^aThe identified QTLs: the name contains trait initials, seedling growing stage, and the number of correspondent chromosome
^bThe percentages of phenotypic variation explained
^cThe QTL additive effect: positive values indicate that P014 provides increased alleles and negative ones indicate that E1312 alleles increased the trait
