Solution Overview
Problem
Existing wheat varieties often lack a balanced combination of desirable traits such as higher seed yield, disease resistance, drought tolerance, and improved milling properties, making them less adaptable to various agricultural conditions and uses.
Innovation Solution
Development of the wheat variety 6PDHJ97B, which is homozygous and stable, with the ability to incorporate genetic modifications or locus conversions for traits like herbicide resistance, disease resistance, and altered nutritional content through methods like genetic transformation and backcrossing, enabling the introduction of specific traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple desirable traits (high seed yield, disease resistance, drought tolerance, heat tolerance, improved milling and baking properties) are combined in a single variety, then the overall performance and versatility of the wheat variety is improved, but the complexity of breeding and genetic modification processes increases
Solution Approach 1:
The patent combines multiple desirable traits including high seed yield, disease resistance, drought tolerance, heat tolerance, and improved milling and baking properties into a single wheat variety (6PDHJ97B). This merging of previously separate or conflicting traits into one integrated variety directly resolves the technical contradiction by achieving enhanced versatility while managing the complexity through systematic breeding approaches.
Solution Approach 2:
The developed wheat variety serves multiple functions and applications simultaneously - it can be used for food production, industrial processing, and is adapted to various environmental conditions. This multi-functionality approach allows the single variety to address diverse needs, thereby improving adaptability and versatility as required by the technical contradiction.
2Reliability
If wheat varieties are developed through extensive breeding and genetic modification, then desirable traits are improved, but the time required for development increases
Solution Approach 1:
The patent employs preliminary action by using pre-selected parental lines with desirable traits and pre-prepared genetic modification protocols. The breeding program utilizes previously identified and characterized genetic resources, allowing the development process to proceed more efficiently. This preliminary preparation of breeding materials and protocols reduces the overall development time while maintaining the reliability of trait improvement.
Solution Approach 2:
The patent employs intermediary techniques such as genetic markers and molecular tools to facilitate the breeding process. These intermediaries enable more precise selection and tracking of desirable traits during breeding generations, reducing the time required to achieve stable trait combinations. The use of molecular markers as intermediaries allows for accelerated breeding cycles while maintaining the reliability of trait inheritance.
3Stability of the object's composition
If conventional breeding methods are used to develop new wheat varieties, then genetic diversity is maintained, but the speed of trait accumulation and variety development is slow
Solution Approach 1:
The patent replaces conventional mechanical breeding methods with molecular and genetic tools. Instead of relying solely on traditional cross-pollination and selection processes, the patent incorporates genetic modification techniques and molecular markers to accelerate trait accumulation. This substitution of mechanical breeding processes with molecular approaches maintains genetic diversity while significantly increasing the speed of variety development.
Solution Approach 2:
The patent utilizes parameter changes by introducing and manipulating specific genetic parameters through molecular tools and genetic modification. By changing the genetic parameters of the wheat varieties through controlled introduction of desirable traits via molecular techniques, the patent accelerates the accumulation of beneficial characteristics while maintaining genetic diversity through careful parameter management and selection.
