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, PH1DN2, with specific genetic traits introduced through backcross conversion and transformation, enhancing resistance to various stresses and improving agronomic qualities like yield and maturity.
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, 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 applies parameter changes by utilizing molecular markers and genomic selection to precisely control and optimize plant characteristics. Through changes in breeding parameters and selection criteria, the invention achieves both improved resistance traits and uniformity in plant characteristics, resolving the contradiction between reliability and stability.
2Productivity
If mechanical harvesting is implemented, then crop production efficiency is improved, but uniformity of plant characteristics such as maturity, plant height and ear height becomes critical
Solution Approach 1:
The patent employs feedback mechanisms through molecular marker-assisted selection and genomic evaluation to continuously monitor and adjust plant characteristics. This feedback loop ensures that uniformity in maturity, plant height, and ear height is maintained while achieving high crop production efficiency for mechanical harvesting.
3Reliability
If backcross conversion and transformation are used to introduce desirable traits, then resistance to stresses and agronomic qualities are improved, but breeding complexity increases
Solution Approach 1:
The patent uses molecular markers and genomic tools as intermediaries to simplify the backcross conversion and transformation processes. These intermediaries enable precise tracking and selection of desired traits, reducing the complexity of breeding operations while achieving improved stress resistance and agronomic qualities.
