Solution Overview
Problem
Current maize breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and uniformity, which are essential for efficient crop production and yield improvement.
Innovation Solution
Development of the maize variety PH10MS, which is a novel inbred line with specific traits introgressed through backcross conversion and transformation, combined with processes for making PH10MS seeds and plants, and hybrid seeds produced by crossing PH10MS with other maize varieties, incorporating genetic material for improved resistance and agronomic qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding methods are used to combine desirable traits, then the breeding process can be completed using conventional techniques, but the ability to effectively combine multiple desirable traits such as disease resistance, drought tolerance, and uniformity is limited
Solution Approach 1:
The patent applies parameter changes by utilizing molecular marker technology to transform the breeding process from phenotypic selection to genotypic selection. This changes the fundamental parameter of trait assessment from observable characteristics to genetic markers, enabling simultaneous tracking and combination of multiple desirable traits (disease resistance, drought tolerance, uniformity) with greater precision and efficiency than traditional methods
Solution Approach 2:
The patent replaces the mechanical/physical selection process of traditional breeding with molecular-based selection. Instead of visually assessing and selecting plants based on phenotypic traits, the invention uses DNA marker analysis to identify and select plants carrying desired genetic markers, substituting the mechanical selection process with a molecular-level approach that enables more effective combination of multiple traits
2Productivity
If traditional breeding methods are used, then the process is simpler and requires less advanced technology, but the yield improvement and trait combination capability are insufficient
Solution Approach 1:
The patent introduces molecular markers as an intermediary between the breeder and the target traits. These markers serve as proxies or indicators that allow selection for complex traits (disease resistance, drought tolerance, uniformity) without directly observing or measuring the traits themselves. This intermediary approach enables more accurate and efficient trait combination, leading to improved yield while managing the complexity through a systematic marker-assisted selection framework
3Stability of the object's composition
If conventional breeding techniques are used to achieve uniformity, then the breeding process remains traditional and accessible, but the uniformity of plant characteristics such as germination, stand establishment, growth rate, maturity, plant height and ear height is insufficient
Solution Approach 1:
The patent applies preliminary action by performing molecular marker analysis during early breeding stages to identify and select plants with desired genetic characteristics before phenotypic expression occurs. This advance selection based on genetic markers ensures that uniformity in plant characteristics (germination, stand establishment, growth rate, maturity, plant height, ear height) is established at the genetic level, leading to more uniform and productive crops while reducing the need for later selection and re-breeding
