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.
