The means of the BLUP values and heritability estimates for the 15 traits listed in the left column are reported in Table 2 and the values and estimates for the remaining traits are listed in Table S5.

Individual carotenoid compound measured by HPLC.

Derivative carotenoid trait.

Provitamin A is calculated as the sum of β-carotene, 1/2 α-carotene, and 1/2 β-cryptoxanthin.
