Find Innovative SolutionsGenerate Solutions
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 PHWNY, which involves crossing with other maize plants to introduce desired traits through backcross conversion and transformation, resulting in a hybrid with enhanced 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 proceed with conventional techniques, but the ability to efficiently combine multiple 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 detect and select specific genetic traits at the DNA level, transforming the breeding process from phenotypic selection to genotypic selection. This enables simultaneous tracking and combination of multiple desirable traits (disease resistance, drought tolerance, uniformity) through marker-assisted selection, significantly improving breeding efficiency and the ability to combine multiple traits in a single variety
2Productivity
If mechanical harvesting is implemented, then crop production efficiency is improved, but uniformity of plant characteristics such as germination, stand establishment, growth rate, maturity, plant height and ear height becomes critically important and harder to achieve
Solution Approach 1:
The patent applies preliminary action by using molecular markers to identify and select plants with desired uniformity traits before actual planting and growth. By detecting genetic markers associated with uniform germination, stand establishment, growth rate, maturity, plant height, and ear height at the seedling or early growth stage, breeders can pre-select uniform plants for mechanical harvesting, ensuring the required uniformity is established before the harvesting process begins
Solution Approach 2:
The patent replaces traditional mechanical/visual selection methods with molecular marker-based genetic detection. Instead of manually selecting plants based on observable characteristics, the invention uses DNA marker technology to identify and select plants with genetic markers for uniformity traits, providing more precise and reliable selection for mechanical harvesting compatibility
3Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the overall performance and yield are improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent applies feedback through marker-assisted selection, where molecular markers provide real-time genetic information about the presence of desired traits during the breeding process. This feedback mechanism allows breeders to track multiple traits simultaneously, make informed selection decisions, and adjust breeding strategies based on genetic data, thereby managing the complexity of combining multiple traits while improving overall variety performance
