  1. Results of stepwise regressions for leaf length (Llength), leaf elongation rate (LERmax) and leaf elongation duration (LED) in spring and autumn on 'Herbie'. Are indicated: significant SNPs (P-value 0.15), the part of the phenotypic variation explained by each SNP (partial R2), the part of the phenotypic variation explained by all SNPs (global R2), the average value of each trait and the genotype effect compared to the average
  2. * 1/1 and 2/2 indicate the two homozygous classes and 1/2 indicates the heterozygous class
  3. a Pr > F is the is the probability of having a tabulated F value at least as extreme as the calculated one
