Some Chemotaxonomic Characteristics of Local Garlic Genotypes

This study was carried out to determine some chemotaxonomic characteristics such as volatile sulfur compounds, mineral content and % protein of 7 garlic genotypes grown in Hatay province. The results revealed that the garlic genotypes have a large variation in terms of sulfur compound, mineral and % protein content. A total of 10 volatile sulfur compounds were detected, mainly diallyl disulphide and its amount in the genotypes varied between 41.51% and 59.48%. The highest value (59.48%) was detected in genotype Altınözü 2. The mineral content of determined in garlic genotypes also differed among genotypes. Genotypes Samandağ 2, Samandağ 3 and Hatay 1 had higher value in terms of Cu, Samandağ 1, Hatay 1 and Hatay 2 had higher value in terms of Zn, Samandağ 2, Altınözü 2, and Hatay 1 had higher value in terms of Na, Samandağ 1, Hatay 1, and Samandağ 3 had higher value in terms of K, Samandağ 1 had higher value in Ca and Fe, Altınözü 2 had higher value in terms of Mn, and Samandağ 2, Hatay 1, and Hatay 2 had high value in terms of Mg. The % protein content of the garlic genotypes varied between 4.77% and 7.71%. It is thought that this study will form a basis for the evaluation of these genotypes in breeding programs.
