Tocochromanol means of Falcon and Azhul parents and two barley checks grown over four location years.

Means and heritability estimates were calculated for Falcon x Azhul (FA) RILs using combined years at each location.
aConcentrations given in µg/g. Values followed by the same letter or number of asterisks are not significantly different within a column (p<0.05). For means of genotypes within an form, a single asterisk is equivalent to A, two asterisks to B, and three asterisks to C.
+indicates an intermediate value.
bIrrigated field trial in Aberdeen.
cNon-irrigated field trial at Tetonia.
dBroad sense heritability calculated as genotype variance divided by cumulative variance including error.
