Soybean Variety Breeding for Multi-Resistance and Yield Stability
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, and herbicide resistance, which are essential for maximizing grain production and meeting the demands of food and agricultural sustainability.
Innovation Solution
Development of the novel soybean variety 01094692, which incorporates genetic modifications and locus conversions for herbicide resistance, disease resistance, and improved agronomic qualities through a breeding process involving cross-pollination and genetic engineering techniques, including the use of engineered nucleases for precise genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used, then variety development is straightforward, but improved combinations of traits (yield, disease resistance, insect resistance, drought tolerance, herbicide resistance) cannot be achieved
Solution Approach 1:
The patent combines multiple desirable traits from different parental lines into a single soybean variety through controlled cross-pollination. The breeding program integrates disease resistance, insect resistance, drought tolerance, and herbicide resistance traits simultaneously, creating a unified variety that expresses all these improved characteristics together rather than separately.
Solution Approach 2:
The patent employs genetic engineering techniques including engineered nucleases to precisely modify genomic parameters and introduce specific trait improvements. This allows for targeted changes in genetic parameters to achieve enhanced disease resistance, herbicide resistance, and other desirable traits while maintaining overall variety performance.
2Adaptability or versatility
If multiple trait improvements are pursued simultaneously, then agronomic quality improves, but breeding program complexity increases
Solution Approach 1:
The breeding program is divided into distinct phases and components: parental line selection, controlled cross-pollination, progeny evaluation, and trait verification. Each phase focuses on specific objectives, allowing complex multi-trait improvement to be managed through systematic segmentation of the breeding process into manageable steps.
Solution Approach 2:
The patent develops a breeding approach that can simultaneously target multiple trait types (disease resistance, insect resistance, abiotic stress tolerance, herbicide resistance) using a unified methodology. The same cross-pollination and selection framework applies across different trait categories, reducing overall program complexity despite the multiplicity of goals.
