Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to significant research costs and variability in results.
Innovation Solution
The development of the soybean variety D402501, which incorporates a single locus conversion through genetic transformation, conferring traits like herbicide resistance, disease resistance, and improved nutritional quality, and can be propagated using methods like backcrossing and hybridization to produce consistent and superior soybean plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties with desirable traits, then disease resistance and drought tolerance can be achieved, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies parameter changes by modifying the genetic composition of soybean plants through introduction of specific genes (e.g., Rps genes for disease resistance, drought tolerance genes) rather than relying on traditional breeding. This direct genetic modification changes the fundamental parameter of genetic makeup to achieve desired traits more rapidly and predictably than conventional breeding methods.
2Reliability
If conventional breeding techniques are used to develop soybean varieties with desirable traits, then improved nutritional quality can be achieved, but research costs increase significantly
Solution Approach 1:
The patent modifies nutritional quality parameters by introducing specific genes that control oil composition (e.g., genes affecting linoleic acid, linolenic acid content) and protein content. This direct genetic approach to changing nutritional parameters reduces the need for lengthy breeding programs and associated research costs compared to conventional breeding methods.
3Reliability
If single locus conversion through genetic transformation is used, then herbicide resistance and disease resistance can be conferred, but the complexity of the transformation process increases
Solution Approach 1:
The patent extracts and isolates specific resistance genes (such as Rps genes for disease resistance and herbicide resistance genes) and introduces them individually into the soybean genome through genetic transformation. This extraction approach allows for precise introduction of only the necessary resistance traits without the complexity of managing multiple genetic modifications, simplifying the overall transformation process while achieving reliable resistance.
4Stability of the object's composition
If backcrossing and hybridization methods are used to propagate soybean variety D402501, then consistent and superior soybean plants can be produced, but the breeding program complexity increases
Solution Approach 1:
The patent employs preliminary action by first creating the genetically modified soybean variety D402501 with desired traits through transformation, then using backcrossing and hybridization to propagate and stabilize these traits in subsequent generations. This preliminary genetic modification followed by systematic breeding ensures consistent production of superior plants while managing program complexity through a structured approach.
