Estimated narrow (h2) and broad sense (H2) heritabilities of root length mean and variance in a population of 93 natural A. thaliana accessions.

1Estimated using ANOVA on accession,2Estimated using the R/hglm package (hglm) by fitting a linear mixed model including both additive and epistatic kinship matrices as random effects,3p-values from Wald tests for the heritability being larger than zero, and s.e. are the standard errors estimated via jackknife resampling.The broad-sense heritability estimates obtained using the phenotypic variances within and between accessions (H2 = VG/VP; ANOVA) and the genomic relationships of the accessions (H2 = (VA + VAA)/VP; hglm) were similar and intermediate. The narrow-sense heritability (h2 = VA/VP), estimated based on the genomic relationships between the accessions, was negligible.
