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

1

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.
