Soybean Cultivar S140150 Breeding via Segmentation and Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean cultivar development is time-consuming and requires precise planning, involving multiple years to combine desirable traits such as high seed yield, disease resistance, drought tolerance, and improved fatty acid profile, which poses challenges in efficiently producing stable and agronomically sound soybean cultivars.
Innovation Solution
Development of the soybean cultivar S140150, which includes methods for introgressing transgenic or mutant traits, using regenerable cells in tissue culture, and crossing with other cultivars to produce superior F1 hybrid seeds with enhanced characteristics, along with the introduction of specific genes for herbicide resistance, disease resistance, and modified fatty acid metabolism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean cultivar development methods are used to combine desirable traits, then stable and agronomically sound cultivars are produced, but the process takes six to twelve years and requires precise forward planning
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental germplasm with specific desirable traits (high seed yield, disease resistance, drought tolerance, improved fatty acid profile) before crossing. This advance preparation of parental lines with known characteristics accelerates the breeding process while maintaining cultivar stability, as the parent selection is done systematically before the actual cross-breeding begins
2Adaptability or versatility
If multiple desirable traits are combined in a single cultivar, then superior agronomic performance is achieved, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent applies segmentation by dividing the multi-trait breeding process into distinct phases: (1) selection of parental germplasm with specific traits, (2) crossing to combine traits, (3) evaluation of progeny for desired characteristics, and (4) stabilization of the cultivar. This segmented approach manages complexity by handling one trait combination at a time rather than attempting to combine all traits simultaneously
Solution Approach 2:
The patent applies local quality by selecting parental lines that each excel in specific local traits (one parent for high yield, another for disease resistance, another for fatty acid profile). Each parent contributes its specialized strength to the cross, allowing the final cultivar to accumulate diverse desirable traits while the breeding process remains manageable through focused selection criteria
3Productivity
If traditional breeding methods are used to improve seed yield and quality, then agronomically sound cultivars are developed, but the process requires efficient use of resources and minimum changes in direction
Solution Approach 1:
The patent applies feedback by systematically evaluating progeny at each breeding stage for key characteristics (seed yield, disease resistance, fatty acid profile) and using this information to guide subsequent crossing decisions. This feedback loop ensures that breeding resources are directed toward combinations that demonstrably improve productivity, rather than pursuing unguided crosses that may waste resources
