Soybean Cultivar S170028 Breeding Protocol
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 high 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 S170028, which allows for methods such as selfing, backcrossing, and transformation to produce plants with superior characteristics, including resistance to glyphosate and isoxaflutole herbicides, and the use of regenerable cells in tissue culture to maintain morphological and physiological traits, enabling the introgression of transgenic or mutant traits and the creation of variants through mutagenesis or transformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then stable high-yielding cultivars can be developed, but the process takes 6-12 years and requires precise forward planning with minimum changes in direction
Solution Approach 1:
The patent applies preliminary action by pre-establishing a standardized breeding protocol with defined parental selections, crossing schemes, and evaluation criteria. The multi-year breeding program is planned in advance with specific generations (F1, F2, F3, etc.) and selection steps predetermined, allowing the breeding process to proceed systematically without delays from mid-course corrections. This preliminary planning enables efficient progression through generations while maintaining trait stability.
2Adaptability or versatility
If multiple desirable traits are combined in a single cultivar, then superior agronomic quality is achieved, but the breeding process becomes more complex requiring efficient resource use
Solution Approach 1:
The patent applies segmentation by dividing the complex multi-trait breeding process into distinct generational stages (F1 hybrid production, F2 population development, F3-F5 selection and advancement). Each generation has specific objectives: F1 establishes hybrid vigor, F2 separates and recombines traits, F3-F5 progressively select and fix desired characteristics. This segmentation allows breeders to focus on one set of traits at each stage rather than managing all traits simultaneously, reducing overall process complexity while achieving multiple desirable traits in the final cultivar.
3Reliability
If transgenic or mutant traits are introduced into soybean cultivars, then resistance to diseases and abiotic stresses is improved, but existing methods are limited in efficiently introgressing these traits
Solution Approach 1:
The patent applies the intermediary principle by using a standardized breeding cultivar as a mediator to introgress transgenic or mutant traits into elite soybean lines. The breeding protocol serves as an intermediary system that facilitates the integration of foreign or mutant genes through controlled crosses and systematic backcrossing. This intermediary breeding approach streamlines the complex process of trait introgression by providing a standardized framework for selection and advancement, making it easier to efficiently incorporate disease resistance and stress tolerance traits into high-performing cultivars.
