficiency
