Find Innovative SolutionsGenerate Solutions
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 6PSPJ45B, 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, along with traditional breeding techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding techniques are used to develop wheat varieties, then genetic diversity is maintained, but the combination of desirable traits (yield, disease resistance, drought tolerance, milling properties) is limited and unstable
Solution Approach 1:
The patent applies parameter changes by utilizing genetic modifications and locus conversions to alter specific genetic parameters of the wheat variety. This allows precise modification of traits such as seed yield, disease resistance, drought tolerance, and milling properties while maintaining overall genetic stability through controlled breeding programs.
Solution Approach 2:
The patent creates a composite genetic structure by combining traditional breeding with genetic modification techniques. This results in a wheat variety that integrates both conventional genetic diversity and targeted genetic enhancements, achieving a balanced combination of adaptability and stability across multiple desirable traits.
2Manufacturing precision
If genetic modifications are introduced to improve specific traits, then trait precision is improved, but the complexity of breeding programs increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: traditional breeding to establish base varieties, genetic modification to introduce specific traits, and backcrossing to integrate modifications. This segmented approach allows precise trait improvement while managing program complexity through structured implementation.
Solution Approach 2:
The patent uses backcrossing as an intermediary technique to bridge genetic modification and traditional breeding. This intermediary process facilitates the integration of genetically modified traits into conventional breeding programs, reducing overall complexity by providing a systematic transition method.
3Adaptability or versatility
If multiple desirable traits are combined in a single variety, then versatility is improved, but the difficulty of achieving uniformity and stability increases
Solution Approach 1:
The patent applies preliminary action by establishing stable base varieties through traditional breeding before introducing genetic modifications. This preliminary foundation ensures uniformity and stability are achieved before adding complex traits, making the final combination of multiple desirable characteristics more manageable and consistent.
