Maize Inbred ID6461 Transgenic Traits for Hybrid Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corn breeding faces challenges in producing high-yielding, agronomically sound plants that are uniformly adapted across the U.S. Corn Belt, as regional growing conditions and specific issues like Gray Leaf Spot infection, cool temperatures, and soil pH levels require tailored traits in hybrids, which are often not uniformly adapted.
Innovation Solution
The development of the maize variety ID6461, which includes specific traits such as increased water stress resistance, waxy starch, male sterility, and disease resistance, conferred by transgenes, and the use of advanced breeding methods like backcrossing and marker-assisted selection to introduce desired traits into the inbred line, ensuring adaptability and high performance across different regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If inbred maize lines are used for hybrid seed production, then uniformity and reproducibility of hybrid seed are improved, but seed production efficiency deteriorates due to decreased vigor
Solution Approach 1:
The patent applies local quality by introducing specific transgenes into the inbred line ID6461 that confer localized stress resistance traits (disease resistance, water stress resistance) without affecting the overall homozygosity and uniformity of the line. This allows the inbred to maintain its uniformity while gaining specific adaptive qualities that improve vigor and seed production efficiency.
2Adaptability or versatility
If regional adaptation is improved by tailoring hybrids to specific regions, then performance in specific regions is improved, but uniform adaptability across the Corn Belt deteriorates
Solution Approach 1:
The patent applies universality by developing inbred line ID6461 with multiple stress resistance traits (disease resistance, water stress resistance, Gray Leaf Spot resistance) that function across diverse environmental conditions. This multi-functional inbred can be used to produce hybrids adapted to various Corn Belt regions while maintaining consistent performance characteristics across different locations.
Solution Approach 2:
The patent applies composite materials by creating an inbred line that combines multiple resistance traits (disease resistance genes, stress resistance genes) into a single genetic background. This composite genetic structure provides broad-spectrum adaptability across different regions while maintaining uniformity in the base characteristics of the inbred line.
3Reliability
If multiple stress resistance traits are introduced into inbred line ID6461, then resistance to various stresses and diseases is improved, but genetic complexity increases
Solution Approach 1:
The patent applies merging by combining multiple resistance traits (disease resistance, water stress resistance, Gray Leaf Spot resistance) into a single integrated inbred line ID6461. This consolidation of multiple protective functions into one genetic background provides comprehensive reliability while managing genetic complexity through systematic breeding approaches.
