Soybean Cultivar S170108 Breeding Program
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as higher seed yield, disease resistance, drought tolerance, and improved fatty acid profile, while existing methods are limited in efficiently introducing transgenic or mutant traits into soybean cultivars.
Innovation Solution
The introduction of soybean cultivar S170108, which allows for selfing, backcrossing, and crossing with other cultivars to produce superior hybrid seeds, along with methods for introgressing transgenic or mutant traits, and the use of regenerable cells in tissue culture to produce plants with specific morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the cultivar achieves stable inheritance of traits, but the development process takes 6-12 years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by pre-establishing a structured breeding program with defined objectives, selected parental germplasm, and planned crossing schemes before actual breeding begins. This forward planning includes identifying target traits, selecting appropriate parents with complementary characteristics, and designing the breeding pathway in advance, which streamlines the 6-12 year process and reduces wasted time and resources.
2Adaptability or versatility
If multiple crossing and selection steps are performed to combine desirable traits, then the cultivar achieves superior trait combination, but the process requires precise forward planning and efficient resource use with minimum changes in direction
Solution Approach 1:
The patent segments the complex breeding process into distinct, manageable phases: (1) parental selection based on specific criteria, (2) controlled crossing to generate F1 hybrids, (3) systematic selection and evaluation of progeny, and (4) backcrossing or selfing to stabilize traits. Each phase has specific objectives and selection criteria, making the overall complex process more controllable and efficient.
Solution Approach 2:
The patent employs universal breeding protocols and evaluation methods that can be applied across different soybean cultivars and trait combinations. The standardized approach to crossing, selection, and trait evaluation creates a multi-functional framework that handles various breeding objectives (yield improvement, disease resistance, quality enhancement) through a consistent process, reducing the need for frequent changes in breeding direction.
3Reliability
If conventional breeding methods are used to improve seed yield and quality, then the cultivar achieves agronomic soundness, but the process is time-consuming and requires efficient resource use
Solution Approach 1:
The patent incorporates systematic feedback mechanisms throughout the breeding process, including field performance evaluation, trait assessment, and data recording at each generation. This feedback allows breeders to monitor progress toward breeding objectives, identify promising lines early, and make informed decisions about which genotypes to advance or discard, thereby improving breeding productivity while maintaining agronomic soundness through continuous evaluation.
