means_floweringTime: Flowering time from Atwell _et al._ (2010): accession means.

Description Usage Format Details References See Also Examples


Accession means for the flowering time data contained in LD and LDV.




Data-frames with flowering time means:


a factor, the levels being the accession or ecotype identifiers


Flowering time under long days, in number of days


Flowering time under long days and vernalization, in number of days


Following Kruijer et al. (appendix A) these means were defined as the least-squares estimate for the factor accession, in a linear model containing both accession and replicate effects. Consequently there are differences compared to Atwell et al. (2010), where just the arithmetic averages are considered.

Together with the covariance matrices contained in R_matrix_LD and R_matrix_LDV, the means contained in means_LD and means_LDV can be used to estimate heritability, using the function marker_h2_means. For the corresponding genetic relatedness matrix, see K_atwell. For the individual plant data, see floweringTime.
