  1. aBY: biomass yield, SPAD: leaf colour, ETR: electron transport rate at PSII, OA: osmolality, CSS: total content of soluble sugars
  2. bOne genomic region up to 2.6 cM (LD); the chromosomal position in cM was taken from the respective SNP with the highest R2
  3. cChromosome positions are based on Comadran et al. (2012)
