Maize Variety PHRAN Trait Introgression and Hybrid Development
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, PHRAN, which combines desirable traits through crossing, backcross conversion, and transformation processes, allowing for the introgression of specific traits and the creation of hybrid maize seeds and plants with enhanced agronomic characteristics.
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 process is time-consuming and yields are limited
Solution Approach 1:
The patent employs preliminary action by pre-selecting and characterizing inbred lines with specific desirable traits (disease resistance, drought tolerance, uniformity) before combining them in hybrid development. This preparatory work accelerates the breeding process by having ready-to-use parental lines with known characteristics, reducing the time needed for trait combination and evaluation.
2Reliability
If traditional plant breeding methods are used to combine desirable traits, then disease resistance and drought tolerance can be achieved, but yield improvement is limited
Solution Approach 1:
The patent applies merging by combining multiple inbred lines with complementary traits into hybrid varieties. This integration of diverse genetic material allows the hybrid to simultaneously express disease resistance, drought tolerance, and high yield potential, achieving multiple objectives that traditional single-trait breeding could not accomplish.
3Productivity
If mechanical harvesting is used, then harvesting efficiency is improved, but uniformity of plant characteristics becomes critical and difficult to achieve
Solution Approach 1:
The patent applies local quality by selecting and emphasizing specific uniformity traits (germination, stand establishment, growth rate, maturity, plant height, ear height) in the hybrid development process. This targeted approach to uniformity ensures that critical plant characteristics are consistent enough to support efficient mechanical harvesting while maintaining the high yield potential required for productivity.
