^aPhysical position and number of positional candidates were derived by anchoring of the genetic map to grape genome assembly 12X.v2
^bBoth number of original QTLs for the meta-QTL calculation as well as the number of independent populations from which the overlapping QTLs were found are given.
^cThe kind of overlapping phenology related QTLs used for the analysis is indicated. Veraison QTLs overlapping with other phenology QTLs are highlighted in bold. QTL short name abbreviations are as following: ssc solubile solids concentration, Fw Flowering, Ma Malic acid, Tar/Ma Ratio of tartaric acid to malic acid, BB Bud break, FT Flowering time, RT Ripening time, VT veraison time, F-V Flowering-veraison interval, B-F Budbreak–flowering/Flo, FBL Time of full bloom, FS Start of flowering, VB veraison beginning, RDA Ripening date, Bpc Brix per cluster. Further details about phenotypes scoring can be found in the Additional file 2, Additional file 19 or in the indicated original publications.
^dReference of the study in which the QTLs included in the meta-QTL analysis were found
