Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheat cultivars lack improved combinations of desirable traits such as higher seed yield, disease and insect resistance, drought and heat tolerance, better agronomic quality, and herbicide resistance, which are essential for enhancing wheat productivity and versatility in various applications.
Innovation Solution
Development of the wheat cultivar 01095250, which includes a single locus conversion through genetic transformation to introduce transgenic genes conferring traits like herbicide resistance, disease resistance, insect resistance, and improved nutritional quality, combined with traditional breeding techniques to maintain morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding techniques are used to combine desirable traits, then morphological and physiological characteristics are maintained, but the ability to introduce transgenic traits is limited
Solution Approach 1:
The patent combines traditional breeding techniques with genetic transformation methods to create wheat cultivars that possess both transgenic traits and maintained morphological characteristics. This merging allows the integration of novel traits through transformation while using traditional breeding to stabilize and maintain the desired phenotype across generations.
Solution Approach 2:
The breeding program is designed to achieve multiple objectives simultaneously: introducing transgenic traits, maintaining morphological characteristics, and improving agronomic performance. This multi-functional approach allows a single breeding strategy to address diverse requirements for modern wheat cultivars.
2Productivity
If multiple desirable traits are combined in a single variety, then productivity and versatility are enhanced, but the complexity of breeding program increases
Solution Approach 1:
The breeding program segments the trait integration process into distinct phases: initial genetic transformation to introduce specific traits, followed by traditional breeding steps including backcrossing, selection, and stabilization. This segmentation allows complex multi-trait varieties to be developed through manageable, sequential steps rather than attempting to combine all traits simultaneously.
Solution Approach 2:
The program performs preliminary genetic transformation to introduce desired traits before undertaking extensive traditional breeding operations. By pre-introducing traits through transformation, the subsequent breeding steps focus on stabilization and optimization rather than simultaneous trait introduction, reducing overall program complexity.
3Adaptability or versatility
If transgenic genes are introduced through genetic transformation, then new traits such as herbicide resistance are conferred, but the morphological characteristics may be altered
Solution Approach 1:
The breeding program applies local quality by focusing genetic transformation on specific traits (such as herbicide resistance or disease resistance) while maintaining the overall morphological characteristics of the wheat cultivar. This targeted approach introduces novel functions without fundamentally altering the plant's fundamental structure and physiology.
Solution Approach 2:
The program carefully controls the parameters of genetic transformation to minimize unintended effects on morphological characteristics. By optimizing transformation conditions and selecting for specific phenotypes in subsequent generations, the program achieves desired trait integration while maintaining stability in morphological and physiological properties.
