Maize Inbred 1PRMP07 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, 1PRMP07, which incorporates specific traits through backcross conversion, genetic manipulation, and transformation, including cytoplasmic male sterility and heritable traits like herbicide tolerance and disease resistance, facilitated by processes such as crossing and tissue culture to produce homogeneous inbred seeds and hybrid seeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize variety development processes are used to combine desirable traits, then stable and high-yielding maize varieties are achieved, but the development time becomes excessively long (6-12 years)
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 line 1PRMP07 was developed with predetermined characteristics including resistance to northern corn leaf blight, gray leaf spot, and common rust, allowing for more efficient hybrid development without the full 6-12 year traditional timeline.
2Adaptability or versatility
If multiple desirable traits are combined in a single maize variety, then agronomic performance and yield are improved, but the breeding process complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct stages: developing parent inbred lines with specific traits (1PRMP07 with disease resistance, another parent with yield traits), then combining them in hybridization. This segmented approach allows each parent to be optimized for specific functions, reducing overall breeding complexity while achieving multi-trait hybrids with superior agronomic performance.
