Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheat varieties often lack a balanced combination of desirable traits such as high 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 6PNEK06B, which is homozygous and stable, combined with methods for genetic modification and cross-breeding to introduce traits like herbicide resistance, disease resistance, and altered nutritional content, using techniques like CRISPR/Cas system for genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing wheat varieties are used, then they have basic agricultural functionality, but they lack a balanced combination of desirable traits such as high seed yield, disease resistance, and improved milling properties
Solution Approach 1:
The patent combines multiple desirable traits from different parental germplasm into a single wheat variety through systematic breeding programs. This includes integrating high seed yield, disease resistance, drought tolerance, and improved milling properties into variety 6PNEK06B, creating a unified genotype that expresses all these traits simultaneously.
Solution Approach 2:
The wheat variety 6PNEK06B is designed to perform multiple functions across different agricultural conditions and uses. It serves as both a high-yielding crop variety and a source of beneficial traits for breeding programs, while also demonstrating adaptability to various environmental stresses, making it universally applicable.
2Adaptability or versatility
If genetic modification techniques are used to introduce desirable traits, then trait diversity is improved, but development complexity increases
Solution Approach 1:
The breeding program segments the development process into distinct phases: identifying parental lines with specific desirable traits, performing controlled crosses, selecting progeny with target traits, and validating performance across multiple environments. This systematic segmentation manages complexity by breaking down the overall breeding objective into manageable steps.
Solution Approach 2:
The patent employs preliminary characterization of parental germplasm to identify lines with specific desirable traits before initiating crosses. This preliminary action includes evaluating parents for disease resistance, yield potential, and milling properties, ensuring that only parents with confirmed beneficial traits are used in the breeding program, thereby streamlining subsequent development.
