Soybean Variety 5PRNN46 Breeding Program Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as high yield, disease resistance, and tolerance to environmental stresses, while existing methods are inefficient and take around six to twelve years from the first cross to delivering finished seed to farmers.
Innovation Solution
The introduction of the novel soybean variety 5PRNN46, which includes methods for crossing, introgressing transgenic, mutant, or native traits, and characterizing soybean plants to produce stable, high-yielding varieties with improved agronomic characteristics, disease resistance, and environmental tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional breeding methods are used to develop new soybean varieties, then desirable traits can be combined in a single variety, but the development process takes 6-12 years and is time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-establishing a structured breeding program with defined objectives, selecting germplasm with desired traits before the actual crossing begins, and planning multiple generations of selection and evaluation in advance. This systematic preparation and forward planning enables the breeding process to proceed more efficiently and reduce overall development time while maintaining the combination of desirable traits.
2Productivity
If traditional breeding methods are used, then variety development can be achieved, but resource use is inefficient and requires extensive planning adjustments
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: germplasm selection, crossing design, generation-specific selection criteria, and evaluation stages. Each phase has specific objectives and resources allocated, allowing for more efficient resource management and reduced complexity through structured organization rather than monolithic planning.
Solution Approach 2:
The patent applies dynamics by establishing a flexible breeding program that can adapt to emerging data and conditions. The multi-generational selection process allows for dynamic adjustment of breeding objectives and resource allocation based on performance data, reducing the need for extensive initial planning while maintaining efficiency.
3Loss of time
If the breeding process is accelerated, then development time is reduced, but the stability and uniformity of the variety may be compromised
Solution Approach 1:
The patent applies continuity of useful action by implementing continuous selection and evaluation across multiple generations without interruption. Each generation builds upon the previous one with maintained selection criteria, ensuring that variety stability is preserved while the overall process is accelerated through parallel operations and efficient resource utilization across generations.
