Maize Inbred PH1D0D 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 yield improvement.
Innovation Solution
Development of a novel maize variety, PH1D0D, through specific breeding methods and genetic marker profiles, which can be used to produce hybrid seeds and plants with enhanced traits by crossing with other maize varieties, and introducing desired traits through backcross conversion and transformation.
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 achieved, but the time required for breeding and the complexity of the process increase
Solution Approach 1:
The patent develops inbred line PH1D0D with pre-established desirable traits including disease resistance and uniformity through traditional breeding. This pre-developed inbred line serves as a ready-to-use parental line that eliminates the need for time-consuming trait combination in subsequent hybrid development, allowing breeders to directly cross PH1D0D with other inbreds to produce hybrids with known desirable characteristics.
2Stability of the object's composition
If traditional plant breeding is used to achieve uniformity in plant characteristics, then mechanical harvesting compatibility is improved, but the breeding complexity and difficulty of achieving consistent uniformity increase
Solution Approach 1:
The patent develops inbred line PH1D0D with highly uniform plant characteristics including consistent germination, stand establishment, growth rate, maturity, plant height, and ear height. This homogeneity in the inbred line ensures that all hybrids produced from PH1D0D will exhibit uniformity, making them compatible with mechanical harvesting without requiring complex breeding interventions to achieve consistency.
3Productivity
If multiple desirable traits are combined in a single variety, then agronomic quality and yield are improved, but the difficulty of detecting and measuring all traits simultaneously increases
Solution Approach 1:
The patent segments the breeding process into distinct components: developing inbred line PH1D0D with specific desirable traits (disease resistance, uniformity, drought tolerance), and then crossing it with other inbred lines that contribute additional traits. This segmentation allows for systematic evaluation of individual parent lines for specific traits, making the overall trait detection and measurement process more manageable compared to attempting to evaluate all traits simultaneously in a single multi-trait breeding program.
