Soybean Cultivar Breeding With Pre-Introduced Trait Combinations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars lack improved traits such as higher seed yield, disease resistance, drought tolerance, and altered fatty acid profiles, which are essential for enhancing agricultural productivity and nutritional value.
Innovation Solution
Development of a new soybean cultivar 22080703, which includes genetic modifications for herbicide tolerance, disease resistance, and improved fatty acid composition, achieved through methods like mutagenesis and transformation, combined with traditional breeding techniques to introduce desirable traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding techniques are used to develop new soybean cultivars, then genetic diversity is maintained, but the development process takes six to twelve years and requires multiple crossing generations
Solution Approach 1:
The patent applies preliminary action by using mutagenesis and transformation techniques to pre-introduce desired traits into the soybean germplasm before traditional breeding begins. This allows the breeder to start with plants that already possess target characteristics (such as disease resistance or altered fatty acid profiles), significantly reducing the time required for multiple crossing generations while maintaining genetic stability through controlled mutation and transformation processes
2Ease of manufacture
If conventional soybean cultivars are used, then breeding processes are simple and well-established, but the cultivars lack improved traits such as higher seed yield, disease resistance, and altered fatty acid profiles
Solution Approach 1:
The patent applies parameter changes by deliberately modifying key biological parameters of the soybean cultivar through mutagenesis and transformation. This includes changing fatty acid composition (altering the biochemical parameters of seed oil), introducing disease resistance genes (changing physiological parameters), and selecting for higher yield traits. These controlled parameter changes enable the development of superior cultivars that maintain breeding simplicity while achieving improved productivity and nutritional value
3Adaptability or versatility
If multiple crossing generations are performed to combine desirable traits, then trait combination is achieved, but resource consumption increases and direction changes are required
Solution Approach 1:
The patent applies preliminary action by pre-combining desirable traits through mutagenesis and transformation before the traditional crossing process begins. This allows the breeder to start with plants that already possess multiple desired characteristics in a single genotype, eliminating the need for multiple crossing generations to combine traits. Consequently, resource consumption is reduced while maintaining the ability to achieve complex trait combinations
