Wheat Variety 6PHEQ26B Trait Integration via Preliminary Action
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 and baking qualities, necessitating the development of a new variety that addresses these needs.
Innovation Solution
The development of the wheat variety 6PHEQ26B, which is homozygous and stable, combining traits like disease resistance, drought tolerance, and improved milling and baking characteristics through selective breeding and genetic modification, including methods like backcrossing and transformation to introduce desired traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wheat breeding is used to combine desirable traits, then trait combination is achieved, but the process requires numerous steps and significant intervention
Solution Approach 1:
The patent applies preliminary action by pre-establishing a set of desirable traits in the parental germplasm before the actual breeding process. The parental lines are selected and prepared in advance with specific combinations of traits (disease resistance, drought tolerance, yield potential, milling qualities), which then serve as the foundation for generating the new variety through controlled crosses and selection, thereby reducing the complexity of subsequent breeding steps
2Reliability
If multiple desirable traits are combined in a single variety, then variety performance is improved, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: parental germplasm development, controlled crossing, progeny evaluation, and variety release. Each phase focuses on specific traits (e.g., disease resistance in one phase, yield in another), allowing systematic progress and reducing the overall time required compared to attempting to combine all traits simultaneously in a single unstructured process
3Adaptability or versatility
If conventional breeding methods are used, then trait combination is achieved, but significant intervention is required at multiple steps
Solution Approach 1:
The patent applies self-service by utilizing the natural self-pollinating characteristic of wheat to facilitate trait combination. The breeding process leverages wheat's inherent ability to self-pollinate, reducing the need for complex人工 pollination techniques and minimizing intervention requirements. This natural mechanism serves the breeding objective of combining traits from parental lines while simplifying the overall process
