Soybean Variety 5PSTN09: Stable Yield Through Rapid Trait Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of stable, high-yielding soybean varieties that are resistant to diseases and insects, tolerant to drought and heat, and have improved agronomic characteristics is a time-consuming process requiring precise planning and resource efficiency, with existing methods taking six to twelve years from cross to delivery.
Innovation Solution
The introduction of the novel soybean variety 5PSTN09, which is self-pollinated for uniformity and stability, and can be bred or genetically modified to incorporate desired traits such as disease resistance, herbicide tolerance, and altered fatty acid profiles through backcrossing and transgenic methods, maintaining phenotypic and morphological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop new soybean varieties, then desirable traits can be combined in a single variety, but the development process takes six to twelve years from the time the first cross is made until the finished seed is delivered to the farmer
Solution Approach 1:
The patent applies preliminary action by using pre-developed inbred lines and advanced generation materials that have already been partially bred and evaluated. This allows the final variety development to start from a more advanced stage rather than from initial crosses, significantly reducing the time required to deliver finished seed to the farmer while maintaining the stability and reliability of the variety through controlled backcrossing and selection processes.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety through traditional breeding, then agronomic performance is improved, but the process requires precise planning and efficient use of resources with a minimum of changes in direction
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases and components: using pre-developed inbred lines, performing backcrossing to introduce specific traits, conducting multi-location evaluation, and maintaining separate breeding pools for different trait combinations. This segmented approach allows complex agronomic characteristics to be developed systematically while managing program complexity through structured organization and specialized personnel.
3Reliability
If soybean varieties are developed for high yield and stability across different conditions, then agronomic soundness is improved, but the process is time-consuming and requires continuous evaluation and selection
Solution Approach 1:
The patent applies feedback by implementing continuous multi-location evaluation and selection processes where breeding materials are tested under diverse environmental conditions, and performance data is used to feedback into subsequent selection decisions. This feedback mechanism ensures yield stability across different conditions while improving breeding efficiency by focusing resources on the most promising lines based on accumulated performance data.
