Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in soybean breeding is to develop stable, high-yielding varieties that are resistant to diseases and abiotic stresses, with improved fatty acid profiles and agronomic characteristics, while also being efficient in resource use and time-consuming processes.
Innovation Solution
The development of the soybean variety XB38AT13, which combines desirable traits such as resistance to diseases, drought tolerance, and improved fatty acid composition through careful breeding and selection, allowing for the production of seeds with enhanced agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding processes are used to develop new varieties with multiple desirable traits, then disease resistance and drought tolerance are improved, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits (disease resistance, drought tolerance, fatty acid profiles) before crossing. This advance preparation of germplasm with known characteristics accelerates the breeding process by reducing the need for extensive screening and selection in later generations.
Solution Approach 2:
The patent utilizes parameter changes by focusing on specific measurable traits such as fatty acid composition (oleic, linoleic, linolenic acid percentages), disease resistance scores, and drought tolerance metrics. By defining and selecting for specific parameter ranges, the breeding process becomes more efficient and targeted rather than relying on traditional phenotypic selection alone.
2Productivity
If multiple traits are combined in a single soybean variety through breeding, then agronomic performance is improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct stages: selection of parental lines with specific traits, controlled crossing to combine traits, and systematic evaluation of progeny. This segmented approach allows each trait (yield, disease resistance, drought tolerance, fatty acid profile) to be addressed in a structured manner, reducing overall program complexity.
Solution Approach 2:
The patent employs universality by developing a multi-purpose breeding framework that simultaneously addresses multiple objectives: improving yield, enhancing disease resistance, increasing drought tolerance, and modifying fatty acid profiles. The same breeding population and selection criteria are used to achieve multiple traits, rather than requiring separate breeding programs for each trait.
3Stability of the object's composition
If extensive screening and selection are performed to ensure trait stability, then variety uniformity is improved, but resource efficiency decreases
Solution Approach 1:
The patent replaces traditional mechanical/phenotypic screening methods with molecular marker-based selection. By using DNA markers linked to desirable traits, the program can screen for trait stability and inheritance without extensive phenotypic evaluation, significantly reducing resource requirements while maintaining or improving selection accuracy and trait stability.
