Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheat cultivars lack improved combinations of desirable traits such as higher seed yield, disease resistance, insect resistance, drought tolerance, 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 01095270, which is a HARD RED WINTER type common wheat, bred for winter regions in the US, incorporating traits like improved seed yield, disease resistance, and herbicide tolerance through genetic transformation and traditional breeding techniques, along with the use of transgenic genes for specific traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding techniques are used to combine desirable traits, then genetic diversity and trait combination potential are improved, but the time required to develop new cultivars and the complexity of the breeding program increase
Solution Approach 1:
The patent applies preliminary action by pre-screening and selecting parental lines with specific desirable traits (disease resistance, yield potential, agronomic quality) before initiating the breeding program. This advance preparation of germplasm with known trait profiles accelerates the subsequent breeding process by reducing the need for extensive screening in later generations.
Solution Approach 2:
The patent uses molecular markers as intermediaries to track and select for desirable traits during the breeding process. These markers serve as proxies for complex trait combinations, allowing breeders to efficiently select plants carrying multiple desired traits without having to wait for phenotypic expression in each generation, thus reducing development time.
2Productivity
If multiple desirable traits are combined in a single cultivar, then productivity and versatility are improved, but the genetic complexity and difficulty of breeding increase
Solution Approach 1:
The patent applies local quality by focusing on combining specific, locally-important traits (such as resistance to particular diseases prevalent in the region, or traits suited to local growing conditions) rather than attempting to combine all possible desirable traits. This targeted approach to trait combination reduces genetic complexity while maintaining high productivity for the specific target environment and use case.
3Reliability
If disease resistance and insect resistance are incorporated into the cultivar, then reliability and crop protection are improved, but the genetic complexity and breeding difficulty increase
Solution Approach 1:
The patent employs molecular markers as intermediaries to track disease resistance genes through the breeding process. By using DNA markers linked to resistance genes, breeders can reliably select for disease resistance at the seedling stage without needing to expose plants to disease pressure or wait for symptom development, thereby simplifying the breeding process while maintaining high reliability of resistance trait incorporation.
