Soybean Cultivar 21440700 Breeding for Stable Multi-Trait Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean cultivars face challenges in combining desirable traits such as high 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 21440700 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 to produce plants with specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine multiple desirable traits (high seed yield, disease resistance, drought tolerance, altered fatty acid profiles), then the cultivar achieves improved agronomic quality and stability, but the development process becomes time-consuming (6-12 years) and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits (high seed yield, disease resistance, altered fatty acid profiles) before crossing. The parental germplasm is carefully chosen and prepared in advance with known characteristics, allowing the breeding program to start from a optimized foundation rather than exploring random variations, thus reducing the overall time to develop stable cultivars.
2Adaptability or versatility
If multiple breeding objectives are pursued simultaneously (seed yield, disease resistance, drought tolerance, fatty acid composition), then the final cultivar achieves superior agronomic quality, but the program complexity and difficulty of management increase
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into distinct phases and objective groups. Different parental lines are selected for specific trait combinations (e.g., one parent for disease resistance, another for fatty acid composition), and crossing objectives are segmented into manageable stages. This allows each breeding objective to be pursued systematically through dedicated parental selections and targeted crosses, reducing overall program complexity.
Solution Approach 2:
The patent applies universality by developing parental germplasm that serves multiple breeding objectives simultaneously. Parental lines are selected and characterized to possess combinations of desirable traits (e.g., a parent line with both high seed yield and disease resistance), allowing a single parental source to contribute to multiple cultivar improvement goals, thereby simplifying the breeding program structure.
3Productivity
If precise forward planning and resource allocation are implemented in breeding programs, then cultivar development efficiency improves, but the requirement for detailed program management and monitoring increases
Solution Approach 1:
The patent applies preliminary action by establishing detailed breeding plans and resource allocation strategies before initiating crossing programs. Parental lines are pre-characterized and selected based on specific breeding objectives, and crossing designs are predetermined with clear timelines and resource requirements. This upfront planning reduces the need for complex ongoing management adjustments while maintaining high breeding efficiency.
