Maize Inbred PH1TRG Breeding for Disease Resistance and Yield
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 mechanical harvesting.
Innovation Solution
Development of a novel maize variety, PH1TRG, with specific breeding processes and genetic modifications to introduce desired traits through backcross conversion and transformation, enhancing resistance to various stresses and improving agronomic qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding methods are used to combine desirable traits, then disease resistance and drought tolerance can be improved, but the time required to develop new varieties and the complexity of the breeding process increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-characterizing the PH1TRG inbred line with multiple desirable traits (disease resistance, drought tolerance, uniformity) before hybridization. This allows breeders to start with a pre-optimized parent that already possesses resistance to multiple diseases (gray leaf spot, northern leaf blight, common rust) and abiotic stresses, reducing the time needed for subsequent trait combination compared to traditional step-by-step breeding
2Productivity
If multiple desirable traits are combined in a single variety, then agronomic quality and yield potential improve, but the complexity of the breeding process and difficulty of achieving uniformity increase
Solution Approach 1:
The patent merges multiple desirable traits into the PH1TRG inbred line through systematic breeding, combining resistance to multiple diseases (gray leaf spot, northern leaf blight, common rust, anthracnose stalk rot) and tolerance to abiotic stresses (drought, heat) along with uniform plant characteristics. This consolidated inbred line then serves as a parent for hybrids, simplifying the overall breeding process by consolidating multiple trait integration steps into one pre-developed parent
3Ease of operation
If uniformity of plant characteristics is improved for mechanical harvesting, then ease of operation and harvesting efficiency improve, but the adaptability to different environmental conditions may be reduced
Solution Approach 1:
The patent applies parameter changes by modifying the PH1TRG inbred line to exhibit uniform key parameters (plant height, ear height, maturity timing, growth rate) that are critical for mechanical harvesting while simultaneously maintaining or enhancing adaptability parameters through incorporated resistance traits. The uniformity in structural parameters enables efficient mechanical harvesting, while the genetic diversity in stress resistance traits preserves environmental adaptability
