Fennel (Foeniculum vulgare Mill.) belongs to the Apiaceae family, is native to Mediterranean regions, is a biennial or perennial herb, and has feathery leaves and golden yellow flowers. Fennel is used for various purposes in the food, cosmetic, and medical industries. In this study, morphological traits and yield of 3 synthetic cultivars and their 7 elite parents of Iranian fennel under drought stress and normal irrigation were evaluated. Experiments were arranged as randomized complete block design in three replications with irrigation treatments (Irrigation after 60 mm, and 120 mm after flowering stage). The results indicated that all of the traits were significantly affected by ecotype and drought stress. Drought stress resulted in decreasing plant height, umbels per plant, seeds per umbel, umbelets per umbel, number of leaves and yield. The synthetic cultivar showed better properties containing desirable traits like higher yield than their parents. Finally based on yield and other desirable agronomic traits, it was recognized that these synthetic cultivars are suitable to be commercial cultivars.
