Inbred Corn Line RQQ071 for Predictable Hybrid Trait Expression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn breeding technologies face challenges in developing high-yielding, agronomically sound hybrids with desirable traits such as resistance to diseases and insects, tolerance to environmental stresses, and uniformity, which are unpredictable and resource-intensive due to the complexity of genotype interactions with environmental conditions.
Innovation Solution
The development of a novel inbred corn line, RQQ071, with specific genetic traits and breeding methods like backcross conversion, genetic engineering, and transformation to introduce desired traits like disease resistance and uniformity, along with processes for creating hybrids and modified plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional corn breeding methods are used to develop hybrids with desirable traits, then various traits such as disease resistance and yield can be combined, but the process becomes unpredictable and resource-intensive due to genotype-environment interaction complexity
Solution Approach 1:
The patent segments the complex breeding process by developing distinct inbred lines (such as RQQ071 and its parental lines) with specific standardized traits, then combining them through controlled crosses. This breaks down the unpredictable whole-process breeding into manageable, reproducible components with defined genetic contributions.
Solution Approach 2:
The patent applies parameter changes by modifying specific genetic parameters through inbreeding and selection to create lines with standardized characteristics (e.g., uniform maturity, specific plant height, consistent kernel traits). This standardization reduces the variability caused by genotype-environment interactions.
2Adaptability or versatility
If multiple desirable traits are combined in a single corn variety, then resistance to diseases and insects, tolerance to environmental stresses, and yield can be improved, but the breeding process becomes more complex and resource-intensive
Solution Approach 1:
The patent segments trait incorporation by developing specialized inbred lines that each contribute specific traits (e.g., disease resistance, uniformity, yield potential). Line RQQ071 and its parents represent segmented genetic contributions that are combined through controlled crossing, making the complex multi-trait breeding process more manageable.
Solution Approach 2:
The patent merges multiple desirable traits by crossing complementary inbred lines. The hybrid combines traits from both parents, achieving disease resistance, environmental stress tolerance, and high yield potential simultaneously through the synergistic combination of standardized parental lines.
3Manufacturing precision
If uniformity of plant characteristics is achieved for mechanical harvesting, then harvest efficiency and processing quality improve, but genetic diversity and adaptability may be reduced
Solution Approach 1:
The patent applies parameter changes by standardizing specific genetic parameters (maturity timing, plant height, ear position, kernel traits) through inbreeding and selection. This creates uniformity in critical harvesting-related characteristics while maintaining the ability to adapt through controlled crossing with lines possessing different standardized traits.
