Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean varieties lack improved combinations of traits such as higher seed yield, disease resistance, insect resistance, drought tolerance, heat tolerance, better agronomic quality, and enhanced compositional traits, which are essential for maximizing grain production and meeting the demands of food and animal feed.
Innovation Solution
Development of the novel soybean variety 01106402, which incorporates genetic modifications and crosses to enhance traits like herbicide resistance, disease resistance, and improved nutritional quality, utilizing methods like genome editing with engineered nucleases and traditional breeding techniques to create stable, high-yielding soybean plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding techniques are used to develop soybean varieties, then genetic diversity and trait combination are improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (herbicide resistance, disease resistance, yield characteristics) before crossing. The parental germplasm is carefully chosen and characterized in advance, allowing the breeding program to start with optimized genetic combinations rather than creating diversity from scratch, thus reducing overall breeding time.
Solution Approach 2:
The patent employs feedback mechanisms through systematic evaluation of breeding progeny for desired traits. Performance data from field trials and genetic analysis are fed back into the breeding program to guide selection decisions, allowing rapid identification and advancement of superior lines while eliminating inferior combinations, thereby reducing the time required to develop improved varieties.
2Reliability
If multiple traits are combined in a single variety, then agronomic quality and resistance are improved, but genetic complexity and breeding difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct modules: one parental line contributes herbicide resistance traits, another contributes disease resistance, and a third contributes yield characteristics. Each trait complex is developed and stabilized separately in different parental lines before being combined through controlled crossing, making the overall complex breeding goal manageable through systematic segmentation of genetic contributions.
Solution Approach 2:
The patent applies local quality by ensuring each parental line is optimized for specific local requirements - some lines are selected for resistance to particular diseases prevalent in certain regions, others for herbicide resistance matching local weed pressure, and others for yield potential in specific growing conditions. This allows the final variety to have targeted, region-appropriate trait combinations without unnecessary genetic complexity.
3Productivity
If herbicide resistance is introduced through genetic modification, then weed control effectiveness is improved, but public acceptance and regulatory complexity worsen
Solution Approach 1:
The patent uses conventional breeding techniques as an intermediary approach to achieve herbicide resistance. Rather than directly introducing foreign genes through genetic modification, the program uses cross-breeding between soybean varieties that naturally possess or have been traditionally bred for herbicide tolerance. This intermediary method achieves the same productivity goal (herbicide-resistant soybeans) while avoiding the regulatory and public acceptance issues associated with direct genetic modification.
