Seven QTLs for 3010 and eleven QTLs for CW 1010 were mapped on respective genetic linkage maps for phenotypic datasets of more than one environment and/or year.
The symbol with bracket in the column “year/location” indicates the source dataset from which the other parameters in the same row were pulled.
JPC environment dormancy data for the period: π1 = 2015, fall; π2 = 2016, fall; π3 = 2016, winter; π4 = 2017, winter.
BVL environment dormancy data for the period: β1 = 2015, fall; β2 = 2016, fall; β3 = 2016, winter; β4 = 2017, winter.
Across environment dormancy for the period: $1 = 2015, fall; $2 = 2016, fall; $3 = 2016, winter; $4 = 2017, winter.
