phenoSxT: Phenotypic Sunco x Tasman trial data frame

In wgaim: Whole Genome Average Interval Mapping for QTL Detection and Estimation using ASReml-R

Description

Phenotype data arising from a two-phase experiment involving a Doubled Haploid population from a crossing of the wheat varities Sunco and Tasman

Usage

data(phenoSxT)

Format

This data relates to a two-phase epxeriment involving a set of 175 Doubled Haploid lines. In the first phase DH lines were randomly allocated to plots using a complete block design with additional plots containing the parents (Sunco, Tasman) as well as commercial lines (Frame, Janz, Krichauff, Machete, RAC820, Trident). The trial was laid out in a rectangular array of 31 rows and 12 columns. In the second phase 23% of the field samples were replicated in the milling process producing a total of 456 milling samples. These partially replicated field samples were then randomly allocated to 38 mill days with 12 samples per mill day. The data frame consists of 456 rows with 11 columns. These columns are

Expt:

A one level of factor containing a unique identification for the experiment.

Type:

A factor of nine levels indexing the wheat variety (Doubled Haploid, Sunco, Tasman, (Frame, Janz, Krichauff, Machete, RAC820, Trident))

id:

A factor of 183 levels uniquely identifying the wheat varieties involved in the experiment.

Range:

A factor of 12 numeric levels indexing the field Range.

Row:

A factor of 31 numeric levels indexing the field Rows.

Rep:

A factor of 2 levels indexing the Block of the experiment

Millday:

A factor of 38 numeric levels indexing the milling day

Millord:

A factor of 12 levels indexing the milling order

myield:

A numeric vector of milling yield observations from the second phase of the experiment.

lord:

A centered numerical vector of milling orders, Millord

lrow:

A centered numerical vector of Rows
