Soybean Cultivar 21130721 for Stable Multi-Trait Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 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 management.
Innovation Solution
Development of a new soybean cultivar 21130721 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 (higher seed yield, disease resistance, drought tolerance, altered fatty acid profiles), then the cultivar achieves improved agronomic performance 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 germplasm with specific desirable traits (disease resistance, drought tolerance, altered fatty acid profiles) before crossing. This advance preparation of parental lines with known characteristics streamlines the breeding process and reduces the time required for trait combination and validation in subsequent generations.
2Productivity
If multiple desirable traits are combined in a single cultivar through breeding, then the agronomic quality and seed yield improve, but the breeding program complexity and resource requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct stages: selecting parental lines with specific traits, performing controlled crosses, and advancing progeny through generation cycles. This segmented approach allows systematic combination of multiple desirable traits (disease resistance, drought tolerance, fatty acid profiles) while managing program complexity through structured progression.
Solution Approach 2:
The patent applies local quality by selecting parental germplasm with specific localized traits (certain disease resistances, particular fatty acid compositions) and combining them in controlled crosses. This allows the final cultivar to possess multiple specialized qualities rather than general improvements, targeting specific agronomic needs.
3Ease of manufacture
If precise forward planning and efficient resource use are implemented in cultivar development, then the breeding process becomes more manageable, but the flexibility to make changes in direction is reduced
Solution Approach 1:
The patent applies dynamics by maintaining flexible breeding designs that allow directional changes. The controlled cross and progeny advancement system enables breeders to adjust selection criteria and breeding objectives based on emerging data and changing agronomic needs, providing adaptability within the structured breeding framework.
