This study was conducted to determine volatile sulfur compounds and mineral content of mutant garlic genotypes. The volatile sulfur compounds analysis was performed with a gas chromatography-mass spectrometer. The mineral content of mutant garlic genotypes was determined with an atomic absorption spectrometer and flame photometer. The results indicated that mutant garlic genotypes showed large variation in terms of their content of volatile sulfur compounds and minerals. A total of 16 volatile sulfur compounds were detected, which were mainly diallyl disulfide (68.09%), disulfide methyl propyl (52.34%), disulfide methyl 2-propenyl (29.81%), sulfide allyl methyl (25.72%), diallyl sulfide (22.38%) and disulfide dimethyl (9.88%). The macro- and micro-elements detected in mutant garlic genotypes were K (232.45-513.25 mg L-1), Ca (2.19-7.35 mg L-1), Mg (7.38-21.64 mg L-1), Na (4.52-13.18 mg L-1), Cu (0.01-0.15 mg L-1), Fe (0.13-1.25 mg L-1), Mn (0.10-0.27 mg L-1), and Zn (0.12-0.69 mg L-1). As a result, it was determined that the content of both volatile sulfur compounds and minerals in mutant garlic genotypes was higher than in the control (cv. ‘Taşköprü 56’). The genotypes which had a higher content of both volatile sulfur compounds and minerals were GM1, GM8, GM18, GM20, GM21, GM22, GM33, GM35, GM36, GM37, GM39, GM40, GM46, and GM51. The research findings are extremely valuable in revealing the originality of mutant garlic genotypes obtained by mutation breeding, and establishing the foundation for an assessment of mutant garlic genotypes to be used in breeding programs.
