Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with improved traits such as disease resistance, drought tolerance, and herbicide resistance, which are difficult to predict and require extensive research efforts due to the complexity of genetic combinations and environmental factors.
Innovation Solution
The development of the soybean variety 01073354, which includes specific genetic modifications and locus conversions, such as those conferring herbicide resistance and disease resistance, achieved through genetic transformation and backcrossing techniques, allowing for the introduction of desired traits while maintaining the original variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity and trait combinations can be explored, but the process becomes time-consuming and unpredictable due to complex genetic combinations and environmental factors
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (herbicide resistance, disease resistance, yield characteristics) before initiating the breeding program. The parental germplasm is carefully chosen and characterized in advance, with specific traits already established, so that the crossing program can directly combine these pre-validated traits without needing to screen through numerous generations of random variation.
Solution Approach 2:
The patent implements feedback mechanisms through systematic evaluation and selection at multiple stages of the breeding program. Progeny are assessed for trait expression (herbicide resistance, disease resistance, yield), and only those meeting predetermined criteria advance to the next generation. This feedback loop allows rapid elimination of unwanted genetic combinations and accelerates the development of varieties with the desired trait profile.
2Adaptability or versatility
If multiple traits are combined in a single variety to improve agricultural productivity, then the variety becomes more versatile and productive, but the breeding program complexity and difficulty of achieving stable trait combinations increase
Solution Approach 1:
The patent applies segmentation by dividing the multi-trait breeding program into distinct modular components: herbicide resistance trait introduction, disease resistance trait introduction, yield improvement, and quality traits. Each trait is addressed through separate crossing events or backcrossing programs, allowing independent optimization and validation of each trait module before integrating them into the final variety.
Solution Approach 2:
The patent employs universality by developing a standardized breeding protocol that can be applied across multiple trait combinations. The same general approach (parental selection, crossing, progeny evaluation, selection, and stabilization) is used whether introducing herbicide resistance, disease resistance, or yield traits, making the breeding program systematic and scalable to different trait combinations without requiring entirely separate programs for each.
3Reliability
If extensive research efforts are invested to achieve stable high-yielding varieties with improved traits, then variety performance and reliability improve, but the resources and effort required increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-validating parental lines for specific traits (herbicide resistance, disease resistance, yield potential) before initiating the breeding program. This preliminary characterization ensures that only proven trait carriers are used as parents, reducing the need for extensive screening and validation in later generations and thereby reducing overall research effort while maintaining reliability.
Solution Approach 2:
The patent implements feedback through systematic evaluation at multiple checkpoints during the breeding program. Progeny are assessed for trait expression, genetic stability, and performance characteristics, with only those meeting predetermined criteria advancing. This feedback mechanism ensures reliable trait inheritance and variety stability while efficiently allocating research resources to promising lines rather than continuing to invest in all progeny equally.
