Maize Hybrid X13P503 Trait Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional plant breeding methods face challenges in simultaneously achieving desirable traits such as disease resistance, drought tolerance, and uniformity in crop characteristics, particularly in maize, which are essential for mechanical harvesting and high yield.
Innovation Solution
The development of a novel maize hybrid variety, X13P503, achieved through crossing two inbred varieties and introducing specific genetic loci via locus conversion, backcrossing, and transformation, incorporating traits like male sterility, insect resistance, and disease resistance, while maintaining uniform physiological and morphological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding methods are used to combine desirable traits, then disease resistance and insect resistance can be achieved, but uniformity of plant characteristics and yield are compromised
Solution Approach 1:
The patent segments the breeding process into distinct stages: first developing inbred lines with specific resistance traits, then crossing them to create hybrids. This segmentation allows each parent line to contribute specific desirable traits (disease resistance, insect resistance) while the hybrid combination achieves uniformity and high yield, resolving the contradiction between trait incorporation and productivity.
2Reliability
If traditional plant breeding methods are used to achieve multiple desirable traits, then disease resistance and drought tolerance can be incorporated, but uniformity of plant characteristics is reduced
Solution Approach 1:
The patent merges multiple desirable traits (disease resistance, drought tolerance, uniformity) into a single hybrid variety through controlled crossing of inbred lines. Each inbred line is developed to be genetically uniform, and their hybrid combination maintains this uniformity while incorporating multiple resistance traits, thus combining reliability under stress with stability of plant characteristics.
3Adaptability or versatility
If traditional plant breeding methods are used to develop new varieties, then various desirable traits can be combined, but the time to achieve maturity and uniform stand establishment is increased
Solution Approach 1:
The patent applies preliminary action by first developing and stabilizing inbred lines with specific desirable traits before combining them into hybrids. This preliminary development ensures that when the hybrid is created, it immediately exhibits the desired trait combinations without requiring additional breeding generations, thus reducing the time to achieve maturity while maintaining adaptability through trait combination.
