6PMZM22B Wheat Variety Through Backcrossing and Locus Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheat varieties lack a comprehensive combination of desirable traits such as higher seed yield, disease resistance, drought and heat tolerance, altered milling properties, and improved agronomic characteristics, limiting their adaptability and commercial utility.
Innovation Solution
Development of the wheat variety 6PMZM22B, which is homozygous and stable, incorporating genetic modifications and locus conversions to introduce traits like herbicide resistance, disease resistance, and altered nutritional quality, achieved through methods like genetic transformation and backcrossing, ensuring uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wheat breeding methods are used, then variety development is straightforward, but the combination of desirable traits (yield, disease resistance, stress tolerance, milling properties) is insufficient
Solution Approach 1:
The patent combines multiple desirable traits from different parental lines into a single wheat variety 6PMZM22B, merging disease resistance, stress tolerance, and improved agronomic characteristics that were previously分散 in different varieties
Solution Approach 2:
The wheat variety 6PMZM22B is developed to perform multiple functions simultaneously: it provides high yield, disease resistance, stress tolerance, and improved milling properties, making it a universal solution for multiple agricultural challenges
2Reliability
If genetic modifications are introduced to improve traits, then adaptability and resistance are enhanced, but variety complexity increases
Solution Approach 1:
The patent uses backcrossing as an intermediary method to transfer specific desirable traits from donor parents to the recurrent parent 22B, allowing gradual introduction of resistance genes without complete genetic replacement
Solution Approach 2:
The wheat variety 6PMZM22B introduces specific local improvements at targeted genetic loci for disease resistance and stress tolerance while maintaining the overall genetic background and agronomic characteristics of the parent variety
