Maize Inbred PH13KD Uniformity and Stress Resistance
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, PH13KD, with specific genetic traits introduced through backcross conversion and transformation, focusing on improved resistance to abiotic stress, diseases, and mechanical stability, along with processes for producing hybrid seeds and plants that incorporate these traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding is used to combine desirable traits, then resistance to diseases and insects, resistance to heat and drought, reducing the time to crop maturity, greater yield, and better agronomic quality can be achieved, but uniformity of plant characteristics such as germination, stand establishment, growth rate, maturity, plant height and ear height is compromised
Solution Approach 1:
The patent segments the plant breeding process into distinct stages: creating inbred lines with uniformity, then combining them in controlled crosses to produce hybrids with desired traits. This segmentation allows each stage to be optimized independently - inbreeding for uniformity and crossing for trait combination.
Solution Approach 2:
The patent merges the benefits of inbred lines (uniformity) with the advantages of hybrid crosses (trait combination) to create a solution where both uniformity and desirable traits are achieved simultaneously in the final hybrid variety.
2Productivity
If mechanical harvesting is implemented, then crop production efficiency is improved, but uniformity of plant characteristics such as plant height and ear height becomes critical
Solution Approach 1:
The patent applies local quality by ensuring uniformity of critical mechanical harvesting characteristics (plant height, ear height) while allowing variation in other traits. The inbred lines are specifically selected and bred for uniformity in dimensions that affect mechanical harvesting performance.
3Reliability
If backcross conversion and transformation are used to introduce specific traits, then resistance to abiotic stress and diseases is improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent performs preliminary actions by creating inbred lines with uniformity and stability before conducting the final crosses. This preliminary inbreeding process establishes a stable genetic foundation that simplifies subsequent trait introduction through backcross conversion and transformation.
