Evaluation of Yield and Phytochemical Content of Different Iranian Garlic (Allium sativum L.) Ecotypes

Due to the development of garlic cultivation, quantitative and qualitative evaluations of garlic ecotypes in different regions are important for breeding purposes. In this study, some vegetative and phytochemical traits of eight Iranian garlic ecotypes were assayed in a RCBD with three replications at Darab Agricultural Research Station, Iran during ۲۰۱۷-۲۰۱۸ growing season. The results showed that there is a significant difference among garlic ecotypes in terms of studied traits (P <۰.۰۱). In general, Tarom and Tafresh ecotypes showed the highest plant height, number of leaves, length of garlic leaves, leaf width, fresh weight, dry weight and the highest bulb diameter. Highest dry weight of garlic bulb (g) per plant was obtained in Darab (۷۹.۰ g), Tarom (۷۵.۵ g), and Talesh (۷۵.۰ g) ecotypes, with no significant difference among them (P ≥ ۰.۰۱). Hamedan and Kerman ecotypes contained higher allicin content, alliin content, TPC, TFC, and TAC than the other ecotypes. Cluster analysis divided ecotypes into three distinct groups. Talesh and Hamedan ecotypes had the lowest similarity (۰.۳۴) and Darab and Tafresh ecotypes had the highest similarity (۰.۹۷). It can be concluded that Tarom, Tafresh, Hamedan, and Kerman can be recommended for cultivation depending on the quantitative (Tarom and Tafresh) and qualitative (Hamedan and Kerman) goals of cultivation
