Table 3 List of marker effects of significant marker–trait pairs

From: Single-nucleotide polymorphisms(SNPs) in a sucrose synthase gene are associated with wood properties in Catalpa fargesii bur

  1. aCalculated as the difference between the phenotypic means observed within each homozygous class (2a = |GBB − Gbb|, where Gij is the trait mean in the ijth genotypic class)
  2. bCalculated as the difference between the phenotypic mean observed within the heterozygous class and the average phenotypic mean across both homozygous classes [d = GBb − 0.5(GBB + Gbb), where Gij is the trait mean in the ijth genotypic class]
  3. Sp: Standard deviation of the phenotypic trait under consideration
  4. cThe additive effect was calculated as a = pB (GBB) + pb (GBb) − G, where G is the overall trait mean, Gij is the trait mean in the ijth genotypic class, and pi is the frequency of the ith marker allele
