In three years trials (1990-1993) the effect of diameter of bulbilson growth and yield of local garlic ecotype R was studied. Nine size classes of bulbils were investigated. Significant effect of diameter of bulbils on biometric properties and yield of local garlic was found out. The plants grown from big bulbils gave higher and better quality yield then those grown from smaller bulbils. There was no difference in yield of plants grown from big and medium bulbils.
