LLM12BM Inbred Corn Line Yield and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new inbred corn lines is a slow and costly process, requiring expertise and numerous steps, and existing inbred parent corn lines lose commercial competitiveness over time, necessitating the need for improved germplasm with enhanced yield, disease resistance, and trait technologies.
Innovation Solution
The introduction of the inbred corn line LLM12BM, which is a yellow dent inbred corn line with specific physiological and morphological characteristics, and methods for producing and utilizing it, including self-pollination, sib-pollination, and hybrid production, along with genetic modification and treatment with agricultural chemicals to enhance resistance to stress conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional inbreeding techniques are used to develop new inbred corn lines, then genetic uniformity and homozygosity are improved, but the process is slow and costly, and commercial competitiveness is lost over time
Solution Approach 1:
The patent applies preliminary action by pre-selecting and pre-characterizing inbred lines with desirable traits before they are fully developed or commercialized. The inbred line LLM12BM was developed with specific traits (drought resistance, disease resistance, uniformity) established in advance through multiple generations of self-pollination and selection, allowing it to be immediately competitive when introduced to the market without requiring further breeding time.
2Reliability
If existing inbred parent corn lines are used, then current varieties are maintained, but they lose commercial competitiveness over time due to declining yield and disease resistance
Solution Approach 1:
The patent applies parameter changes by modifying and enhancing specific traits of the inbred line through controlled breeding and selection. LLM12BM exhibits improved parameters compared to existing lines, including increased yield potential, enhanced disease resistance, and superior uniformity. These parameter improvements are achieved through systematic selection and crossing programs that optimize each trait individually and then combine them.
3Object-affected harmful factors
If protective chemicals are applied to corn plants, then disease and stress resistance is improved, but production costs increase
Solution Approach 1:
The patent applies self-service by developing inbred lines that possess inherent resistance to diseases and stress conditions through their genetic composition. LLM12BM is designed to be self-protecting against common corn diseases and environmental stresses, reducing or eliminating the need for external protective chemicals. This self-service approach allows the plant to defend itself using its own genetic traits rather than relying on external chemical interventions.
