Pepper Hybrid PS 16375253 Segmentation for Uniform Disease Resistance
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 PS 16375253 and inbred lines SBR-163-5054 and SLY-163-5055, which incorporate specific genetic loci conferring herbicide tolerance, insect resistance, disease resistance, and modified carbohydrate metabolism through natural or induced mutations, or genetic transformation, ensuring a uniform and stable population.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pedigree breeding and recurrent selection methods are used to develop inbred plants, then genetic diversity is increased through combining backgrounds from multiple plants, but the resulting hybrid plants show genetic non-uniformity leading to unpredictable performance
Solution Approach 1:
The patent segments the breeding process into distinct phases: developing homozygous inbred lines through self-pollination, then crossing these fixed lines to produce uniform F1 hybrids. This segmentation separates genetic diversity generation (in the breeding pools) from performance uniformity (in the commercial hybrids), resolving the contradiction between adaptability and reliability.
Solution Approach 2:
The patent changes the genetic uniformity parameter by using multiple generations of self-pollination to fix alleles in parent lines, then exploiting heterosis in the F1 generation. This parameter change from homozygous parents to heterozygous hybrids achieves both genetic diversity (through broad breeding pools) and performance predictability (through uniform F1 hybrids).
2Stability of the object's composition
If self-pollination is used to develop homozygous inbred plants, then uniform true-breeding progeny is achieved, but genetic diversity is reduced
Solution Approach 1:
The patent applies preliminary action by developing homozygous inbred lines through extended self-pollination before the crossing stage. This preliminary fixation of genetics in parent lines ensures that subsequent F1 hybrids will be uniform, while the broadening of breeding pools before this point maintains genetic diversity for selection.
3Adaptability or versatility
If cross-pollination between different plant varieties is used, then genetic diversity and desirable traits are combined, but the resulting hybrid population becomes genetically non-uniform
Solution Approach 1:
The patent segments the cross-pollination process into controlled crosses between fixed inbred lines rather than open pollination. This segmentation ensures that while genetic diversity is combined from different parent lines, the F1 hybrid population remains genetically uniform because both parents are homozygous and genetically fixed.
