Soybean Cultivar 28331162 Breeding for Stable Multi-Trait Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars face challenges in combining desirable traits such as higher seed yield, disease resistance, drought tolerance, and altered fatty acid profiles, which are time-consuming to develop and require precise planning and resource efficiency.
Innovation Solution
Development of a new soybean cultivar (28331162) with improved traits achieved through traditional breeding and genetic modification, including introgression of transgenic or mutant traits, and use of regenerable cells for tissue culture, along with methods for determining genotype and producing hybrid seeds with superior characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine desirable traits in soybean cultivars, then the cultivar can achieve improved seed yield, disease resistance, and altered fatty acid profiles, but the development process becomes time-consuming and requires precise forward planning with minimum changes in direction
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental germplasm with specific desirable traits (higher seed yield, disease resistance, altered fatty acid profiles) before initiating the breeding program. This forward planning ensures that the crossing program is directed toward specific goals from the outset, reducing unnecessary changes in direction and accelerating the development timeline while maintaining trait stability
2Adaptability or versatility
If multiple desirable traits are combined in a single soybean cultivar, then the agronomic quality and yield are improved, but the breeding program complexity increases requiring efficient resource use and precise planning
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: selection of parental germplasm with specific traits, controlled crossing to combine traits, and systematic evaluation of progeny. This segmentation of the breeding process into manageable stages reduces program complexity while efficiently combining multiple desirable traits including disease resistance, yield improvement, and fatty acid profile modification
3Productivity
If soybean cultivars are developed to maximize grain production, then food supply for animals and humans is improved, but the development process requires selecting and developing plants with superior traits that extends over multiple years
Solution Approach 1:
The patent applies self-service through self-pollination of selected parental plants to maintain and stabilize desirable traits within each parental line before crossing. This self-service approach ensures that each parent contributes stable, pure genetic material to the breeding program, accelerating the development of high-yielding cultivars by reducing the need for repeated selection cycles and minimizing development duration
