This study was conducted in almond genetic resources selected from Eastern and Western Turkey. 71 (Prunus dulcis (Miller) D.A. Webb) genotypes were selected from Balıkesir (Western Turkey) and Tunceli (Eastern Turkey) districts in 2012. Alpha (α)-tocopherol, gamma (γ)-tocopherol, delta (δ)-tocopherol and alpha (α)-tocotrienols and total vitamin E content were investigated in the selected almond genotypes. 38 almond genotypes from Balıkesir province had alpha-tocopherol, gamma-tocopherol, gamma tocopherol, alpha-tocotrienols and total vitamin E content to be from non detectable to 1164.36 mg kg⁻¹ oil, non detectable to 130.03 mg kg⁻¹ oil, non detectable to 81.38 mg kg⁻¹ oil, non detectable to 1252.24 mg kg⁻¹ oil, respectively. 33 almond genotypes from Tunceli district showed alpha-tocopherol, gamma-tocopherol, alpha-tocotrienols and total vitamin E content to be between non-detectable and 1085.92 mg kg⁻¹ oil, non detectable and 21.12 mg kg⁻¹ oil, non detectable and 91.26 mg kg⁻¹ oil, 0.86 and 1191.81 mg kg⁻¹ oil, respectively. Delta tocopherol content was not detectable in almond genotypes selected from Balıkesir and Tunceli provinces. BKS-3, BKS-16 and TUN-15 genotypes showed higher tocopherol content in comparison to the other genotypes tested. We can say that these genotypes could be a useful source for the future breeding projects in developing almond cultivars with high tocopherol content.
