R Documentation

Flowering time data taken from Atwell et al. (2010).

Description

Two data-frames containing individual plant data on flowering time under different conditions: LDV (Flowering time under long days and vernalization) and LD (Flowering time under long days, without vernalization).

Usage

data(LD); data(LDV)

Format

Data-frames with flowering time observations, genotype and design information:

genotype: a factor, the levels being the accession or ecotype identifiers
LD: Flowering time under long days, in number of days
LDV: Flowering time under long days and vernalization, in number of days
replicate: The replicate (or block) each plant is contained in (factor with levels 1 to 6)
rep1: numeric encoding of the factor replicate: equals 1 if the plant is in replicate 1 and 0 otherwise
rep2: numeric encoding of the factor replicate: equals 1 if the plant is in replicate 2 and 0 otherwise
rep3: numeric encoding of the factor replicate: equals 1 if the plant is in replicate 3 and 0 otherwise
rep4: numeric encoding of the factor replicate: equals 1 if the plant is in replicate 4 and 0 otherwise
rep5: numeric encoding of the factor replicate: equals 1 if the plant is in replicate 5 and 0 otherwise

Details

All plants that had not flowered by the end of the experiment were given a phenotypic value of 200. Only accessions for which SNP-data are available are included here: 167 accessions in case of LD and 168 accessions in case of LDV.
