Maize Inbred 1PLRC84 Accelerating Hybrid Development
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process, typically taking six to twelve years from the initial cross to the delivery of finished seed to farmers, due to the complexity of combining desirable traits such as disease resistance, drought tolerance, and high yield.
Innovation Solution
The introduction of the novel maize variety 1PLRC84, which can be crossed with other maize plants to produce hybrid seeds, and the use of genetic manipulation and transformation techniques to introgress desired traits into the variety, thereby accelerating the breeding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding methods are used to combine desirable traits, then stable high-yielding varieties are developed, but the process takes six to twelve years
Solution Approach 1:
The patent applies preliminary action by pre-characterizing the inbred maize line 1PLRC84 with multiple desirable traits (disease resistance, abiotic stress tolerance, yield potential) before hybridization. This preliminary preparation allows breeders to start with a genetically optimized base, reducing the time needed for subsequent trait combination and variety stabilization while maintaining reliability
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then agronomic performance is improved, but the breeding process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the complex trait combination process into manageable components: (1) developing a pre-characterized inbred base line with core traits, (2) selecting complementary inbred lines with additional desirable traits, and (3) creating hybrids that combine these segmented trait sets. This segmentation reduces breeding process complexity while achieving comprehensive agronomic performance
3Productivity
If the inbred line has high general combining ability, then hybrid performance is improved, but selection and testing require more time
Solution Approach 1:
The patent applies preliminary action by pre-evaluating and characterizing inbred line 1PLRC84 for high general combining ability across multiple traits before hybridization programs begin. This preliminary characterization includes assessing disease resistance, stress tolerance, and yield potential in advance, allowing rapid identification of superior hybrid combinations without extensive subsequent testing, thus improving hybrid productivity while reducing selection time
