DHpop_geno


For this example, a doubled haploid population of 200 individuals was
developed by crossing a short line (parent A), with a tall line (parent B).
The 200 doubled haploid lines were evaluated in a field trial and the plant
height measured in cm (the data is in the file DHpop_pheno.txt).
The population was also genotyped by SNPs, and the data is presented in the
file DHpop_geno.txt.
The map location of each of the markers is in the file DHpop_map.txt.


datasets

Performs QTL mapping analysis for balanced and for
multi-environment and multi-trait analysis using mixed models.
Balanced population, single trait, single environment QTL mapping is
performed through marker-regression (Haley and Knott (1992) <DOI:10.1038/hdy.1992.131>,
Martinez and Curnow (1992) <DOI:10.1007/BF00222330>,
while multi-environment and multi-trait QTL
mapping is performed through linear mixed models.
These functions could use any of the following populations: double haploid,
F2, recombinant inbred lines, back-cross, and 4-way crosses.
Performs a Single Marker Analysis, a Single Interval Mapping,
or a Composite Interval Mapping analysis, and then constructs a final model
with all of the relevant QTL.
