Pepper Hybrid PS09954859 Uniformity via Segmented Inbred Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plant breeding methods face challenges in developing uniform pepper varieties with desirable traits such as resistance to diseases and environmental stress, as they often result in unpredictable performance due to genetic non-uniformity in hybrid plants.
Innovation Solution
The development of pepper hybrid PS09954859 and inbred lines SMR 99-1275 and SMY 99-1322, which are homozygous and uniform, incorporating traits like herbicide tolerance, insect resistance, and disease resistance through genetic loci modifications, including natural genes, mutations, or transgenes, to produce stable and uniform seed populations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination between different plant varieties is used to create hybrid plants, then genetic diversity and adaptability are improved, but uniformity and predictability of performance deteriorate
Solution Approach 1:
The patent applies segmentation by developing separate inbred lines (SMR 99-1275 and SMY 99-1322) that are genetically uniform and true-breeding, then combining them through controlled cross-pollination to produce uniform F1 hybrids. This segmentation allows each parent line to be optimized for specific traits while ensuring predictable hybrid performance.
Solution Approach 2:
The patent changes the genetic parameters by creating homozygous inbred lines through multiple generations of self-pollination and selection, then using these standardized genetic parameters to produce uniform F1 hybrids with consistent and predictable performance characteristics.
2Reliability
If self-pollination and selection over many generations are used to create homozygous plants, then uniformity and true-breeding characteristics are improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by developing and characterizing two distinct inbred lines (SMR 99-1275 and SMY 99-1322) before creating the F1 hybrid. These pre-characterized lines serve as standardized parents that can be quickly crossed to produce uniform hybrids, reducing the overall breeding time compared to developing uniformity from scratch.
3Adaptability or versatility
If broad-based breeding pools are used to combine genetic backgrounds, then adaptability and trait diversity are improved, but uniformity and consistency of hybrids deteriorate
Solution Approach 1:
The patent applies local quality by creating inbred lines with specific, well-defined genetic characteristics (SMR 99-1275 with certain traits and SMY 99-1322 with other traits), then combining these localized genetic improvements through controlled crossing to produce uniform F1 hybrids with consistent and predictable characteristics.
