Soybean Variety 5PHSB14 for Stable Multi-Trait Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of stable, high-yielding soybean varieties that are agronomically sound and possess desirable traits such as disease resistance, drought tolerance, and improved compositional traits is a time-consuming process requiring precise planning and resource efficiency, with existing methods taking six to twelve years from cross to delivery.
Innovation Solution
The introduction of the novel soybean variety 5PHSB14, which combines desirable traits like resistance to diseases and insects, tolerance to drought and heat, and improved agronomic characteristics, through methods of crossing, introgression of transgenic or mutant traits, and characterization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the variety achieves stability and agronomic soundness, but the development time becomes excessively long (six to twelve years)
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parent lines with specific desirable traits (disease resistance, drought tolerance, yield components) before crossing. This advance preparation of genetically superior parent material accelerates the breeding process while maintaining variety stability, reducing the overall development time from six to twelve years to a more efficient timeline.
2Productivity
If multiple desirable traits are combined in a single variety, then the agronomic performance and yield are improved, but the breeding process complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding process into distinct stages: selecting parent lines with specific traits, performing controlled crosses, evaluating F1 progeny for desired characteristics, and advancing superior lines through generations. This systematic breakdown of multi-trait combination into manageable steps reduces breeding process complexity while achieving high productivity through cumulative trait accumulation.
Solution Approach 2:
The patent applies local quality by focusing on specific geographic regions and environmental conditions when evaluating and selecting for particular traits. Different parent lines are selected and crossed based on their performance in specific locales, allowing the breeding program to optimize for regional agronomic needs while maintaining overall variety stability and productivity.
3Productivity
If precise planning and resource efficiency are maintained throughout the breeding process, then the variety development becomes more efficient, but the ability to adapt to changing program goals becomes limited
Solution Approach 1:
The patent applies dynamics by implementing a flexible breeding program structure where parent line selection, crossing strategies, and evaluation criteria can be dynamically adjusted based on emerging scientific knowledge, changing market demands, or new disease pressures. This dynamic approach maintains breeding efficiency through structured processes while preserving adaptability to program goal changes throughout the development timeline.
