Status of Computational Approaches for Polyploid Crops (2018)

TetraploidSNPMap: Software for Analyzing Autotetraploid Mapping Population 

This presentation discusses their aim to develop the theory and software for constructing linkage maps and mapping QTLs in biparental populations of autoploid species. It is motivated by the James Hutton Institute research on potatoes in collaboration with Glenn Bryan and colleagues.

A Genetic Analysis Pipeline for Polyploids 

This presentation describes the polyploid projects of 12 different breeding companies working together for the goals of developing genetic analysis pipelines for polyploids with an emphasis on methods and tools.

GWAS and Genomic Selection (GS) for Polyploid Crops

This presentation discusses the linkage vs. linkage disequilibrium (LD), how GWAS=LD mapping works, the kinship matrix from both pedigree and markers, segmental allopolyploids, and the degree of prediction accuracy in relation to pedigree.

Linkage Analysis and Haplotype Phasing in Experimental High Autopolyploid Populations with Applications in Sweetpotato

This presentation details the genetic mapping in complex polyploids work with hidden Markov models. It also discusses the linkage analysis in autopolyploids, as well as the MDS algorithm and HMM framework.

Linkage and QTL Mapping in Complex Polyploids

This presentation talks about the sweetpotato, its population numbers, the quantitative genotyping, and the genetic mapping. It then discusses QTL mapping, characterization, and dissection of the mapping.
