The presented work is conducted at research farm for the vegetable plant, Department of Horticulture and Landscape Design, Agriculture and Forestry college, University. of Mosul, Throughout the autumn growing season 2018/2019, the major aim of this work is to determining the correlation as well as the path coefficient analysis in seven genotypes of garlic which were (Sinjari, Mankyshi, Iranian, Bakistani, lacal va., Kristal and Nader) collected from different origin and local market. The resulted indicated that the trait's mean squares have been highly considerable with regard to all traits indicating wide genetic variability between genotypes. The genotype local va. was best in leaf length, head diameter of height and head weight, also the number of leaves for each one of the plant while genotype Kristal gave a higher value in total yield ha-1 and biological yield. The result indicated significant and positive genotypic and phenotypic association between leaf length and the total yield, biological yield, T.S.S (Total soluble solid), weight, length and clove diameter showed negative correlation genotypic and phenotypic significantly with head length and number of cloves/head, while leaf's length through number of leaves plant-1, head diameter, clove's weight, and total yield showed maximum positive direct effects on total bulb yield. Clove diameter viz leaf length, biological yield, head weight, T.S.S, head diameter, number of cloves/head, clove weight, as well as clove length showed maximum indirect effect on the total yield per hectare.
