Table 4.
Genotype-phenotype association analysis results including markers that showed significant associations with berry fresh weight (BFW) (A), berry length (BL) (B) and berry width (BWi) (C) determined in a set of 41 grape varieties including table grape varieties (21) as well as core collection varieties (20), harboring a large proportion of the genetic diversity for Prole ‘Orientalis’ of Vitis vinifera. P-values of associations and variance explained by each SNP/InDel marker (R2) are indicated for the GLM models obtained for seasons 2016, 2017 and 2018. Statistically significant associations are in bold and highlighted with an asterisk (p < 0.05)
