Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheat breeding methods face challenges in combining desirable traits such as high seed yield, disease resistance, drought tolerance, and improved agronomic characteristics into a single wheat variety, while maintaining uniformity and stability.
Innovation Solution
The development of the wheat variety W060036K1, which involves genetic modification and locus conversion through transgenic techniques, including the introduction of specific genes for traits like herbicide resistance, disease resistance, and abiotic stress tolerance, combined with traditional breeding methods like backcrossing and selection to achieve desired phenotypic and morphological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to combine multiple desirable traits, then the complexity of the breeding process increases, but the uniformity and stability of the resulting variety may be compromised
Solution Approach 1:
The patent segments the breeding process into distinct stages: initial cross-breeding to introduce desired traits, followed by backcrossing to recover the recurrent parent genome, and final selection to fix the target traits. This segmentation allows systematic combination of multiple traits while maintaining process control and reducing overall complexity.
Solution Approach 2:
The patent employs preliminary action through pre-planned breeding schemes where the recurrent parent is selected beforehand for its superior agronomic characteristics, and the breeding strategy (number of backcrosses, selection criteria) is predetermined. This preliminary planning reduces complexity during execution by providing a clear roadmap for trait combination.
2Manufacturing precision
If multiple generations of backcrossing are performed to introgress desired traits, then the purity of the recurrent parent genome increases, but the time required for variety development increases
Solution Approach 1:
The patent applies parameter changes by adjusting the number of backcrossing generations based on the specific breeding goals and the genetic distance between parents. Instead of fixing the number of backcrosses, the methodology allows flexibility in this parameter to balance genome purity requirements against time constraints, optimizing the breeding process for different scenarios.
Solution Approach 2:
The patent incorporates feedback mechanisms through molecular marker-assisted selection during backcrossing, where DNA markers linked to desired traits are monitored to guide selection decisions. This feedback allows breeders to make informed decisions about when sufficient purity has been achieved, avoiding unnecessary additional backcrossing generations and reducing development time.
3Stability of the object's composition
If selective breeding is applied to fix desirable traits, then the uniformity of the variety improves, but the genetic diversity may be reduced
Solution Approach 1:
The patent applies local quality by focusing selection pressure specifically on the regions of the genome containing the desired traits while allowing the rest of the genome to maintain the diversity of the recurrent parent. This localized approach ensures uniformity for the target traits without unnecessarily reducing overall genetic diversity in the variety.
Solution Approach 2:
The patent uses molecular markers that can simultaneously track multiple traits and genomic regions during the breeding process. This multi-functional tool allows breeders to monitor both the fixation of desired traits and the maintenance of genetic diversity in other regions, achieving uniformity where needed while preserving diversity elsewhere.
