Soybean Cultivar S170002 Breeding Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming process that requires precise planning and resource management, aiming to combine desirable traits such as high seed yield, disease resistance, drought tolerance, and improved fatty acid profiles, while existing methods are inefficient in achieving these goals.
Innovation Solution
The introduction of soybean cultivar S170002, which includes methods for crossing, mutagenesis, and transformation to introduce transgenic or mutant traits, such as resistance to glyphosate and isoxaflutole herbicides, and the use of regenerable cells in tissue culture to produce plants with superior characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the cultivar achieves stability and uniformity, but the development process takes 6-12 years and is highly time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with specific desirable traits (high seed yield, disease resistance, drought tolerance, improved fatty acid profiles) before crossing. This advance preparation and selection of parents with known characteristics accelerates the breeding process while maintaining cultivar stability and uniformity in the offspring.
2Productivity
If multiple desirable traits are combined in a single cultivar, then the agronomic quality and yield are improved, but the breeding program complexity and resource requirements increase
Solution Approach 1:
The patent merges multiple desirable traits (high seed yield, disease resistance, drought tolerance, improved fatty acid profiles) into a single soybean cultivar through controlled crossing of parental lines that each contribute specific traits. This combining approach achieves superior agronomic quality and productivity while managing breeding program complexity through systematic trait integration.
Solution Approach 2:
The resulting soybean cultivar exhibits multi-functionality by simultaneously providing high seed yield, resistance to multiple diseases, tolerance to drought stress, and improved fatty acid composition. This universal cultivar meets multiple agronomic goals and production requirements in a single variety, reducing the need for separate breeding programs for each trait.
3Productivity
If precise forward planning and resource management are implemented in breeding programs, then the efficiency is improved, but the initial planning complexity and resource allocation requirements increase
Solution Approach 1:
The patent implements precise forward planning by pre-defining breeding objectives, selecting appropriate parental lines with specific traits, and outlining the crossing and selection procedures before initiating the breeding program. This preliminary planning and resource allocation improve breeding efficiency by reducing delays and ensuring optimal use of materials and facilities throughout the 6-12 year development cycle.
