Genomic Selection for Crop Improvement
JMP Genomics serves as your experimental design and analysis platform for crop-breeding programs. Biologists and breeders can employ linkage mapping and QTL analysis for experimental populations, and complex association methods for diversity populations to identify markers for pest and pathogen resistance.
Comprehensive predictive modeling reviews perform genomic selection with multiple traits of interest to improve breeding selection and accuracy, allowing insights that aren’t possible with classical phenotypic selection. These genomic selection tools uncover optimal combinations of markers to produce desirable traits, which in turn can be used to design and evaluate future crosses to produce healthier foods.
- Perform molecular marker-assisted selection to improve crop viability and performance.
- Utilize multi-trait predictive modeling reviews to optimize breeding programs.
- Evaluate potential crosses and simulate their progeny based on genomic selection model scoring to determine optimal breeding strategies for future performance.
JMP Genomics allows you to import variant data sets from VCF files, CLCbio SNP and indel reports, summary files from Complete Genomics, Plink text and binary files, and common output formats from SNP arrays. Once imported, choose from extensive association analysis options from simple case-control association to complex linear models supporting covariates, interactions and random effects.
Select from an extensive set of rare variant association methods to group rare SNP variants within genes, pathways or positional groups, or identify genomic regions shared identical by state (IBS) between related or unrelated individuals. You can also analyze patterns of linkage disequilibrium, correct for population structure and discover SNP-SNP interactions. Create, compress and easily integrate relationship matrices into association tests to simultaneously correct for population structure and relatedness with Q-K mixed model analysis.
With support for intensity, aligned read, and count data formats, JMP Genomics lets biologists and biostatisticians normalize and analyze both array data and summaries from next-gen studies, providing several scaling and normalization methods tailored for count data sets.
