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+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.
