1PDSF05 Maize Inbred Line for Faster Multi-Trait Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties is a time-consuming process that requires years to combine desirable traits such as disease resistance, drought tolerance, and high yield, posing challenges in efficiently producing stable and agronomically sound maize varieties.
Innovation Solution
The development of a novel maize variety, 1 PDSF05, which incorporates specific traits like male sterility, disease resistance, and drought tolerance through genetic manipulation and transformation, along with processes for producing hybrid seeds and plants, including methods to prevent self-pollination and enhance cross-pollination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize variety development processes are used to combine desirable traits, then the maize varieties achieve stable and agronomically sound characteristics, but the development process takes six to twelve years which is time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing inbred lines with specific desirable traits (disease resistance, drought tolerance, yield potential) before combining them. The inbred lines are prepared and tested in advance, allowing the breeding process to start from a pre-qualified pool rather than developing traits from scratch, thus reducing the overall development time while maintaining variety stability
2Adaptability or versatility
If multiple desirable traits are combined in a single maize variety through breeding, then the variety achieves greater yield and stress tolerance, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent segments the complex breeding process into distinct phases: first developing individual inbred lines with specific traits (disease resistance, drought tolerance), then combining these pre-developed lines through controlled crossing. This segmentation allows each trait to be optimized independently in separate inbred lines before combination, reducing the overall complexity compared to attempting to develop all traits simultaneously in a single breeding program
Solution Approach 2:
The patent uses inbred lines as intermediary carriers for desirable traits. Each inbred line serves as an intermediary that holds and transmits specific trait combinations (e.g., one inbred line carries disease resistance, another carries drought tolerance). These intermediaries facilitate the systematic combination of multiple traits through controlled crosses, making the breeding process more manageable and less complex
