Maize Inbred PH1V5T Homogeneity for Uniform Harvesting
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 mechanical harvesting.
Innovation Solution
Development of the novel maize variety PH1V5T, which is a homozygous inbred line with improved traits like resistance to diseases, insects, heat, and drought, and its use in breeding processes to create hybrid seeds with enhanced agronomic qualities through crossing and locus conversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding is used to combine desirable traits, then disease resistance and drought tolerance can be improved, but the time required to develop new varieties increases and uniformity of plant characteristics deteriorates
Solution Approach 1:
The patent applies preliminary action by developing and maintaining a pre-characterized inbred maize line (PH1V5T) with known desirable traits including disease resistance, drought tolerance, and uniformity. This pre-developed inbred line serves as a ready-to-use genetic foundation that eliminates the need for time-consuming traditional breeding to combine these traits, allowing breeders to immediately utilize these traits in hybrid development without undergoing lengthy selection and stabilization processes.
2Reliability
If traditional plant breeding is used to combine desirable traits, then drought tolerance can be improved, but uniformity of plant characteristics deteriorates
Solution Approach 1:
The patent applies homogeneity by developing PH1V5T as a highly homozygous inbred maize line through extended selfing and selection. This homozygosity ensures uniform expression of desirable traits including drought tolerance across all plants in the population. The inbred line exhibits consistent plant characteristics such as uniform germination, stand establishment, growth rate, maturity, plant height, and ear height, providing the uniformity required for mechanical harvesting while maintaining improved drought tolerance.
3Productivity
If traditional plant breeding is used to improve yield, then productivity can be increased, but the complexity of the breeding process increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding process into distinct, manageable components: (1) development of the PH1V5T inbred line with specific desirable traits, (2) characterization of its genetic and phenotypic properties, and (3) use as a parental line in hybrid development. This segmentation simplifies the overall breeding process by providing a ready-made, well-characterized genetic foundation that breeders can systematically combine with other inbred lines to produce hybrids with improved yield, eliminating the need to simultaneously manage multiple complex breeding operations.
